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."

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.

Author: Nick Harezga

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.

AMD Ryzen Benchmarks Posted Ahead of Release

Category: CPU's
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

Category: CPU's

Author: Guest_Jim_*

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
Posted: November 28, 2016 10:56AM
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.

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

Posted: July 6, 2016 04:10PM
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

Apollo Lake is the "next-generation family of Atom-based notebook SoCs" from Intel, built on the x86 microarchitecture known as Goldmont. Also built in to the new chips is the graphics core found in Skylake processors with support for DDR4, DDR3L, and LPDDR3/DDR4. Intel envisions that Apollo Lake will make a great choice for a variety of low power or small form factor systems including notebooks, tablets, and all-in-one systems. In order to help accommodate these smaller devices, Intel has provided a list of recommendations to help with size and power restrictions including M.2 SSDs and Wi-Fi that is soldered to the motherboard. More information is expected to become available in the near future, with Computex likely a safe bet.

Intel Moving Away From Tick-Tock Release Schedule

Author: Nick Harezga

Intel has followed a tick-tock release strategy for as long as I can remember, wherein the company released a "new lithographic process note in one product cycle (a ‘tick’) and then an upgraded microarchitecture the next product cycle (a ‘tock’)." It was revealed about a week ago that the upcoming Kaby Lake architecture would be a second "tock" in the current release cycle rather than the "tick" in the next cycle. Decreasing transistor size has forced Intel to reevaluate this strategy, which is now being referred to as the Process-Architecture-Optimization cycle. It looks like Intel will be utilizing this strategy going forward rather than treating it as more of a one-off occurrence. From a consumer perspective this means that we will have to wait longer between brand new architectures and smaller transistors. Hopefully the optimization stage of the cycle will offer enough of an improvement to keep us upgrading.

10nm Intel Cannonlake Arriving Late Next Year

Intel has confirmed its plans to release 10nm Cannonlake based processors in the second half of 2017 to investing site The Motley Fool. This has been the rumored time frame for a few months, but a job posting discovered by the Fool led to some speculation that Intel would have difficulty meeting the deadline, pushing the release back to 2018. For some time Intel has been releasing CPUs in a Tick-Tock format, wherein the company "would release a Tick, a new (smaller) process node which will be using an existing architecture with minor updates and that would be followed by a Tock, a brand new microarchitecture built upon an existing process node." The constant push for smaller transistors has altered this schedule, causing Intel to add a third Tock with a minor update to a current microarchitecture. The upcoming 14nm Kaby Lake CPUs represent the third Tock and Cannonlake opening the next cycle as the Tick.

Non-K Skylake CPUs Can No Longer be Overclocked Due to CPU Microcode Update

Category: CPU's
Posted: February 9, 2016 04:34PM
Author: Brentt Moore

In July of last year, it was reported that Skylake processors from Intel that were not a part of the K-series would be able to be overclocked due to changes made by motherboard manufacturers. Then, in December of last year, ASRock released a BIOS update that enabled overclocking for Intel Skylake CPUs that were not marketed as being overclockable. Now, Intel has pushed an official CPU microcode update to various motherboard partners that unfortunately disables the ability for customers to overclock their non-K series Skylake processors. An Intel spokesman noted that "The latest update provided to partners includes, among other things, code that aligns with the position that we do not recommend overclocking processors that have not been designed to do so." The spokesman went on to say that "Additionally, Intel does not warranty the operation of the processor beyond its specifications."

Fortunately for consumers, the CPU microcode update that disables the ability for Intel Skylake processors that are not a part of the K-series to be overclocked will only make its way onto motherboards with a BIOS update. So, in short, consumers can still overclock their non-K series Skylake processors as long as they continue to utilize the BIOS update that enabled the feature in the first place.

The Intel Core i7-6700K is the "flagship" processor of the Skylake architecture with a base speed of 4GHz, but the base speed is never enough for some people. Overclocker Chi-Kui Lam managed to achieve a clock speed of 7025.66MHz, breaking the record for highest clock speed on the new architecture, but falling short of the highest clock speed of 8722.78MHz, obtained using an AMD FX-8370. Lam paired the CPU with an ASRock motherboard, G.SKILL memory, a 1300W Antec power supply, and liquid nitrogen cooling. In addition to the ultra low temperature cooling provided by the liquid nitrogen, Lam also chose to disable all but one core to give the best chance of achieving high clock speeds.

Rumors Say Intel to Launch 5.1 GHz Xeon CPU for Limited Customers

As always, rumors should be taken with a grain of salt, and as this one likely will not affect consumers, it may not matter too much if it is true or not. Supposedly Intel is going to be launching its E5-2600 V4 Xeon family of CPUs with one processor having a default clock of 5.1 GHz. According to the rumor, its model number is E5-2602 V4 and will be a quadcore chip with 10 MB of L3 cache and a TDP of 165 W.

If you are thinking that this could be a fun processor to upgrade to, if the rumor is true, there is more to the rumor that may disappoint you. The CPU is not destined for the consumer market and might even be limited to a specific customer, the NSA. Even if the processor does exist, there is a good chance it would never come to the consumer market.
