Author: scr4wl

Long-term Intel CPU Engineer Francois Piednoel has recently tweeted that he will be leaving the company. In the tweet, Piednoel said, "I am informed my management that I do not wish to continue my employment at Intel. New adventures coming, very exciting!" Piednoel, who has worked for Intel for the past twenty years as a senior architecture engineer, was involved in the development of some of Intel's biggest CPU architectures. The list of projects he worked on includes Katmai, Conroe, Penryn, and Nahalem. Further, he also had a hand in developing SoC's in Sandy Bridge, Ivy Bridge, Haswell, Broadwell, Skylake, and Kaby Lake. While nothing is known what Piednoel will do now that he has resigned, there is no talk of him moving to AMD. In fact, according to this source, Piednoel has rejected that assumption.

Author: scr4wl

It is reported that Intel will release new 6-core CPUs, based on the Coffee Lake architecture, in a few months. On the high end, the i7 8700K should come in clocked at around 3.7GHz and provide a total of twelve threads when Hyperthreading is enabled. At 95W, the i7 8700K will have a much lower TDP than the Core i9 7800X and its TDP of 140W. Intel will be releasing an i7 8700 non-K series, which will be clocked at around 3.2GHz. The rumor mill is also suggesting that we will see 6-core CPUs in the i5 series, although Hyperthreading will be disabled.

It is also said that for the first time ever, Intel will be introducing pure mobile 6-core CPUs. As you can imagine, Coffee Lake mobile will have much lower clock speeds at around 2GHz, and a much lower TDP at 45W. Finally, it is also reported that we will see a Coffee Lake quad-core CPU featuring a 28W TDP and targeted at low power notebooks.

Intel Calls AMD's Naples '4-Glued Together Desktop Dies'

Intel takes the offensive in its recent press workshop as it points out many of Naples, so called, shortcomings. Intel presented several slides explaining the downsides of AMD's recent offering, even going so far as to call it "4-Glued Together Desktop Dies." Intel further points out that Zen is AMD's first new architecture in six years and that AMD's new architecture will stick around for four. Intel was happy to compare its new Skylake-SP architecture to Naples, noting that Skylake-SP is 28 "true" cores. This seems to be somewhat reminiscent of the Core 2 Quad days, when Intel was combining dies to create multi-chip packages and AMD was producing a "true" quad-core chip.

As you would expect from slides coming from Intel, a lot of the information is pro-Intel and anti-AMD. That said, there is some good information about Intel's Skylake-SP architecture. The slides touch upon Skylake-SP's improved virtualization and VM performance, as well as it's improved SMT performance. As with the rest of the slides, Intel doesn't hesitate to point out that Skylake-SP has more than double the memory bandwidth, and close to double the PCIe bandwidth, of AMD's offering. Regardless of what Intel may say, I for one am glad to see AMD releasing some competition again.

AMD Reveals Some Threadripper and R3 Information

Category: CPU's
Posted: July 13, 2017 04:59PM
Author: Guest_Jim_*

At long last AMD has finally released some specs for the upcoming Ryzen Threadripper and Ryzen R3 CPUs, which complete the Ryzen lineup at the top and bottom, respectively. The two R3 processors are 4-core/4-thread CPUs with the R3 1200 sporting a base clock of 3.1 GHz and a boost of 3.4 GHz, while the R3 1300X will have a base of 3.5 GHz and a boost of 3.7 GHz. The R3 CPUs will also be launching later this month on July 27, and as they use the AM4 socket they can installed in the already available A320, B350, and X370 motherboards.

For those looking for high end desktop (HEDT) CPUs, we not only have some clock speed information on the Threadripper processors but even prices and a release window. Starting at the top, the Ryzen Threadripper 1950X, with its 16 cores and 32 threads, will have a base clock of 3.4 GHz and a boost of 4.0 GHz. Its suggested retail price is just $999, matching Intel's 10-core/20-thread i9-7900X CPU (3.3 GHz base with 4.3 GHz boost under Turbo Boost 2.0 or 4.5 GHz with Turbo Boost 3.0). The 12-core/24-thread Threadripper 1920X has a base clock of 3.5 GHz and a boost of 4.0 GHz and will be priced at $799. The video embedded below also shares some performance numbers for these CPUs from Cinebench R15.

These two Threadripper CPUs will be available early August, and we will also be getting more details on them following the R3 launch later this month. Do not forget that at SIGGRAPH, also the end of this month, more information on Vega GPUs will be released as well.

Author: Nick Harezga

Intel announced its next generation Core i9 CPUs late last month, but didn't set a release date for all of the announced models. The company has now remedied that with release dates for the Core i9-7980XE 18 core, i9-7960X 16 core, i9-7940X 14 core, and i9-7920X 12 core CPUs. The 12 core model will be available first in August, with the 14, 16, and 18 core models hitting the market in October. These models join the i9-7900X and lower models that will be available sometime this month. The prices will range between $1199 for the 7920X to $1999 for the 7980XE, which puts these CPUs out of reach for most consumers. It will be interesting to see how much more performance users are able to achieve for the premium price tag.

Intel Announces X-Series CPUs with Pricing Information

Category: CPU's
Posted: May 30, 2017 07:26AM
Author: Guest_Jim_*


Yesterday, we covered that Intel was planning to launch an 18 core/36 thread Core i9 CPU, and indeed the company has announced this behemoth, along with the rest of the X-series of CPUs. While we do not have launch dates for all of the processors yet, and many are just labeled as Q2 2017, we do have prices for the entire line. At the bottom of the pack, the four core/four thread Core i5-7640X will cost $242, while the four core/eight thread Core i7-7740X will be at $339. The six core/12 thread i7-7800X is not too much more expensive at $389, but then the eight core/16 thread i7-7820X jumps up to $599. This is more expensive than AMD's Ryzen 7 series that also features eight core/16 threads, but the i7-7820X has a base clock of 3.6 GHz, matching the Ryzen 7 1800X, and a boost clock of 4.3 GHz with Turbo Boost 2.0 or 4.5 GHz with Turbo Boost 3.0. The Ryzen 7 1800X only boosts to 4.0 GHz.

If you want more than eight cores/16 threads, there will be the i9-7900X that has a base clock of 3.3 GHz and boosts to 4.3 GHz under Turbo Boost 2.0 or 4.5 GHz under Turbo Boost 3.0. It will cost you $999, however. The i9-7900X is the last of the X-series we have much information on, with the higher-end parts only sharing core/thread counts and pricing. The Core i9-7980XE with its 18 cores and 36 threads is sitting at the top with a cost of $1999, while the 16 core/32 thread i9 7960X is at $1699. We do not yet know the pricing for AMD's 16 core/32 thread Ryzen Threadripper processors, but at least now we can see what it may most directly compete with. With 14 cores/28 threads, the i9-7940X will cost $1399 and the 12 core/24 thread i9-7920X will be just $1199.

As you can see, Intel has its X-series of processor set to stretch quite a range of markets, and each uses the same X299 chipset and LGA 2066 socket. You can check out the source links below for more information, especially the PDF with its charts.

Intel to Launch Core i9-7980XE CPU With 18 Cores

Category: CPU's
Posted: May 29, 2017 11:20AM
Author: Guest_Jim_*

It was not too long ago that AMD announced its upcoming Ryzen Threadripper HEDT CPUs with 16 cores/32 threads and now we are seeing reports that Intel is going to release an HEDT with 18 cores/36 threads named the Core i9-7980XE. This very high end part will be at the top of the new X-series processors that will apparently stretch from four cores to that huge 18 core offering, adding two cores with each step, according to Videocardz's sources.

All of these processors will use the X299 chipset and LGA 2066 socket, but they will not all have the same set of features. Only the 7820X and above will have Intel Turbo Boost Max Technology 3.0 and support up to four channel DDR4 2666 RAM. Naturally these CPUs will also have different TDPs, with some coming in at 165 W, others at 140 W, and the 7640X and 7740X (both quad-core parts) will be at 112 W.

The X-series is going to have new boxes as well, and according to a chart Videocardz put together, the 10 core/20 thread 7900X and lower CPUs will be launching in June, while the 12 core/24 thread 7920X will be launching in August. The higher end 7940X, 7960X, and 7980XE do not have a launch date specified yet. The chart also shows a range of base and turbo clock speeds, from 3.3 GHz/4.5GHz for the 7900X to 4.0 GHz/4.2 GHz for the 7640X. Check it out if you want to see where these CPUs will fall, but the top of the chart is lacking a lot of data currently.

AMD Engineering Samples with 16 Cores/32 Threads Possibly Found

Category: CPU's
Posted: May 11, 2017 10:51AM
Author: Guest_Jim_*

This is definitely in the 'rumor' column as someone appears to have found engineering samples of some as-yet unannounced AMD CPUs. Among them are two CPUs with 16 cores/32 threads with base clocks of 3.1 GHz and boost clocks of 3.6 GHz. These are labeled as the AMD Whitehaven platform and as they are first and second generation engineering samples, those clock speeds could increase by the time they release. There are a number of other CPUs mentioned, including some with just four cores and one with only two cores, but each supports SMT and therefore sports double the threads.

As the Videocardz source points out when it breaks down the numbering system for these CPUs, the two 16 core/32 thread chips are using a different socket than AM4 or SP3 (a server socket). There have been rumors previously that AMD is planning a separate X399 chipset targeting high end desktops (HEDT) that would also have a different socket. Allowing these rumors to have some truth to them, these may be CPU destined for that platform, and with a better-than 3 GHz clock speed, these could be some fairly powerful components. Only time will tell though.

Intel Fixes Remote Vulnerability That Goes Back to 2008

Category: CPU's

Author: Nick Harezga

Intel has fixed a vulnerability in the Active Management Technology (AMT), Standard Manageability (ISM), and Small Business Technology (SBT) firmware versions 6 to 11.6, impacting processors going back to the Nehalem based Core i7. This allows attackers "to gain control of the manageability features provided by these products," which "means it is possible for hackers to log into a vulnerable computer's hardware – right under the nose of the operating system – and silently tamper with the machine, install virtually undetectable malware, and so on." AMT has direct access to the networking features of your computer, allowing this to be exploited remotely. It is believed that business and server systems will feel the most pain from this as these systems commonly have the impacted features enabled. Intel has published instructions on how to determine if you system has the features enabled, and you should be sure to check your system.

Author: Nick Harezga

AMD is planning to release a BIOS update to fix an issue in the Fused Multiply-Add (FMA3) code that is causing systems with a Ryzen CPU to hang. The company didn't provide details on what the specific issue was but stated, "We are aware of select instances where FMA code can result in a system hang. We have identified the root cause." The problem was first noticed using the Flops v2 benchmark, but it was also noted that "simple apps with basic user privileges can crash a Ryzen-based machine."

Ryzen 5 CPUs Announced by AMD with April 11 Availability

Category: CPU's
Posted: March 16, 2017 08:37AM
Author: Guest_Jim_*


Two weeks ago AMD released its Ryzen 7 CPUs targeting more performance-hungry enthusiasts and now it has announced the mainstream-targeting Ryzen 5 processors at a press event in China. While the Ryzen 7 line consists only of 8-core/16-thread processors, Ryzen 5 has both 6-core/12-thread and 4-core/8-thread options. The two 6-core CPUs are the 1600X and 1600 with base/turbo clocks of 3.6/4.0 GHz and 3.2/3.6 GHz respectively. The 1600X has a TDP of 95 W and a price of $249 while the 1600 has a TDP of 65 W and a price of $219. The two 4-core/8-thread CPUs are the 1500X and 1400 with base/turbo clocks of 3.5/3.7 GHz and 3.2/3.4 GHz respectively. Both have a TDP of 65 W while the 1500X will be priced at $189 and the 1400 will cost $169. All four Ryzen 5 CPUs are to be available on April 11.

Like with the Ryzen 7 CPUs, not all of the Ryzen 5 processors will come with a cooler. The Ryzen 5 1600X will be without a cooler while the 1600 and 1500X will come with the Wraith Spire. The Ryzen 5 1400 will come with the Wraith Stealth cooler.

While looking at other sources we can find some other pieces, more technical pieces of information about the Ryzen 5 CPUs. For starters, all of them still use two CCX modules, like the 8-core Ryzen 7 CPUs, but with individual cores disabled. To maintain symmetry between the modules, the 6-core 1600X and 1600 have a 3+3 design, with one core disabled in both modules, and the 4-core 1500X and 1400 are both 2+2. Also the 20 ºC temperature offset AMD confirmed the other day is going to be present on the 95 W TDP 1600X, but not the three 65 W TDP processors.

AMD Releases Community Update on Several Ryzen CPU Concerns

Category: CPU's
Posted: March 14, 2017 09:58AM
Author: Guest_Jim_*

Since AMD released the Ryzen CPUs two weeks ago there have been a host of rumors and speculations trying to explain various issues reported in reviews and by people on the Internet. Now the company has released a statement on several of these concerns via a Ryzen community update.

The first topic tackled is if there is an issue with the Windows 10 thread scheduler, which is the part of the OS that decides what CPU core, physical or logical, runs a given thread, and is also what decides to shuffle threads around to other cores. There has been speculation the scheduler is degrading performance in some cases, but after investigating these claims AMD has concluded the thread scheduler is "operating properly for Zen" and the company does not believe there is an issue with the scheduler "utilizing the logical and physical configurations of the architecture." However it was also discovered that an outdated version of Sysinternals Coreinfo utility was producing incorrect topology data for Ryzen CPUs, but version 3.31 does provide correct results. Also, if you saw reports of significant performance differences between Windows 7 and Windows 10, AMD has concluded this is not related to scheduling differences but to the different software architectures of the operating systems.

The second topic addressed concerns temperature readings. Apparently the Ryzen 7 1700X and 1800X both carry a +20 ºC offset to the reported T Control (tCTL) temperature and the actual junction temperature. The purpose of the offset is to give all Ryzen processors a consistent fan policy, but it has also confused some temperature monitoring applications that failed to subtract the offset from the tCTL measurement. The Ryzen 7 1700 (non-X) is not affected by this as it does not have a tCTL offset.

AMD has also confirmed the recommendations to use the High Performance power plan offered in Windows 10. This turns off core parking, making idle CPU cores available for the thread scheduler and allows the CPU to alter its voltage and frequency states at the 1 ms intervals Ryzen supports, while Balanced may take longer as the software tries to participate in the power state changes. An update to optimize the power policy parameters for the Balanced plan is expected by the first week of April.

Finally, there have been reports of SMT (Simultaneous Multi-threading) reducing performance in some games. AMD's expectation is that games should generally see a neutral or positive benefit from SMT being enabled, and it has been tested in various titles. For those games that have been reported as performing worse, AMD suggests this indicates opportunities to improve the codebases of these games to better address the Zen architecture. Some simple changes have already been identified to improve how a game understands Zen's core/cache topology, and there should be a status update when these are ready.

A round of benchmarks for the upcoming NVIDIA GeForce GTX 1080 Ti have leaked on a Chinese website, with 3DMark tests being the focus. The posted benchmarks appear to have been run on an overclocked iteration of the card with a core clock of 2062MHz, from an estimated 1860MHz stock speed, and memory clock of 5702MHz. The scores posted showed significant improvements across three iterations of the Fire Strike test and one of Time Spy when compared to the GTX 1080 OC. The GTX 1080 Ti achieved scores of 31135 in Fire Strike (Perf.), 15093 in Fire Strike Extreme, 7362 in Fire Strike Ultra, and 10825 in Time Spy. The GTX 1080 was only able to manage scores of 23982 in Fire Strike (Perf.), 11457 in Fire Strike Extreme, 5708 in Fire Strike Ultra, and 7763 in Time Spy.

Author: Nick Harezga

AMD just made a big splash in the desktop CPU market with the release of the Ryzen 7 yesterday, and it has now announced the next additions to the Ryzen lineup. First up are the Ryzen 5 1500X and 1600X with four and six Zen cores, respectively. The 1500X will have a base clock of 3.5GHz and a boosted clock of 3.7GHz. The 1600X has a base clock of 3.6GHz and a boosted clock of 4.0GHz, giving it the same clocks with less cores as the 1800X. AMD didn't give exact pricing information on either chip, but did state that Ryzen 5 would cost between $199 and $299, making the 1600X a great alternative to the 1800X for users that don't need the extra cores. Further down the line is the Ryzen 3 which is expected to utilize four cores at a price below $200, putting it in competition with the Intel i3 lineup. Ryzen 5 chips are expected to be available between April and June of this year while Ryzen 3 is expected in the second half of the year.

Posted: March 2, 2017 04:19AM
Author: Nick Harezga

Today is the release date for the AMD Ryzen CPUs, and an embargo time on reviews of 9AM CT has users waiting a few more hours to see how the chips perform. However, for anyone unwilling to wait, Reddit user suet0604 had a pre-ordered Ryzen 7 1700X delivered early, and decided to post some benchmarks. The CPU was paired with an Asus Crosshair VI Hero motherboard, 16GB 3200MHz G.Skill DDR4, and a Radeon R9 390X. In the 720p version of the built-in CS:GO benchmark, the system was able to hit 289.91 fps, while an Intel i5 6600K running at 4.6GHz with a GeForce GTX 1070 only hit ~250 fps. The 1700X also performed well in the 3DMark Fire Strike benchmark with a score of 18,229, placing it a few thousand points ahead of the similarly priced i7 6800K, and also beating the leaked benchmark score for the 1700X. The 1700X also managed to top the i7 6900K in both the single and multi-threaded CPU-Z test with scores of 2159 vs. 1901 and 18298 vs. 13152, respectively. These numbers certainly bode well for the latest from AMD, and it will be interesting to see if the other benchmarks that arrive today paint a similar picture.

AMD Ryzen Overclocking Utility Pictured

Category: CPU's
Posted: February 23, 2017 02:04PM
Author: Guest_Jim_*

Yesterday AMD launched the new Ryzen R7 CPUs and since then the pre-orders have already placed all three R7 processors on Amazon's Best Sellers list for CPUs. Naturally more information than was officially shown off is coming out now, including a look at the AMD Ryzen Master overclocking utility from The Tech Chap.

First up, it appears each core can have its clock speed set individually, so if you want to dig in and optimize speeds on that level, it looks like you can. Curiously it appears the minimum speed the user can set is 3 GHz, apparently leaving lower speeds for when the CPU throttles down. The maximum speed is 6.375 GHz, which will probably take some extreme cooling. The user can also disable cores, with the image showing options of 0 (all cores being used), 2, 4, and 6. Just beneath that part of the UI we see the Voltage Control area where CPU Voltage, MEMO VDDIO, MEM VTT, and VDDCR SOC can all be set. Beneath that is where you can control the Memory settings, including the clock speed and the timings. Along the bottom of this page we see we can save profiles, with four already there and one marked 'C.'

My guess is that there is an entire other page of options to explore, as above where the cores are listed it says "Speed" and "Temperature." This is only my guessing, but I would expect that this is the Speed page and if you clocked on "Temperature" you would get another page with settings related to that. We will have to wait for embargoes to lift or the software to ship to know for sure though. In any case, I am sure many of us are interested in diving into these settings to see how far these new CPUs can be pushed.

Author: Guest_Jim_*

The day has finally come and AMD has launched its Ryzen 7 CPUs, based on the Zen microarchitecture that has been the focus of demoes, leaks, and rumors for quite a while now. Pre-orders are starting today at over 180 global etailers and boutique OEMs, with worldwide availability being March 2.

The Ryzen 7 line includes three processors: the 1800X; 1700X; and 1700. All three are 8-core, 16-thread CPUs. With higher numbers come higher specs and prices, with the Ryzen 7 1800X having a base clock of 3.6 GHz and boost clock of 4.0 GHz, but a TDP of 95 W and a price of $499. On the lower end, the Ryzen 7 1700 has a base clock of 3.0 GHz, a boost of 3.7 GHz, a TDP of 65 W, and a suggested price of $329. The Ryzen 7 1700X falls between these two, with a base clock of 3.4 GHz, boost of 3.8 GHz, TDP of 95 W, and a suggested price of $399.

Of these three, only the Ryzen 7 1700 comes with a cooler, the Wraith Spire, which should keep your CPU cool while only producing 32 dB of noise. AMD has also created the Wraith Stealth cooler, but it is not listed with the CPUs.

Along with these new CPUs are some 82 new motherboards based on the X370 and B350 chipsets from AMD. ASRock, Asus, Biostar, Gigabyte, and MSI are among the companies who designed these motherboards, and they are also expected to be widely available on March 2.

Now, here is the AMD Ryzen 7 Release video up on AMD's YouTube's channel:

AMD Ryzen 3DMark Scores Compare Favorably to Intel Counterparts

Category: CPU's
Posted: February 13, 2017 04:24PM
Author: Nick Harezga

The latest 3DMark benchmark leaks for the upcoming AMD Ryzen CPUs show that the chips can hold up against many of the latest Intel chips, despite being far cheaper. In the initial comparison, Videocardz compared the four, six, and eight core Ryzen models with numbers taken from Toms Hardware. The four core model held the lowest position on the chart with the six core just a few thousand points behind several Intel chips. The eight core model beat out all but the best Intel chips at a stock speed of 3.4 GHz, and fell just short of the Core i7 6950X when overclocked to 4.0 GHz. When compared to the official Futuremark score database, the overclocked eight core Ryzen beat the i7 6950X by about 500 points. On a per core basis, the eight core Ryzen outperforms the i7 6950X and the six and four core Ryzen perform even better. A number of Intel chips were able to convincingly beat the Ryzen chips on a per core basis, with the i7 7700K overclocked to 4.8 GHz reigning supreme. At a cost of $389 for the eight core Ryzen and $1700 for the i7 6950X, AMD can certainly offer a tremendous amount of bang for your buck.

Intel Atom C2000 CPUs Hit With Fatal Clock Flaw

Category: CPU's
Posted: February 7, 2017 04:54PM
Author: Nick Harezga

There are a number of indications that the Intel Atom C2000 family of system-on-chips have the potential to brick devices that use the chips. Intel CFO Robert Swan indicated in the Q4 2016 earnings call that "a product issue limited profitability during the quarter, forcing the biz to set aside a pot of cash to deal with the problem." Intel updated the documentation for the C2000 family last month with a description of a clock flaw characterized by Intel as "a degradation of a circuit element under high use conditions at a rate higher than Intel’s quality goals after multiple years of service." Last week, Cisco warned that a number of its products sold prior to November 16, 2016 "contain a faulty clock component that is likely to fail at an accelerated rate after 18 months of operation," and the affected systems utilize the C2000 family. A number of other manufacturers also utilize the chips, so be on the lookout if any of your devices that contain an Atom C2000 start acting up or stop working entirely.

AMD Possibly Launching Ryzen CPUs Before or During GDC

Category: CPU's
Posted: January 11, 2017 12:20PM
Author: Guest_Jim_*

This technically counts as a rumor currently, but it is possible AMD accidently let slip a release window for the upcoming Ryzen CPUs. Starting February 27 and going to March 3 is this year's Game Developer Conference (GDC) and naturally the event schedule is being put up online for attendees to make plans. One of the session being held at GDC is labeled "Optimizing for AMD Ryzen CPU," and in its original description it said "Join AMD Game Engineering team members for an introduction to the recently-launched AMD Ryzen CPU…" The description has since been revised if you look at the GDC webpage, but not before several people noticed and took screenshots of the original text.

If we assume the original version of the description was posted in error, but was not itself incorrect, that means we can expect the new line of CPUs to launch by the end of February, assuming they do not launch during GDC. If this leak is incorrect, then the latest information I have seen still is that Ryzen is still on schedule for a Q1 release, so we do not have too long to wait, either way.

AMD New Horizon Event Showed Off Ryzen CPU Technologies and Peak at Vega GPU Performance

Earlier today AMD held its New Horizon event, which was live-streamed for anyone interested in seeing the upcoming Zen-based CPUs being put to use, along with some new information about the new architecture. One of the announcements was that the name for the upcoming processors will be Ryzen. AMD also revealed SenseMI, which consists of multiple machine intelligence components to improve performance and efficiency. Following the Radeon Instinct announcement yesterday, we can clearly see AMD is trying to leverage this field.

The five SenseMI components are Pure Power, Precision Boost, Extended Frequency Range, Neural Net Prediction, and Smart Prefetch, and all of them will run in the background to optimize performance. Pure Power uses the over 100 sensors within the CPU to selectively reduce power consumption, based on the millivolt, milliwatt, and single-degree precision temperature measurements those sensor collect. Precision Boost is able to increase clock speeds by increments of 25 MHz, based on the task at hand and the measurements from those sensors, at it can do this at up to one thousand times a second. Extended Frequency Range allows Precision Boost to push the clock speed higher than the normal boost clock, if the cooling system has the headroom. Neural Net Prediction is an artificial intelligence neural network that analyzes what an application does so it can predict what pathways it will need in the future. Smart Prefetch fetches data it predicts will be needed ahead of when it is requested, like other prefetch systems but apparently with more sophisticated learning algorithms. No doubt helping these last two components is the combined 20 MB between the L2 and L3 caches.

Of course, the various new technologies and fancy marketing names are of little importance if the hardware cannot perform, so the Ryzen CPU with 8-cores and 16-threads, clocked at 3.4 GHz without any boost was pit against the Intel Core i7 6900K in a number of tests. The i7 6900K, which is also an 8-core/16-thread processor, was effectively off-the-shelf with the default base clock of 3.2 GHz and boost clock of 3.7 GHz enabled (though comments I have seen point out that in a multithreaded task, we might not see it boost) and was matched or beaten by the Ryzen CPU. These tests included rendering an image in Blender (and you can download the project from the New Horizon webpage), transcoding video with Handbrake, and playing Battlefield 1 at 4K resolution. For the gameplay, the CPUs were matched with a Pascal-based NVIDIA Titan X. By the way, the i7 6900K has a TDP of 140 W while the Ryzen CPU has a TDP of 95 W.

At the end of event some of the upcoming Star Wars Battlefront – Rogue One DLC was shown off, running at 4K and over 60 FPS using a Ryzen CPU and a Vega GPU. No specific information was given about the GPU, so that will have to wait for details on that.

The livestream is up on YouTube, and embedded below, for anyone who would like to watch it.

More Rumors, Including Pricing Leak for AMD Zen CPUs

Category: CPU's

Author: Guest_Jim_*

With AMD's new Zen CPU architecture set to be released in just months, it is only to be expected that more rumors start leaking out, covering performance, features, and pricing. Like any rumor though, none of this needs to be true, but it is still intriguing to hear about the Zen flagship CPU having a price of $499, while competing with or outperforming the $999 i7 5960X from Intel. This flagship is to be an 8-core CPU with 16 threads, and the latest engineering samples put it at a 3.2 GHz base clock and 3.5 GHz turbo clock. This is up from previous engineering samples, so we will see where the final product lands.

This will not be the only 8-core/16-thread Zen CPU though, with the next one down supposedly having a price of around $349. Naturally it will have lower clocks, supposedly a 3.0 GHz base and 3.2 GHz turbo. Both of these CPUs will be labeled SR7, indicating they are the highest performing of the series, while SR5 and SR3 labels are for lower-end Zen-based CPUs. These lower-end CPUs are to release some time after the SR7 chips.

The above rumors can all be found at WCCFtech but this next batch, and some more, can be found at the AMD subreddit. They include that because Zen is a System On a Chip (SOC) design, the BIOS or UEFI will be built into the CPU. That will require all overclocking to be done via the AMD Overdrive software, and therefore from within the operating system. It also means that a CPU will keep its settings when transferring it from one motherboard to another. AMD's Hyper Threading equivalent is called SMU and is supposed to be the as efficient as Intel's technology. There are some issues with the testing samples, and while a workaround exists, it is dragging down performance by 30-40%. Also it looks like bug fixing will continue right up until the chips are being sampled to partners.

Until Zen launches and makes its way into consumer computers, it is impossible to say how much of this information is true and how much is false. At least the wait will be over before too long.

AMD Announces New CPUs for Business Computers

Author: Nick Harezga

AMD has announced the seventh generation of its AMD Pro CPU for business computers. The AMD Pro combines a CPU and GPU into a single accelerated processing unit (APU), and was previously known as Bristol Ridge. If the name sounds familiar, that is because AMD has already used Bristol Ridge chips on the AM4 platform in laptop computers. The chips have support for up to four x86 Excavator cores, HSA compute acceleration, and DDR4. All of that translates into a CPU and GPU that are 17% and 88% faster, respectively, than an equivalent Intel i5. The AMD Pro will be available with speeds ranging from 3.8GHz to 4.2GHz with power consumption ranging from 35W to 65W.

Possible Intel i7-7700K Benchmarks Leak

Category: CPU's

Author: Guest_Jim_*

This is definitely something to take as a rumor, but that does not keep it from being interesting. It would seem that benchmarks of Intel's upcoming Cote i7-7700K, based on the company's 7th generation Kaby Lake architecture have leaked. According to the leak, this new CPU has made significant improvements in both single and multi-threaded performance compared to the current i7-6700K processor. The benchmark the data is from is Geekbench 4, and can be viewed here. In single-threaded performance, the 7700K scored 6131, and while scores for the 6700K vary, this puts it at around a 20% improvement for what I am seeing at the same benchmark database. Multi-threaded performance has also increased with the 6700K coming in around 16,000-17,000 points while the 7700K hit 20243, another roughly 20% improvement.

Of course these numbers are just rumors, so we will have to wait and see if they hold true. The i7-7700K CPU is a 4-core processor (8 threads, thanks to Hyperthreading) and for these tests was clocked at 4.2 GHz. It was also combined with a Gigabyte motherboard and 32 GB of RAM. It will be interesting to see how well the i7-7700K and all of the Kaby Lake processors perform, as they are to feature Intel's new 14 nm+ process technology, which is supposed to be an improvement over the company's current 14 nm process.

We are well into the final quarter of 2016, and we continue to be treated to advance information about coming products from AMD. Earlier this month we got the first glimpse into the AM4 socket and Vega 10 and 20 GPUs. The latest leak is focused on a future generation of CPUs known as Gray Hawk which appears to be next in line after Raven Ridge. Raven Ridge will use the 14nm process with a release expected sometime next year while Gray Hawk will use the 7nm process for a 2019 release. Gray Hawk will be paired with the Navi GPU architecture and will have four cores with eight threads and require only 10W of power.

7th Gen Core Processors Officially Announced by Intel

Category: CPU's
Posted: August 30, 2016 11:41AM
Author: Guest_Jim_*

Today Intel has officially announced its 7th generation, Kaby Lake, Core Processor Family, which features some potentially powerful improvements over the previous generation. Among these improvements is a change to the process technology, which Intel has dubbed 14 nm+ as it is supposed to be superior to the company's 14 nm technology. This change combined with CPU optimizations is expected to provide up to 12% improved performance in productivity (measured in SYSmark 2014) and up to 19% better web performance (measured in WebXPRT).

Of course such numbers are fair to take with a grain of salt, but the claims for better 4K UHD support are possibly more reliable. Intel has built in hardware acceleration for decoding VP9 and transcoding HEVC 10-bit codecs at 4K, which means it should be much more efficient to watch many 4K videos, such as those on YouTube, and encoding should be much faster too. This and other improvements are meant to help support what Intel calls the "immersive Internet." This is the idea that we are changing how we are using computers and are looking for ever more lifelike experiences, so superior 4K UHD support makes sense. The broader Thunderbolt 3 support these new processors can bring about may also help achieve this, at least for laptops as external graphics docks can be connected via this port, along with a 4K monitor.

Intel expects there to be over 100 different laptops and 2-in-1s powered by these processors available between September and the holiday season, thanks to the company's OEM partnerships.

MIT Developing Swarm Multi-core Architecture

Author: Nick Harezga

Processors with multiple cores are found in most systems these days, from PCs to smartphones. The use of multiple cores has helped to get around the limitations on processor speeds, but those extra cores don't translate into a direct increase in application performance. In order to take full advantage of the multiple cores, applications need to be written with parallel processing in mind, a complex task that many developers and applications don't bother with. Researchers at MIT have developed a new chip architecture, known as Swarm, to help alleviate some of the difficulties in taking advantage of parallel processing. In a test comparing a 64-core version of Swarm against highly-optimized parallel processing algorithms, Swarm outperformed the algorithms "offering three to 18 times faster processing. In its most impressive result, Swarm achieved results 75 times better than the regular chips, because that particular algorithm had failed to be parallelized on classic multi-core processors."

Author: Nick Harezga

A leaked Intel CPU roadmap obtained by Benchlife indicates that Intel will release a pair of "enthusiast" CPU families in the second quarter of 2017, Skylake-X and Kaby Lake-X. Both will use the 14nm manufacturing process with Skylake-X utilizing current architecture and Kaby Lake-X using one that has been optimized. Skylake-X was formerly known as Skylake-E and is expected to offer options of six, eight, and ten cores, similar to the current HEDT Broadwell-E CPUs. Kaby Lake-X CPUs will be the unlocked offering for this CPU family, with all Kaby Lake chips utilizing the Z270 chipset on the LGA 1151 socket.
