Intel Caught Commissioning Apparently Bias Benchmark Data for Core i9 9900K [Updated]

Category: CPU's
Posted: October 9, 2018 07:36AM
Author: Guest_Jim_*

Yesterday Intel officially announced many new CPUs, including the Core i9 9900K, an 8-core/16-thread CPU with a base clock of 3.6 GHz and a single-core boost of 5.0 GHz. The company calls it the world's best gaming processor, something that will likely be confirmed when the review embargo lifts on October 19. However, some early performance numbers are drawing more than just skepticism from some.

PCGamesN published performance data Intel had commissioned Principled Technologies (report PDF) to collect for it, comparing the 9900K against a number of CPUs, including the i7 8700K and Ryzen 7 2700X, across several games. According to this data, the 9900K possesses a significant lead in some games against the competing AMD CPU, in some cases reaching 30% to 50% better performance. The thing is, the numbers shared did not seem appropriate for some, including Steve Walton of TechSpot and Hardware Unboxed, who has previously and extensively benchmarked the already-released CPUs in at least some of these games, so he did some research. This research included not only looking through the report from Principled Technologies that is linked above from the PCGamesN article, but also trying to recreate the test systems.

Just going through the report, one issue identified was that the RAM was configured differently between the Intel and AMD systems. This is not in reference to the maximum supported speeds being used (2666 MHz for Intel and 2933 MHz for AMD) but to the Z390 system using an XMP profile with tightened timings, while the AMD system was left with the loose defaults, which will bias performance. Additionally, all of the DIMM slots were populated, which is apparently not optimal for Ryzen CPUs. Something else noted, though not by Steve, is that Game Mode was selected in the AMD Ryzen Master Utility, which on a Threadripper CPU, like the 2950X that was also part of the testing, will disable one of the two active dies, cutting the core count in half. Apparently this option is also present for the single-die 2700X, potentially cutting its core count in half as well, to just 4 cores.

After attempting to recreate the results shown between the 2700X and 8700K, the conclusion from Steve is "the Principled Technologies results are a load of rubbish." None of his tests showed the same gap indicated by the report, though the 8700K did consistently beat the 2700X. His testing included using identical memory configurations between the systems too, which improved performance for both Intel and AMD, but still not to what the report claims. As a result of this, PCGamesN has edited its original article, noting Steve's findings and has requested comment from Intel.

 

 

Update:

Steve has done some more testing and shared the results on the Hardware Unboxed Patreon page and while these results do actually come within margin of error of the Principled Technologies results, they do not ease the situation. These new results are from tests when Ryzen Master's Game Mode is enabled on the Ryzen 7 2700X, which Steve originally thought was only being used for the Threadripper 2950X. It turns out Game Mode is an option for the 2700X and does disable one of two CCX modules in on the die, making it a 4-core/8-thread CPU. Doing this with the loose timings gave him performance results in line with the Principled Technologies report, but it also means the report is pitting the 8-core/16-thread i9 9900K against the AMD CPU configured for 4-core/8-thread.

Intel Announces Many New CPUs for Desktop Gaming and Content Creation

Category: CPU's
Posted: October 8, 2018 11:46AM
Author: Guest_Jim_*


At long last, Intel has announced its newest generation of processors, stretching from the mainstream Core CPUs, through the X-series, and up to Xeon. For the Core series, we have the i5 9600K, i7-9700K, and i9-9900K processors. The 9600K has a base clock of 3.7 GHz and a single-core boost of 4.6 GHz for its 6 cores and 6 threads and will cost around $262. The 9700K is an 8-core/8-thread CPU, which means it does not sport Hyperthreading, but it does have a base clock of 3.6 GHz and can boost up to 4.9 GHz on a single core. The 9700K will cost around $374 while the 9900K at the top of the series will be approximately $488. The 9900K does feature Hyperthreading, making it an 8-core/16-thread CPU with a base clock of 3.6 GHz and a single-core boost of 5.0 GHz. All three are unlocked for overclocking. Also announced was the Z390 chipset that will pair these CPUs with integrated USB 3.1 Gen 2 and Intel Wireless AC. Pre-orders for these processors and Z390-based motherboards should be up today from various vendors and retailers.

Acer also announced refreshes of the Predator Orion 5000 and 9000 gaming desktops to incorporate the new 9th Gen Intel Core CPUs. Both will offer up to the i9 9900K though the Orion 5000 can come with up to a Nvidia GeForce RTX 2080 while the Orion 9000 can have up to an RTX 2080 Ti.

If you need more power than the Core i5, i7, or i9 above offer, Intel also announced seven new Core X-Series processors that go as high as 18 cores with the i9 9980XE. This high end CPU has a base clock of 3.0 GHz and can boost to 4.5 GHz using Turbo Boost 3.0 and will cost around $1979. At $1684 is the 9960X with 16-cores/32-threads and a base of 3.1 GHz but the same boost as its bigger brother. The 9940X will be $1387 for 14-cores/28-threads with a base of 3.3 GHz. Both the 9920X and 9900X have a base clock of 3.5 GHz and boost of 4.5 GHz, though the 9920 has 12-cores/24-threads for $1189 while the 9900X offers 10-cores/20-threads for $989. The 9820X also offers 10-cores/20-threads but has lower base and boost clocks at 3.3 GHz and 4.2 GHz. It also has less Intel Smart Cache available with only 16.5 MB compared to the 9900X having 19.25. The 9820X will cost around $898. At the bottom of the new X-Series stack is the i7-9800X with 8-cores/16-threads, a base clock of 3.8 GHz, a boost of 4.5 GHz, and a price of around $589. These processors will be available in November

If even the Core X-Series is not enough for you, Intel announced the Xeon W-3175X processor. This Xeon CPU has 28-cores/56-threads and a single-core boost of up to 4.3 GHz, but the part is also unlocked if you want to push it farther (and have the cooling to do so). The Xeon W-3175X will be shipping in December.

Threadripper 2970WX and 2920X CPUs from AMD Shipping October 29

Category: CPU's
Posted: October 5, 2018 01:35PM
Author: Guest_Jim_*

It was in August when AMD launched its second generation Threadripper processors, starting with the 2990WX with 32-cores/64-threads and followed by the 2950X with 16-cores/32-threads. Now the other two entries in the Threadripper 2000 series have been given shipping dates of October 29. These two processors are the 2970WX with 24-cores/48-threads and the 2920X with 12-cores/24-threads. The 2970WX has a base clock of 3.0 GHz and a boost of 4.2 GHz, matching the 2990WX but at a price of only $1299, compared to $1799 of its big brother. The 2920X has a base clock of 3.5 GHz and a boost of 4.3 GHz, so slightly less than the 2950X, but will only be $649. All Threadripper CPUs, first and second generation, sport 64 PCIe lanes and can work in all X399 motherboard, though a BIOS update may be needed for the second generation processors.

Also announced today is Dynamic Local Mode, a piece of software that should prove useful for those with a 2990WX or will be getting the 2970WX. Both of these CPUs use four active Zeppelin dies, but only two of them are connected to the system memory. This means the other two, which have up to eight active cores on each, need to reach across to another die to get at the DRAM, and not all applications tolerate the associated latency penalty. To address this, Dynamic Local Mode will run in the background on Windows 10 and gives priorities to application threads, based on how demanding they are. The more demanding threads are placed on cores with direct memory access, while the lowest threads are put onto other cores. The result can be a significant improvement to performance for various applications, including games.

Dynamic Local Mode will be available starting October 29 as part of AMD Ryzen Master. It is only for the Threadripper 2990WX and 2970WX, due to their memory access design. It will run as a Windows service, and can be switched on and off as one too, not needing a restart to take effect.

AMD Submits Linux Patches for 'Next Generation of Processors'

Category: CPU's
Posted: September 24, 2018 05:12PM
Author: Guest_Jim_*

They are still some months away, but it AMD's next series of CPUs are already appearing in patches for Linux. Today support for architectural extensions for Platform Quality of Service was added by a series of patches, with the next generation of processors specifically mentioned. The purpose of these extensions is for monitoring the usage of system resources, by one or more processors, and the allocation and enforcement of limits on these system resources, by one or more processors. The QoS sub-features these new processors will support are L3 Cache allocation enforcement, L3 Cache occupancy monitoring, L3 Code-Data Prioritization support, and Memory Bandwidth Enforcement (Allocation), according to the kernel mailing list.

As Phoronix notes, these features are likely only going to be enabled for the next series of EPYC processors, and not seen on the desktop Ryzen CPUs. Phoronix also notes these features seem similar to Intel Resource Directory Technology. We may see more information on the next series of AMD processors in the foreseeable future as at least the EPYC 2 CPUs they are expected in the first half of 2019 and will need Linux support when they launch.

AMD Announces Four Ryzen CPUs Spanning 4-Thread to 16-Thread

Category: CPU's
Posted: September 10, 2018 12:55PM
Author: Guest_Jim_*

It appears last week's announcement of new Athlon and Ryzen Pro CPUs from AMD was not enough as today AMD has announced four new Ryzen CPUs, from the Ryzen 3 2300X to the Ryzen 7 2700E. Starting with the lowest product number, the 2300X is a 4-core/4-thread chip, so we do not have SMT here, but we do have a base clock of 3.5 GHz and a boost of 4.0 GHz. Interestingly, according to Anandtech it and the Ryzen 5 2500X, a 4-core/8-thread chip, both use a single CCX, instead of two with half the cores disabled. The Zeppelin die used in the Ryzen CPUs all feature a pair of CCX's, which each hold four cores, and while previously we have seen AMD disabling cores symmetrically between the CCX pairs (2+2, 3+3, and 4+4), this is no longer the case. While both the 2300X and 2500X have the same 4.0 GHz boost, the 2500X has the higher base clock at 3.6 GHz. They also both have the same 65 W TDP. By using only one CCX, this means the L3 cache will be only 8 MB instead of 16 MB, but AMD is still claiming speed gains over the previous generation, perhaps thanks to the improvements offered by Zen+ and the removal of inter-CCX latency. Both chips support DDR4 2933 and neither will come with a cooler.

Moving up to the Ryzen 5 2600E, we have what looks to be a processor meant for greater energy efficiency. It is still a 6-core/12-thread chip, like the other Ryzen 5 2600 CPUs, but has a TDP of just 45 W. Its base clock is 3.1 GHz and its boost is 4.0 GHz. At the top of these new processors is the Ryzen 7 2700E, which has 8-cores/16-threads but with a base clock of 2.8 GHz and a boost of 4.0 GHz. The TDP for the 2700E is 45 W TDP, like the 2600E. Neither of these E parts will support Precision Boost Overdrive, which allows the power limits for the chips to be increased for greater performance, while there is still thermal headroom.

AMD Announces Athlon 200GE APU for $55 and More Pro Processors

Category: CPU's
Posted: September 6, 2018 07:57AM
Author: Guest_Jim_*

Today AMD announced a slew of new processors, with most being Pro versions of its 2nd generation Ryzen CPUs, but also the new budget Athlon 200GE was revealed, along with a Pro variant. This processor is targeting low cost computers as it is a 2 core/4 thread part clocked at 3.2 GHz, but it also packs in three Vega compute units so this one chip can get you up and playing some esports titles on its own. Of course the already available Ryzen 3 2200G would be more powerful, with hits more GPU cores and higher clock speed, but the Athlon 200GE has a TDP of just 35 W and a price of $55. It is an AM4 processor too, so you can drop it into any of the motherboards for that platform, either for a low cost, low power build or as a place holder until you can upgrade. It is a locked part though, so you will not be able to overclock it. Also, while details have not be disclosed yet, AMD also revealed Athlon 220GE and Athlon 240GE processors will be coming in Q4 2018. The Athlon 200GE will be available starting September 18.

AMD also announced the Pro versions of some 2nd generation Ryzen CPUs, which OEMs like Dell, HP, and Lenovo will integrate into their systems according to their launch schedules. The Athlon Pro 200 GE, Ryzen 5 Pro 2600, Ryzen 7 Pro 2700, and Ryzen 7 Pro 2700X exist to offer businesses the power of the Zen architecture while also having the reliability and security they need.

More Speculative Execution Vulnerabilities Discovered

Category: CPU's
Posted: August 15, 2018 08:44AM
Author: Guest_Jim_*

Though the public revelation of the Spectre and Meltdown vulnerabilities was many months ago, the impact is still being felt as more attack vectors on speculative execution are discovered. The latest discoveries go after the L1 cache in CPUs, and can even break into Intel's Software Guard Extensions (SGX). These L1 Terminal Fault (L1TF) vulnerabilities do not appear to affect AMD CPUs, Intel Xeon Phi processors, and older Intel chips. Also, two of the variants of L1TF vulnerabilities can also be mitigated via patches and updates released earlier this year, but the third is still an issue.

What these vulnerabilities involve is how CPUs handle virtual memory combined with speculative execution. Normally there is a page table that keeps track of the location of all items in memory, but as a lot of work is done and some pieces of data are not so needed, they will be taken out of physical memory and dumped onto a disc as virtual memory. When this happens the page table has that entry set as Not Present, and if the information is then requested, it has to be read into physical memory from the virtual memory location. With speculative execution though, this reading of the information into memory can occur earlier than the request, pulling it into memory. The vulnerability comes from an instruction trying to access an entry in the page table that has an invalid Present bit set, which then causes the information to be loaded by speculative execution, if it is in the L1 cache.

While the first two versions of the vulnerability can reportedly be mitigated by already existing patches, the third needs extra work, and current approaches can impact performance. This third involves virtualization and Intel Hyper-Threading, so it can be an issue for cloud platforms. Luckily there are no known examples of these vulnerabilities being used maliciously. Still, the security of speculative execution is continuing to be challenged. Intel has stated its next generation of Intel Xeon Scalable processors (Cascade Lake) will have the hardware-level changes necessary to address these and other issues.

The video below covers the vulnerabilities and is from Red Hat.

2nd Generation Threadripper Officially Announced by AMD

Category: CPU's
Posted: August 6, 2018 08:27AM
Author: Guest_Jim_*

The wait is over as AMD has officially announced its 2nd Gen Ryzen Threadripper HEDT CPUs, with the first pair releasing in one week, though pre-orders start today. At the top of the stack is the 2990WX, and just as the leak last week suggested, its 32-cores/64-threads have a base clock of 3.0 GHz and a boost of 4.2 GHz. The TDP for this processor is 250 W and it is launching on August 13 at the price of $1799. Also launching this month, but at the end (August 31), is the 2950X, which is the 16-core/32-thread part and it has 3.5 GHz base and 4.4 GHz boost clocks. The TDP of this part is 180 W and its launch price is $899, which is pretty nice since the 1950X it replaces launched at $999 last year.

Also announced, though not launching until October, were the 2970WX and 2920X, which are the 24 core and 12 core processors in the new lineup. The 2970WX shares the same clocks and TDP of the 2990WX, but will only cost you $1299. The 2920X will have a base clock of 3.5 GHz, a boost of 4.3 GHz, and a 180 W TDP when it launches at $649. Based on the stated L3 cache size, it is clear the two WX parts are using all four dies the chips hold, while the X parts are only using two active dies, as the WX CPUs have 64 MB and the X CPUs have 32 MB.

All of these new CPUs will work in existing X399 motherboards, though if you plan on dropping them into a current board, you may want to be careful about trying to overclock them, or at least the WX parts with their higher RDPs. To help keep things cool, CoolerMaster created the Wraith Ripper air cooler, which was shown off at Computex. The AMD press release says it is currently available, but at the time I am writing this, I did not see it on CoolerMaster's website.

Also revealed today is that last month at a special event, overclockers pushed a 2990WX to over 5.1 GHz on LN2, which allowed it to reach a record breaking score of 7618 in Cinebench R15. The previous single-socket record was held by Intel's i9-7980XE at 5828.

AMD Threadripper Specs and Prices Potentially Leaked

Category: CPU's
Posted: August 4, 2018 09:55AM
Author: Guest_Jim_*

This information might be among the more anticipated for CPUs this year, especially if it is accurate. VideoCardz has revealed leaked specifications and prices for the upcoming 2nd generation AMD Ryzen Threadripper processors, including the new 24-core/48-thread and 32-core/64-thread parts and the 12-core/24-thread and 16-core/32-thread upgrades to the already available CPUs. If this information is accurate, the current top-of-the-line Threadripper 1950X (which I am a proud owner of) that launched at $999 will be replaced in core count by the 2950X at $899 while the 2990WX, the massive 32 core part will take the top spot at a price of $1799. The 2970WX and 2920X, which are the 24 core and 12 core parts respectively, will cost $1249 and $649, respectively. A closer look at those prices though and you will notice doubling the cores here is doubling the price as well. It may also be worth noting that a replacement for the 1900X, an 8-core/16-thread 'entry-level' Threadripper is not mentioned. However, its launch price of $549 is not far from that of the 2920X ($649) so the intent might be for the 2920X to serve as the 'entry level' part, for those wanting the 64 PCIe 3.0 lanes all Threadripper processors offer.

Besides prices, the leak also gives base and boost clocks, and TDP. Both the 2970WX and 2990WX have the same clocks and TDP with a 3.0 GHz base, 4.2 GHz boost, and 250 W TDP. The 2920X and 2950X share the same 3.5 GHz base clock and 180 W (the same as the 1950X) but while the 2920X has a boost clock of 4.3 GHz, the 2950X will boost a bit faster to 4.4 GHz.

Until we know how well these parts may overclock, especially in existing motherboards, these CPUs at these specifications and prices could represent a healthy upgrade for some users. It has been stated that current X399 motherboards should support the new Threadripper CPUs following a BIOS update at stock settings. Increasing the power draw with overclocking might push some boards past their limits. Personally, I am still happy with my 1950X, but that $899 MSRP for the direct upgrade is definitely interesting.

2nd Generation Threadripper SKUs Apparently Discovered on AMD's Website

Category: CPU's
Posted: July 30, 2018 05:52PM
Author: Guest_Jim_*

It looks like the relevant pages have since been taken down, but Reddit user excalibur_zd had spotted on the AMD website support pages for what appear to be the second generation Ryzen Threadripper SKUs. While a completely fake SKU returns a 'Page no found' webpage, when the pages were discovered the results were blank, implying they are placeholders for when these processors are ultimately launched.

In total four different SKUs were found this way, with two making perfect sense; the 2920X and 2950X. The current 1920X and 1950X are the 12-core/24-thread and 16-core/32-thread parts that launched last year. The other two SKUs identified were the 2970WX and 2990WX, which are presumably the 24-core/48-thread and 32-core/64-thread processors shown off at Computex at the beginning of June. The 'W' in the SKU is rather curious though, leading to some speculation about what it could mean. Personally, I favor the idea that the W identifies these processors as using four active dies, as compared to the two active dies in current Threadripper parts. It is by using four active dies that AMD can reach 32 core physical cores, but two of these dies (16 physical cores) will lack direct memory access. Some applications may be sensitive to this while others will not be. The non-W versions, according to this theory, would then still use just two dies that have direct memory access.

Other theories are that the W versions will require water cooling, as the more active dies and active cores will produce so much more heat that air coolers will not be enough. Considering AMD actually showed off the CPUs at Computex running on an air cooler, and then showed off the air cooler, I find this doubtful. I believe the expectation is for these processors to be announced in August, so we will find out soon enough, along with other details, like price.

Due to issues with yields, Intel has delayed mass production of their 10nm CPUs until 2019. They just announced that they will be available for purchase during the 2nd half of next year, in time for the holidays. Because the 10nm probably won’t launch until Q4, the 14nm CPUs will still be the primary one used for most of the year. 

Intel’s CEO promised that 10nm datacenter products will be available soon after the 10nm-compatable client systems become available in late 2019. Intel confirmed that the codenamed Ice Lake-SP CPUs may hit the market in Q3 or Q4 of 2020. It might be worth waiting until October-ish to upgrade your CPU, if you can wait that long!

Author: Grilka8050


With Intel’s 9th Generation series launching soon, rumors are appearing all over the Internet. Coolaler, a reputable publisher of leaks in the past, has just released some rumored specs for the 9th Gen series. If these are legit, they could be really interesting! This leak includes specifications for the Intel Core i9-9900K, i7-9700K, and i5-9600K.

The first Core i9 processor is coming to the non-HEDT platform Z390. It has eight cores,16 threads, and is an unlocked SKU. Intel plans to offer 5 GHz in single and dual-core turbo modes. 

The i7-9700K has eight cores as well, but it does not include Hyper-Threading. The i5-9600K doesn’t have HT either and it is only a six-core processor. All three of these processors are 95W TDP, which is pretty impressive, especially for that i9. The base clock starts at 3.6 GHz and boosts up to 5 GHz. 

So what are your thoughts on these leaked specs? Are they exciting? Unbelievable? Underwhelming?

Specifications for 32 Core Gen 2 Threadripper CPU Possibly Leaked

Category: CPU's
Posted: June 19, 2018 01:47PM
Author: Guest_Jim_*

I still maintain that I am very happy with my AMD Ryzen Threadripper 1950X and do not need to upgrade, but if these rumored specifications are accurate, the temptation to start saving for an upgrade is growing. At Computex 2018, just two weeks ago, AMD showed off an upcoming 32-core/64-thread Threadripper CPU, and according to Anandtech the engineering sample demonstrated had a base frequency of 3.0 GHz and a Turbo of 3.4 GHz. Now, according to HKEPC, this part, which will supposedly be named the Threadripper 2990X, has a base clock of 3.4 GHz and a boost clock of 4.0 GHz across all cores, and 4.20 GHz for fewer cores. These numbers are based on a B2 stepping chip that HKEPC saw tested.

Under a Corsair H150i Pro AIO liquid cooler though, the chip supposedly reached 4.12 GHz across its cores with a voltage of 1.38 V, achieving a score of 6399 in Cinebench R15. That is pretty close to the 7334 score Intel achieved with its 28-core/56-thread CPU overclocked to 5 GHz at the conference. The Threadripper part, however, achieved its score without a one horsepower water chiller and while we do not know how much power it was pulling, I suspect it was less than the 1000 W the Intel processor was potentially drawing.

These numbers are definitely rumor currently, and could end up inaccurate, but it is still fun to imagine 64 threads going at 4 GHz, right? I wonder what a 2950X (what I presume would be the second generation 16-core/32-thread part) would be clocked at?

Binned and Delidded Intel Core i7-8086K Now Available at Silicon Lottery

Category: CPU's
Posted: June 18, 2018 11:08AM
Author: Guest_Jim_*

At Computex 2018, Intel revealed its limited edition Core i7-8086K CPUs, marking the 40th anniversary of the original 8086 processor. It appears the 8086K is already a specially binned version of the i7-8700K, as der8auer discovered at the conference, but this has not stopped Silicon Lottery from binning them again, based on their overclocking potential. Additionally, Silicon Lottery has delidded these CPUs, replacing the stock thermal paste under the IHS with Thermal Grizzly Conductonaut. The fact that Intel uses a thermal paste, or specifically the amount of paste used, has been something the company has come under fire for recently, especially compared to AMD's strategy of soldering most of its Ryzen CPUs. Replacing the stock thermal paste may result in better thermal performance.

The MSRP of the i7-8086K is $425 and it has a base clock of 4.0 GHz with a boost up to 5.0 GHz. The cheapest Silicon Lottery 8086K is $469.99 but has been successfully tested with a multiplier of 50, so overclocked to 5.0 GHz, at a Vcore of 1.400 V. This is the same multiplier/vcore pair as the 8700K offered by Silicon Lottery, though at the price of $429.99. All of the 8086Ks Silicon Lottery tested were able to reach 5 GHz or greater, while only 86% 8700Ks can do the same, and these are at the same settings, remember. Actually, I think comparing these test results might be interesting, so here is a table of them:

Multiplier Vcore (V) 8700K Percentage 8700K Price 8086K Percentage 8086K Price
50 1.400 86 $429.99 100 $469.99
51 1.410 50 $479.99 92 $499.99
52 1.425 17 $689.99 60 $589.99
53 1.435 N/A N/A 14 $859.99

Looking at these results, I wonder how much lower the Vcore could go for some of these 8086Ks.

By the way, it appears AMD is having a little fun with the one-day sweepstakes Intel held, where people could win a Core i7-8086K. Instead of keeping the limited edition CPU, you could instead send it to AMD, getting a Ryzen Threadripper 1950X CPU. Only the first 40 people from the United States to apply for the offer will be offered it.

Intel Announces Core i7 8086K CPU

Author: Guest_Jim_*


There were rumors about it back in April and new Intel has announced it will be releasing a limited edition Core i7-8086K CPU for the 40th anniversary of the original 8086 processor.

It is unquestionable the 8086 changed the world as it was the first 16-bit processor and brought about the x86 architecture that long dominated and still influences the computing world. In a way we still see it sued today, the x86 instruction set has changed greatly, with today's processors using x86_64, which AMD developed to bring about 64-bit computing while still supporting the older technology.

The Core i7-8086K will be Intel's first CPU to offer a single-core boost of 5 GHz, but being a K processor, it will be unlocked for overclocking. To get the CPU you can enter a sweepstakes starting 5 PM PDT on June 7. After the 24 hour entry period has closed, 8086 entrants will be randomly chosen to receive one. The second source link is to the sweepstakes webpage.

Possible Engineering Sample Zen+ AMD Threadripper Appears in SiSoftware Results

Category: CPU's

Author: Guest_Jim_*

If you have found the recently released AMD Ryzen 2000 series CPUs interesting but want more cores and threads to throw at your workloads, we may have just gotten a glimpse of the upcoming Threadripper refresh. Someone spotted over in the SiSoftware database what appear to be the results of an engineering sample for a new 16 core/32 thread part from AMD, which would be the replacement for the Threadripper 1950X. Of course this should be treated as a rumor, and even if it is accurate, engineering samples can differ from the final product, but it does show some interesting specs.

According to the data shown, this CPU had a base clock speed of 3.89 GHz and was using just 116.7 W of power for the multi-core efficiency benchmark. The 1950X has a base clock of 3.4 GHz and boosts to 3.7 GHz, though many users (including myself) have been able to successfully get it up to 4.0 GHz. Perhaps Zen+ will allow it to go even higher. For comparison, Intel's current i9-7960X, another 16 core/32 thread CPU has a base speed of 2.8 GHz but can boost to 4.40 GHz using Turbo Boost Max 3.0.

I have been thoroughly enjoying the power of my 1950X since I got it, and so I doubt I will feel the need to upgrade to this refresh, but I will admit I am very interested in what Precision Boost 2 will do with the 16 cores on two dies. Precision Boost 2 is the technology in the Ryzen 2000 CPUs some reviewers are touting as the reason you do not need to or want to manually overclock the processors. Manually overclocking all of the cores will leave some single-threaded performance untapped, according to their tests, and it will bring up the speed of all cores pretty well too. Applying this across two dies and 16 cores could make for an interesting beast of a processor. (I am still not considering upgrade, but I am now wondering what the price will be for a potential Threadripper 2950X, since the Ryzen 7 2700X was priced below the Ryzen 7 1700X at their respective launches. Of course the $1000 mark for the 1950X is still a great value, so the same price for better performance will be even better.)

AMD Might Still Launch a Ryzen 7 2800X

Author: Guest_Jim_*

Last week AMD launched its 2nd generation Ryzen CPUs, with the Ryzen 7 2700X at the top of the stack. If you remember the first generation products, you will remember the 1800X had been the top offering, with the 1700X below it. The lack of a 2800X led many to speculate for reasons why, but for AMD it is because the 2700X and Ryzen 7 2700 cover the performance and price points it was aiming for, with these new 8 core/16 thread parts. However, Jim Anderson, Senior Vice President at AMD apparently hinted a 2800X could appear on a later date, depending on Intel's response to the 2700X. Many of the reviews I have seen describe the 2700X as a worthy choice over Intel's Core i7 8700K, because while the 8700K can still offer greater gaming performance, the 2700X is not far behind, and with its addition two cores and four threads, it offers even better performance in multi-threaded workloads.

AMD 2nd Gen Ryzen CPUs Available Today

Author: Guest_Jim_*

The day has finally come and AMD's 2nd Generation Ryzen processors are available worldwide. The new CPUs are the Ryzen 7 2700X, Ryzen 7 2700, Ryzen 5 2600X, and Ryzen 5 2600, with the Ryzen 7 parts being 8 core/16 thread processors and the Ryzen 5 are 6 core/12 thread chips. The MSRPs span from $199 for the Ryzen 5 2600 to just $329 for the Ryzen 7 2700X.

The CPUs are being manufactured on a new 12 nm LP process that should allow for higher clock speeds than the first generation of Ryzen processors, but there are more improvements than this. The Zen+ architecture has increased IPC compared to Zen and has improved cache and memory latencies, Precision Boost 2, and XFR 2 to further improve performance. (Some features require the new X470 chipset, though the CPUs themselves will still work on X370, following a BIOS update.) The Ryzen Master Utility has also seen an update to unlock new overclocking capabilities.

Reviews and Overclocking Results Appearing for 2nd Generation Ryzen CPUs

Category: CPU's

Author: Guest_Jim_*

Despite the embargo on the 2nd Generation Ryzen CPUs ending on Thursday, there has been a lot of information coming out sooner. The outlet El Chapuzas Informatico has been putting up reviews in fact, which VideoCardz has nicely collected and shared as well, with the latest review being of the Ryzen 5 2600 on the X470 platform. This is somewhat interesting as the 2600 was not in the review kits AMD sent out, but instead it was the 2600X and 2700X reviewers were getting. In any case, according to this review, the 2600 was able to reach 4099 MHz on all of its cores using 1.45 V, on the MSI X470 Gaming Pro Carbon motherboard. The memory kits used when testing gaming performance are unfortunately inconsistent across the tests, but graphs show it directly competing with the Core i7 8700K in Doom, even though the Intel CPU had faster RAM (DDR4 3600 compared to DDR4 3200). In both Doom and Battlefield 1 only the i5 8600K with DDR4 3600 came ahead of it by a noticeable amount, which would be a very nice result for a $199 processor.

In a review of the Ryzen 7 2700X, again we see the i5 8600K with DDR4 3600 ahead of the AMD offering in Battlefield 1. In Doom the i7 7800X, i7 8700K, and i5 8600K are all ahead, with the 7800X only leading by 2 FPS. All of the Intel CPUs were using DDR4 3600 while the 2700X was using DDR4 3200. If these and the other results shared are accurate, the Ryzen 7 2700X, and it appears the Ryzen 5 2600, are able to directly challenge some of the best performing Intel CPUs.

Finally, and this does not come from El Chapuzas Informatico, the Ryzen 7 2700X has been overclocked to 5884 MHz, which would be a record for the Ryzen 7 series. A Ryzen 5 1600X has reached 5905 MHz, so that record would still stand, but 5884 MHz is hardly a poor showing.

Just a few days to go before the embargo lifts and more information hits the Internet.

Intel Might Be Making a Core i7 8086K for x86 Anniversary

Category: CPU's
Posted: April 16, 2018 12:02PM
Author: Guest_Jim_*

It was 40 years ago when Intel launched its 8086 CPU, a processor that left a deep impact on the whole of the computer industry. Its success led to the rise and dominance of the x86 instruction set that we still use today in the form of x86_64, for 64-bit processors. With this anniversary of its June 1978 release approaching, images have appeared of an Intel Core i7 8086K CPU, and the speculation is it might be a Coffee Lake chip specially binned for high performance.

With the convergence of the anniversary and Intel's current CPU series being the 8000 series making such a product a seemingly perfect fit, it is entirely possible this is a hoax. June is not too far off though, so if it is not a hoax, we may not have long to wait for official statements to that effect.

Author: Guest_Jim_*

Following the success of the first generation of Ryzen processors from AMD, many have been looking forward to the launch of their successors. Today pre-orders have gone live for the four 2nd generation Ryzen processors that will be available April 19. These CPUs are the 8 core/16 thread Ryzen 7 2700X and 2700, and the 6 core/12 thread Ryzen 5 2600X and 2600. All of the processors will come with an AMD Wraith cooler, though the specific model differs between them.

The 2700X has a base clock of 3.7 GHz and will boost to 4.3 GHz, has a TDP of 105 W and comes with the Wraith Prism cooler for $329. The 2700 cuts back on the clock speeds, to a 3.2 GHz base and 4.1 GHz boost, but its TDP is also at 65 W. The 2700 comes with the Wraith Spire and will cost $299.

The 2600X has a base clock of 3.6 GHz and boosts to 4.2 GHz with a TDP of 95 W. It also comes with a Wraith Spire cooler, but lacks the LEDs, and will only cost $229. At the bottom of the pack is the 2600 with a base clock of 3.4 GHz and boost of 3.9 GHz, a TDP of 65 W, and a Wraith Stealth Cooler. It will only cost you $199.

The AMD X470 chipset will also be launching on April 19 and will be able to utilize some of the new CPUs features the older, but still supported, X370 chipset does not enable. A free download of the AMD StoreMI software is included with the X470 chipset, allowing users to combine high speed and high capacity drives in an easy-to-manage way.

Ryzen 5 2600 Review Posted Before Launch

Author: Guest_Jim_*

With the great success of AMD's Ryzen 1000 processors, many have been looking forward to the launch of its successors, the Ryzen 2000 series of CPUs that are to launch sometime this month. Though we are not yet to the release date, some information is leaking out, including a review by El Chapuzas Informatico of the Ryzen 5 2600, which VideoCardz found and shared some of. While this second generation 6 core/12 thread part does show some nice if only moderate improvements from the Ryzen 5 1600, the tests have some issues with them. For one thing, they were done on an X370 motherboard so X470-exclusive performance-improving features are not present, and the platform was not completely stable for gaming tests. As the release date approaches we will hopefully see more reviews more representative of the consumer platform.

Also shared by VideoCardz is a video from AMD's YouTube channel looking back at the Ryzen processors, one year after release. Something mentioned in the video is that work has already begun on the Zen 5 CPU architecture, which will follow the Zen 3 design. Both Zen 2 and Zen 3 will be 7 nm designs and Zen 2 will be the company's first CPU with a fix for the Spectre vulnerabilities, but there are limited details beyond these. If you are wondering what happened to Zen 4, apparently four is often skipped due its unlucky meaning in Chinese culture. The earliest VideoCardz speculates we might see Zen 5 launch is 2021, since Zen 3 is supposed to release in 2020.

Intel Apparently Not Patching Some Old CPUs for Spectre V2 Protection

Category: CPU's
Posted: April 4, 2018 04:00PM
Author: Guest_Jim_*

After their public reveals in January, a number of companies, including Intel, have been working on mitigations and protections against the Meltdown and two Spectre vulnerabilities. All three attacks take advantage of how a performance improving feature built into CPUs work but there are software and firmware solutions to at least reduce the vulnerability to these attacks, if not completely stop such attacks. While Intel has already release microcode updates for a number of its processors, it looks like some of its older chips will not be seeing these updates. The good news is the newest of these processors went on sale in 2011, so it is only older systems that will not receive these updates.

It is only protection against the Spectre Variant 2 attack that has been stopped, and only for chips in the Bloomfield Xeon, Clarksfield, Gulftown, and Yorkfield families. The reasons giving for these stops include it being impractical to implement these changes due to micro-architectural characteristics, limited ecosystem support, and that many customers use these machines in a closed system, making it less likely for them to be exposed to a threat. However, there are microcode updates for Spectre v1 and Meltdown, and Meltdown was a very serious threat given the ease with which it could be exploited.

Information for Intel's 8th Gen Core CPUs using Coffeelake-S have been revealed now and VideoCardz has put together a nice chart for them and four chipsets. Starting from the top, the Core i7-8700T is a 35 W processor but will have 6 cores/12 threads running with a base clock of 2.4 GHz and a boost of 4.0 GHz, costing some $303. Stepping down to the Core i5 we still have six cores but only six threads and the i5-8600 leads this pack with a base clock of 3.1 GHz and a boost of 4.3 GHz at a 65 W TDP and $213 price. The i5-8600T has lower base and boost clocks, 2.3 GHz and 3.7 GHz, but a 35 W TDP, which is likely why it also has the same $213 price to it. The i5-8500 and 8500T are a pair that also share the same price, but the 8500 has a 65 W TDP for its 3.0 GHz/4.1 GHz base/boost clocks while the 35 W TDP of the 8500T has 2.1 GHz/3.5 GHz for its clocks. At the bottom of the i5 range is the i5-8400T with its 1.7 GHz base, 3.3 GHz boost, and 35 W TDP for a price of $182. Coffeelake-S is also in three i3 processors and all are 4 core/4 thread parts. The 8300 has a base clock of 3.7 GHz with a 62W TDP and $138 price, while the same-priced 8300T has a base clock of 3.2 GHz and a 35 W TDP. At the very bottom is the 8100T and its 3.1 GHz base clock, 35 W TDP, and $117 price.

For chipsets we have the H370, H310, and B360 targeting consumers and the Q370 targeting corporate users, though the H370 and B360 also aim at corporations. The H370 has 20 PCIe lanes, the B360 has 12, and the H310 has 6 while the Q370 offers up to 24. The H370 and Q370 chipsets both offer 30 high speed I/O lines and a total of 14 USB ports, though the Q370 can support 10 USB 3.1 ports while the H370 only offers up to 8. The B360 has 24 high speed lines and 12 total USB ports while the H310 comes in at 14 high speed lines and 10 USB ports.

It was back in January that the news of the Spectre and Meltdown CPU vulnerabilities were first reported and since then many companies have been working to protect against potential attacks. Most of these solutions have been in software, which can be enough and can be developed quickly, but since the original release, hardware-level fixes have been discussed for finally blocking potential attacks.

Intel, which was the only company with products susceptible to Meltdown and both variants of Spectre, recently stated it has released new microcode for all of its products from the past five years that were vulnerable to these side-channel attacks. Naturally this means you must install these updates to protect your system. To provide even more protection against the second variant of Spectre and against Meltdown, Intel has also developed hardware design changes and these will be present in its next generation Intel Xeon Scalable processors, which have the code name Cascade Lake, and in 8thsignificant performance penalties for some workloads.

Specs and Performance Data Found for Upcoming AMD Ryzen 2000 CPUs

Author: Guest_Jim_*

Last week slides claiming to contain specification and pricing information about AMD's upcoming Ryzen 2000 series processors appeared on the Internet, and now it appears some of this information is accurate as some of the CPUs are also appearing in benchmark databases. Over at Geekbench, the Ryzen 5 2600X and Ryzen 7 2700X have been spotted, showing 3.6 GHz and 3.7 GHz base clocks respectively. The single-core performance was 4781 and 4736 for the 2600X and 2700X respectively, while the multi-core score gives the 8 core/16 thread CPU a clear lead at 25,195 compared to the 22,235 score of the 6 core/12 thread processor. It might be worth noting different speed RAM was used between these tests, so they are not apples-to-apples, and both motherboards reported as using the X370 chipset, so the performance-improving features expected of the X470 chipset were not present.

Geekbench is hardly the only benchmark out there and people have found entries for the 2700X and 2700 (non-X) in the 3DMark database. The scores here are not necessarily as useful as you would hope due to the memory speed and configuration used, but the maximum turbo clock is shown as 4 GHz for the 2700 and 4.35 GHz for the 2700X, with the 2700 also having a base clock of 3.2 GHz. For the most part this all aligns with last week's leak.

Also found recently is the Ryzen 5 2600 in the SiSoft database, where it is identified as having a turbo clock of 3.9 GHz.

Several Security Flaws Reported in AMD Processors and Chipset

Earlier today a number of security vulnerabilities were revealed in various AMD CPUs and the Promontory chipset, though not technically disclosed, by CTS, a cyber-security company, at the AMDFlaws.com website. Some of these involve compromising the Secure Processor built into some processors, allowing malicious code to exist at a level invisible to the operating system. There are a total of 13 vulnerabilities, according to CTS, falling under four groups it has named Masterkey, Ryzenfall, Fallout, and Chimera. According to the whitepaper, there are no known mitigations for any of these attacks but, well, there are some questions about the validity of these vulnerabilities and how their disclosure today has been handled.

Typically when a security vulnerability is found, it is reported to the effected company 90 days before it is published, and sometimes this period is extended. AMD however was only notified of these claims yesterday, so AMD has had little time to investigate the issues or identify any mitigations. Also, while these issues may compromise the security of a Zen-based computer, to even attack the vulnerabilities is not going to be trivial. In the case of Masterkey, a specially crafted BIOS would need to be flashed to exploit a vulnerability in the Secure Processor and place malware code within the ARM Cortex A5 processor that is inside the Secure Processor. Ryzenfall, Fallout, and Chimera all require local-machine elevated administrator privileges to run a program and a digitally signed driver to access the Secure Processor. Chimera specifically goes after the Promontory chipset, which was created by ASMedia and not AMD directly, and CTS is pointing out security issues ASMedia has had as the basis for this vulnerability. The only footnote about these vulnerabilities is the FTC penalizing ASUSTek, of which ASMedia is a subsidiary, because of vulnerabilities in routers.

Only time will tell how serious any of these issues might be, especially as AMD begins its investigation into the vulnerabilities, along with other security researchers.

AMD CPU Desktop Platform Roadmap Apparently Leaked

Yesterday saw the leaking of potential pricing and specification information for the upcoming AMD Ryzen 2000-series of CPUs, but that was not the only AMD leak of the day. This one apparently came from a special event for retailers and distributors and shows the desktop CPU architecture roadmap to 2020, covering CPUs, APUs, and HEDT CPUs.

The start of the roadmap is 2017, so it shows us some information we are already familiar with, but some of the 2019 and 2020 names are new, as is the description of the release cycle. According to the roadmap, 2019 will see the release of Matisse, the Zen 2 AM4 CPU, Picasso, the AM4 APU, and Castle Peak for the HEDT CPU. In 2020 the AM4 CPU launched will be Vermeer and the AM4 APU will be Renoir. The HEDT CPU for 2020 does not have a codename here and is labeled as just NG HEDT. Beneath the road map the yearly releases are marked as being Inflection releases, meaning a new fabrication process and new CPU core, or Optimization coming from process maturity and efficiency enhancements. The Inflection releases follow what we already know, with 2017 and 2019 both labeled as such (the releases of the Zen and Zen 2 architectures), and the Optimization for this year agrees with the Zen+ release coming next month. The Optimization mark for 2020 makes sense too, just following a cycle of introducing new technology and then refining it before the next major introduction.

Another leaked slide shows the lineup for the upcoming Pinnacle Ridge SKUs, though at least one aspect of it is a little curious. According to this slide, there will not be a Ryzen 7 2800X CPU and the Ryzen 7 2700X will fill the slot for both the 1700X and 1800X. I have been seeing some comments that removing the x800X SKU makes sense as a means to reduce confusion between three top-of-the-line parts. What is a little odd though is the label above the 2000-series CPUs: 2H 2018. The current expectation or hope is these processors will be launching next month, which would be Q2 and still in the first half of the year. The slide does also say "Schedule subject to change" but we will have to wait and see what happens.

Ryzen 2000 Specs and Pricing Possibly Leaked

Next month is when the Zen+ based and 12 nm fabricated Ryzen 2000 series of CPUs from AMD are supposed to launch, but it appears a lot of information about them has leaked out. Like all leaks, these should be considered rumors and not completely trustworthy, but time will tell, and it might not even be long. The leak comes as slides from and in the lower left corner the NDA information is stated, including the embargo date of March 15, which means, if this is true, we might see it confirmed just next week.

On to the details which show four Ryzen 2000 CPUs launching: 2600; 2600X, 2700; and 2700X. Like the 1000 series, the 2600(X) CPUs are 6 core/12 thread parts while the 2700(X) are 8 core/16 thread parts but they all come with a cooler, something that was not the case for the X-series CPUs before. You might notice the lack of a Ryzen 7 2800X, replacing the top-binned 1800X, which is fueling some speculation about when it might appear and what its specifications will be. According to the slides, the 2700X will have a base clock of 3.7 GHz and a boost of 4.35 GHz with a TDP of 105 W. Its price will be $369 while the 2700 will cost $299, have a base clock of 3.2 GHz and a boost of 4.1 GHz in its 65 W TDP. Naturally the 2600 and 2600X come in cheaper at $199 and $249 respectively, along with base clocks of 3.4 GHz and 3.6 GHz with boosts of 3.9 GHz and 4.25 GHz respectively. The TDPs for these two chips are 65 W and 95 W, with the 2600X naturally being the higher power part.

The 2000 series offers more than just higher speeds but also other internal improvements, such as Precision Boost 2, which has been talked about before. Precision Boost is meant to increase the clock speed of a CPU's cores depending on the workload and situation with Precision Boost 2 being able to do so at a finer level, extracting more performance from the chip. Also XFR 2 will push the CPUs to higher speeds, based on the chip's temperature, but the X-series processors have more than these two technologies to improve performance. Precision Boost Overdrive and XFR 2 Enhanced will bring the speeds even higher for these CPUs, but only on the X470 and B450 chipsets. If you want these features, you will need one of the newer motherboards and not one of the current 300-series motherboards with a BIOS update.

Also among the slides are a couple comparing performance between the 2700X and either the 1800X or Intel Core i7-8700K. According to these slides, the 2700X is on average just 7.7% below the 8700K in performance, at 1080P ultra with a GTX 1080, and on average 5% faster than the 1800X.

Personally I am looking forward to March 15, to see if these slides come out officially and what other information might come with them.
