Intel Deep Learning Boost will also make its first appearance in the Cascade Lake products. In its first iteration, DL Boost will provide a vector neural network instruction set (VNNI) based on AVX-512 for faster inference acceleration. Intel is working to add VNNI to industry standard deep learning frameworks like TensorFlow and Caffe.

Next, in late 2019, we have the Cooper Lake architecture. Still based on 14nm technology, Cooper Lake will expand upon Intel DL Boost and add support for the BFloat16 data type, which provides the same level of precision as double precision (32-bit) floating points, but in a smaller (16-bit) data size. 

In 2020, after Cooper Lake, comes Ice Lake – the first 10nm-based Xeon. While details are sparse about what improvements Ice Lake will bring architecturally, Intel has said that it will be compatible with Cooper Lake platforms, giving users an upgrade path.

AMD Announces 2nd Generation Threadripper with up to 32 Cores

First teased at Computex earlier this summer, AMD has now released details and availability information for their 2nd Generation Threadripper CPUs.

18143522-R_Threadripper Metal_right.png

Based upon the same 12nm Zen+ architecture we saw with the Pinnacle Ridge CPUs like the R7 2700X, Threadripper will now be split into two product families, the X, and the WX series.

2gtr-news-2.PNG

The X-series is mostly a refresh of the Threaripper SKUs that we saw last year, with 12 and 16-core variants. The Threadripper 2920X and 2950X will retain the same two die, 4 CCX arrangement that we saw with the previous generation, with the ability to run in either unified or non-unified memory modes. 

Notably, the 8-core variant found in the original Threadripper lineup seems to be absent in the 2nd generation.

2gtr-news-3.PNG

This new generation of Threadripper comes in less expensive than the last, with a $50 price drop on the 12-core CPU, and a $100 price drop on the 16-core variant.

2gtr-news-4.PNG

The newest aspect of the 2nd Generation Threadripper Lineup is the addition of the "WX" series processors. These higher core count processors are being marketed by AMD more towards "Creators and Innovators" rather than gamers.

2gtr-news-5.PNG

Available in both 24 and 32-core variants, the Threadripper WX series represents the highest core count consumer CPUs ever launched. Since we know that Zen+ dies contain a maximum of 8 cores, we can assume that these processors are using a 4 die configuration, similar to the EPYC server parts, but likely with the same 64 lanes of PCIe and 4 channel memory controllers

This pricing is extremely aggressive compared to the highest core count competitor from Intel, the $2000 18-core i9-7980XE.

All 2nd Generation Threadripper CPUs will include the 2nd Generation Zen features that we saw in the R7 2600 and 2700 series, including XFR 2.0, StoreMI, and improved memory support and latency. 

Additionally, these new Threadripper CPUs will use the existing X399 chipset, with UEFI updates being made available for existing X399 boards, as well as some new variants such as the MSI MEG X399 Creation launching alongside the new CPUs.

specs-table.png

Availability of these processors is staggered, with the 32-core WX CPU shipping first on August 13th (and available now for preorder on Newegg and Amazon), followed shortly by the 16-core 2950X. However, we won't see the 12 and 24 variants until October.

Stay tuned for our review of these parts as they reach retail availability!

AMD builds semi-custom SoC with Zen and Vega for Chinese gaming market

Subject: Graphics Cards, Processors | August 3, 2018 - 04:41 PM |
Tagged: Zen, Vega, SoC, ryzen, China, APU, amd

This story originally appeared on ShroutResearch.com.

Continuing down the path with its semi-custom design division, AMD today announced a partnership with Chinese company Zhongshan Subor to design and build a new chip to be utilized for both a Chinese gaming PC and Chinese gaming console.

The chip itself will include a quad-core integration of the Zen processor supporting 8 threads at a clock speed of 3.0 GHz, no Turbo or XFR is included. The graphics portion is built around a Vega GPU with 24 Compute Units running at 1.3 GHz. Each CU has 64 stream processors giving the “Fenghuang” chip a total of 1536 SPs. That is the same size GPU used in the Kaby Lake-G Vega M GH part, but with a higher clock speed.

The memory system is also interesting as Zhongshan Subor has integrated 8GB of GDDR5 on a single package. (Update: AMD has clarified that this is a GDDR5 memory controller on package, and the memory itself is on the mainboard. Much more sensible.) This is different than how Intel integrated basically the same product from AMD as it utilized HBM2 memory. As far as I can see, this is the first time that an AMD-built SoC has utilized GDDR memory for both the GPU and CPU outside of the designs used for Microsoft and Sony.

ChinaJoy_2.jpg

This custom built product will still support AMD and Radeon-specific features like FreeSync, the Radeon Software suite, and next-gen architecture features like Rapid Packed Math. It is being built at GlobalFoundries.

Though there are differences in the apparent specs from the leaks that showed up online earlier in the year, they are pretty close. This story thought the custom SoC would include a 28 CU GPU and HBM2. Perhaps there is another chip design for a different customer pending or more likely there were competing integrations and the announced version won out due to cost efficiency.

Zhongshan Subor is a Chinese holding company that owns everything from retail stores to an education technology business. You might have heard its name in association with a gluttony of Super Famicom clones years back. I don’t expect this new console to have near the reach of an Xbox or PlayStation but with the size of the Chinese market, anything is possible if the content portfolio is there.

It is interesting that despite the aggressiveness of both Microsoft and Sony in the console space in regards to hardware upgrades this generation, this Chinese design will be the first to ship with a Zen-based APU, though it will lag behind the graphics performance of the Xbox One X (and probably PS4 Pro). Don’t be surprised if both major console players integrate a similar style of APU design with their next-generation products, pairing Zen with Vega.

Revenue for AMD from this arrangement is hard to predict but it does get an upfront fee from any semi-custom chip customer for the design and validation of the product. There is no commitment for a minimum chip purchase so AMD will see extended income only if the console and PC built around the APU succeeds.

Enthusiasts and PC builders have already started questioning whether this is the type of product that might make its way to the consumer. The truth is that the market for a high-performance, fully-integrated SoC like this is quite small, with DIY and SI (system integrator) markets preferring discrete components most of the time. If we remove the GDDR5 integration, which is one of the key specs that makes the “Fenghuang” chip so interesting and expensive, I’d bet the 24 CU GPU would be choked by standard DDR4/5 DRAM. For now, don’t hold out hope that AMD takes the engineering work of this Chinese gaming product and applies it to the general consumer market.

MSI Confirms Compatibility with Z370 Motherboards and Upcoming Intel CPUs

Hot on the heels on an Intel Roadmap leak yesterday that points to Intel's upcoming Coffee Lake refresh desktop processors launching as soon a Q3 2018, MSI today confirmed through a news post on their website that these new processors will retain compatibility with at least Z370 motherboards.

z370-9000series.jpg

The table posted by MSI contains the specific BIOS versions that add compatibility for these new processors for each Z370 motherboard in their lineup. There's no information about other existing Coffee Lake chipsets such as H370 and B360, but previous leaks have pointed towards these motherboards having some level of compatibility with new Intel processors.

The 9000-series is rumored to contain Intel's first 8-core consumer-oriented CPUs, in both non-hyperthreaded (i7-9700K), and hyperthreaded (i9-9900K) forms.

Banning Talos worship might be worth it, POWER9 still lags behind

Subject: Processors | July 6, 2018 - 03:16 PM |
Tagged: IBM, power9, talos 2, EPYC, xeon

Phoronix were recently given access to three servers running three different POWER9 Talos II configurations and compared them to EPYC and Xeon.  On paper these systems look amazing, thanks to the architecture supporting four threads per core; they tested  a dual 4-core Talos II system, a Talos II Lite with a single 22-core CPU and a Talos II with dual 18-core processors with thread counts of 32, 88, and 144 respectively. 

There were certainly usage scenarios where the dual 18 core system could outpace even the EPYC 7601 but could not surpass the dual Xeon Gold 6138 system.  The review covers a fair amount of benchmarks and configurations but doesn't begin to scratch the surface of wide variety of server configurations you need to consider before abandoning POWER9 altogether but the key metric, performance per dollar, shows these architecture solidly in the middle of the pack.

"Back in April we were able to run some IBM POWER9 benchmarks with remote access to the open-source friendly Talos II systems by Raptor Computer Systems. We were recently allowed remote access again to a few different configurations of this libre hardware with three different POWER9 processor combinations. Here are those latest benchmarks compared to Intel Xeon and AMD EPYC server processors."

Should you wait for the i9-8088K anniversary instead?

Now, before you decided to comment on Ken's i7-8086K article, consider he is not the only one who has encountered issues with Intel's Anniversary silicon.  The Tech Report offers succinct advice in their review as well "the i7-8086K isn't worth the $75 upcharge over the i7-8700K at stock speeds."  They manually overclocked the chip and found the same 5.1GHz limit, as the processors are thermally identical regardless of the handpicked artisan silicon inside the i7-8086K.  The 5GHz stock speed advertised does not seem to be available right out of the box but instead requires a bit of work.

On the other hand, if you like the idea of an Anniversary model CPU and would enjoy manually overclocking, the extra $75 might mean very little to you.

Der8auer is at it again, this time pushing Intel's Anniversary Edition i7-8086K quickly passing 7GHz in initial overclocking, showing just how well picked these Core i7-8700K's are.  He pushed the core voltage up past 1.85V and used an impressive amount of LN to accomplish this feat but he feels there is more to this processor.  Having had more time to work on overclocking 8700K's he has successfully pushed them to 7.3GHz, so in theory the 8086K should be able to beat that.  Take a look at the video posted on the Inquirer to see this happen.

Zen 2 "Rome" EPYC CPU on 7nm on track for 2018 sampling, 2019 release

Subject: Processors | June 5, 2018 - 11:22 PM |
Tagged: Zen 2, Zen, rome, amd

The first whiffs of Zen 2 are finally reaching us. During the AMD press conference at Computex today CEO Dr. Lisa Su stood on stage and held up the first public showing of Rome, the codename for AMD’s next-generation EPYC enterprise processor family.

amd19.png

Rome is exciting because it will be the first 7nm high-performance processor in the market, and it makes the 10nm production problems that Intel is having all the more troublesome for the blue-chip giant. And because Rome will be socket compatible with the currently shipping EPYC systems, there is a huge potential for market penetration through 2019.

AMD stated that it would be sampling Rome-based Zen 2 processors to partners in the second half of 2018, with launch in 2019. AMD does have silicon back in the labs, up and running. No more timing detail was given than that.

amd20.png

The competitive statement of AMD putting timeframes on its 7nm server processors, rumored to be going up to 64-cores PER SOCKET, while Intel struggles with its move to 10nm, is significant. AMD still targets a 5% market share for server processors by the end of the year, but it might be 2019 that proves to be a more significant year for the company’s drive back into the server space.

Computex 2018: AMD previews 32-core Threadripper CPUs for Q3

Subject: Processors | June 5, 2018 - 11:03 PM |

During the keynote address at Computex in Taipei, AMD SVP Jim Anderson was on stage to showcase a preview of the upcoming 2000-series of Threadripper processors for high-end consumer PCs. The Threadripper brand already made waves last year by bringing 16-core and 32-thread designs to the market for the very first time, improving performance for extreme productivity tasks, rendering, development, video, and more.

We knew that the 2000-series was coming this year, based on the 12nm process from GlobalFoundries, just as the Ryzen 2000-series uses, but we have narrowed the availability time frame to Q3 of 2018.

But the big story at the show was that this generation would see a doubling of the maximum core count on Threadripper. Yes, you will be able to buy 32-core and 64-thread AMD Threadripper CPUs later this year!!

Hot on the heels of the impressive, but dubiously cooled, Intel 28-core demo yesterday, AMD is clearly intent on continuing momentum that is has built throughout 2017. AMD didn’t show us any Cinebench numbers, but my understanding is that the demo provided was completely air cooled. Intel’s…not so much. While impressive to see 28-cores at 5 GHz yesterday, more impressive is a 32-core machine with a system design I would be willing to implement.

No more details on pricing, performance, or platform were made available during the keynote, but we’ll be asking those questions as the week progresses.

Computex 2018: Intel demos 28-core processor at 5 GHz

Subject: Processors | June 5, 2018 - 11:40 AM |
Tagged: X399, X-Series, Intel, HEDT, 28 core

If you thought running at 5 GHz was neat with a 6-core part, Intel had another surprise for you last night. As part of its Computex keynote, the company demonstrated a 28-core processor running at 5 GHz on all cores, planned for the HEDT segment sometime before the end of 2018.

We don't have a lot of detail on this demo, including what socket this is using, whether this is a single monolithic die design or a multi-chip package using EMIB, or if this is will cost you more than your current domicile to purchase.

It showed a score of 7334 on Cinebench R15. Think about that - the 18-core Core i9-7980XE is our current stock leader in this test with a result of 3346. That means this 28-core processor demo was 2.19x faster than the current fastest part on the market!! 

intel28corecb.jpg

All of the unknown factors make it slightly less exciting, to be honest. What power draw was it running at? Is this viable for a consumer platform, in reality? Is 5 GHz a possibility for us mere mortals? Clearly if you are in need of extreme multi-threading capability and performance for rendering, encoding, or mega-tasking, it appears Intel may have the best solution available come this holiday season.

UPDATE 6/6/18: It has now been confirmed by people on the ground in Taipei that the Intel 28-core demo was a complex feat. The motherboards were built by ASUS and Gigabyte, modifications of a server-class LGA3647 socket board that required a 32-phase power system, and a 1HP (horsepower) water chiller and refrigerant to drop the liquid to a cool 4 degrees Celsius. The processor is a single-die part, basically a Xeon Scalable Platinum 8180, that has a list price of $10,000.

Obviously this is not a configuration that any reasonable consumer, even the crazy ones really, would be willing to employ. It means motherboards with the X299 chipset will not be compatible with this part as it requires a new socket. It also means that clock speeds for real-world designs will be much lower, likely a Gigahertz or more. 

There are a lot of questions to poke around about before the end of the year if we are truly going to understand Intel's plans for the enthusiast platform at the end of 2018.

It should come as no real surprise to those of you that read PC Perspective, but Intel officially unveiled the new Core i7-8086K processor during its keynote last night in Taipei at Computex. The specs are right in line with expectations, offering a 6-core / 12-thread chip with a peak Turbo clock speed of 5.0 GHz.

Full Intel Ark Listing

The Core i7-8086K is a limited edition part with just 50,000 expected to be built, in celebration of the company's 50th anniversary and the 40th anniversary of the original Intel 8086 x86 processor. Pricing hasn't been released, but Intel is running a sweepstakes to give away 8,086 of the CPUs and it lists $425 as the value in the fine print, so that seems like a good guess.

8080k.png

The 300 MHz increases in base and Turbo clock speeds is impressive while sitting inside the same 95 watt TDP. We are eager to get one in for testing ourselves and see how that works in practice, though the limited edition nature of the part makes it a bit less interesting in the long run. (We were considering moving our GPU testbed to this for example, but using a part that may not be available for replication of our data in the future seems like a bad idea.)

I am sure many were hoping this limited edition part would be, or would be in addition to, an 8-core processor launch at Computex, but it doesn't appear that is in the cards.

The 40th anniversary of the original Intel 8086 microprocessor launch is just days away (June 8), and ahead of this VideoCardz.com has posted screen captures of online listings for the rumored 8086 anniversary CPU - the Core i7-8086K.

(Screen captures above sourced from VideoCardz.com)

From VideoCardz.com:

"Some retailers have already started listing the new SKU on their websites, indicating 70 USD/EUR premium over i7-8700K (~480/470 EUR). Not much is known at this point, but the CPU is rumored to be 5.0 GHz chip out of the box. It is, however, still expected to be a 6-core SKU."

Beyond the online retailer listings accidentally posted early, presumably, not much is known; though it seems fair to conclude that this may indeed be a higher-clocked version of the current i7-8700K and would therefore remain a 6-core/12-thread product. Intel is going to be at Computex beginning June 5 where they "will showcase how the company is powering the future of computing" so might we hear an announcement of a new product on the eve of the 8086 anniversary? The possibility is too logical to ignore.

Spectre 3a and Spectre 4 Unfortunately Announced...

Tagged: x86, arm, Intel, amd, spectre

Security researchers at Microsoft and Google have found two new vulnerabilities along the lines of the Spectre and Meltdown bugs from early January. These are being called Spectre 3a (Rogue System Register Read) and Spectre 4 (Speculative Store Bypass). Like last time, hardware and software vendors have addressed the issues, which will be coming down via OS updates.

bond-2018-spectre-joke.jpg

Naturally, James Bond will steal information when there's Intel Inside.

On the AMD side of things, they claim that the Spectre 4 vulnerability will be patched as far back as Bulldozer (2011). They also claim that no action will be necessary, at least to their knowledge, for Spectre 3a on their x86 parts. They have also released a short, five-page whitepaper discussing the issue.

On the Intel side of things… a security bulletin has been posted for CPUs as far back as Nehalem. They don’t exactly clarify which processors are susceptible to which vulnerabilities, but they acknowledge that both Spectre 3a and Spectre 4 touch something on their product stack to some extent. They have submitted a beta microcode update to OS vendors, which they expect to be production ready “in the coming weeks”.

ARM is also affected to some extent. They have published a table that lists which architectures are vulnerable to what exploit. Interestingly, there are some processors that are vulnerable to 3a, but not 4, and others that are vulnerable to 4, but not 3a (and, of course, some that are vulnerable to both and neither). Since these exploits are based on optimizations gone awry, you would think that it would have built up over time, but that doesn’t seem to be the case. The only pattern I could notice is that Variant 4 only affects newish 64-bit ARM processors. I don’t know if that’s a red herring, or a well-known corollary of the bug that I just don’t know enough about, but it’s about all that I can see.

Regardless, expect patches soon, which might, again, lower performance by some amount.

AMD Releases Updated Raven Ridge Desktop APU Graphics Drivers

Today, AMD released the first driver update for the desktop Raven Ridge APUs since their launch in February of this year.

The new Q2 2018 drivers are based on AMD's current Radeon Software Adrenalin Edition release and bring features such as ReLive and the Radeon overlay to the Vega-powered desktop platform.

adrenalin-74.jpg

We haven't had a lot of time to look for potential performance enhancements this driver brings yet, but we did do a quick 3DMark run on our Ryzen 5 2400G with memory running at DDR4-3200.

3dmark-fs.png

Here, we see healthy gains of around 5% in 3DMark Firestrike for the new driver. While I wouldn't expect big gains for older titles, newer titles that have come out since the initial Raven Ridge drive release in February will see the biggest gains.

We are still eager to see the mobile iterations of AMD's Raven Ridge processors get updated drivers, as notebooks such as the HP Envy X360 have not been updated since they launched in November of last year.

It's good to see progress from AMD on this front, but they must work harder to unify the graphics drivers of their APU products into the mainstream graphics driver releases if they want those products to be taken seriously as gaming options.

Two scoops of Ryzen, eat on the go or at your desk

AMD have extended both their processor lineup as well as their names, by sticking Pro into the already verbose Ryzen 2 series, and added another letter to pay attention to as well.   The 2xxxU series are mobile APUs which you won't see running around in the wild, the 2xxxG desktop series you certainly will, however there is also an E you need to pay attention to. 

The Ryzen 5 Pro 2400G is a 65W part which will offer four multi-threaded cores topping out at 3.9GHz, with 11 Vega CUs and ships with the Wraith Stealth cooler. The Ryzen 5 Pro 2400GE is almost as similar as the name but tops out at 3.8GHz, also has 11 Vega CUs and sports an impressive TDP of 35W, which may be part of the reason why it doesn't ship with a cooler. 

The series looks to offer a great choice for someone building a machine without a GPU installed, whether they intend to add one at a later time or not.  The naming conventions being used by Intel and AMD are getting far too easy to confuse already, without adding possible confusion within single product lines.  Let's hope this does not continue for too long.  The Inquirer lists all the models, mobile and desktop, on this page.

Whether you have had a chance to play around with a new Ryzen processor or not, you might benefit from more information on what XFR2 and Precision Boost 2 are and what they are not.  [H]ard|OCP spent some time to write an article that dispels the rumours which have been spread, especially the fact that these are both unreleased at the moment.  Together they will provide support for Precision Boost Overdrive, which could be supported by Ryzen Zen+ CPUs on an X470 motherboard, at least in theory.  When enabled it will utilize the ability of the new Ryzen Master software to monitor your motherboards VRM usage and if it sees it is below it capacity it will relax the vCore limiter on your CPU allowing more juice to flow in which can be used to increase the frequency of your Zen + chip.  It will be interesting to see how effective this is, but for now all we can do is read about it.

"We wanted to put together a quick overview about what Precision Boost 2 and XFR2 are NOT about. It seems that slides leaked, and faked, earlier in the 2nd generation Ryzen's development have clouded some people's understanding on what features are included, but more important which features are not."

Microsoft releases 64-bit SDK for Windows on Arm platforms

During the Microsoft BUILD developer conference, the Windows initiative for Qualcomm and Arm processors got a much needed shot in the arm (heh) with announced support for a 64-bit SDK.

Visual Studio 15.8 Preview 1 contains the early version of these tools that will give developers the ability to build native 64-bit Arm apps. Microsoft claims that this “represents the next step in the evolution of the Always Connected PC running Windows 10 on ARM” and I couldn’t agree more.

This gives software developers the ability to target Arm-based processors like the Snapdragon 835 from Qualcomm natively without forcing users to depend on emulation layers provided by Microsoft. While the emulation layer is critical for compatibility, it does slow performance quite a bit compared to native-running code.

While the Windows Store already supports ARM32 packages, ARM64 packages will be supported “soon” based on what Microsoft is telling us. Even more interesting, Microsoft is promoting the ability for developers to post the Win32 (non-Store) ARM64 version of software online, rather than waiting for the Store apps to be approved.

The Microsoft website has details on how developers can start this integration. Qualcomm has its own documentation as well.

From my own view, this a necessary step for Microsoft to take, even if it does seem later than many would have liked. The benefits of Windows 10 running on Snapdragon and Arm are real and substantial, but being hindered by performance due to emulation was always known to be a speedbump. Getting developers access to better, and easier to use, Arm compilation is the next step.

I would also like to see Microsoft take a more proactive role in pushing developers to offer both versions of software. MS simply cannot take a passive, backseat approach to the Always On, Always Connected PC initiative and have it be a success.

Intel Kicks Kaby Lake-X CPUs to the Curb

So, do you remember the Kaby Lake-X processors that launched along side the Skylake-X parts back on June 19, 2017. These are (were) 14nm+ processors built into the LGA2066 socket as a part of the X299 chipset launch. They shipped as the Core i7-7740X (4-core, 8-thread) and Core i5-7640X (4-core, 4-thread) and at the time I had this to say about them:

These are very…interesting CPUs. They do not offer new features compared to the Core i7-7700K or Core i5-7600K, but run at barely higher clocks (100 MHz on the base on the 7740X for example). They don’t see more PCIe integration, they don’t have larger caches. They are basically the same Kaby Lake design we have come to know previously but in a new package and prepped for a new set of motherboards. Is that an advantage? It’s hard to know yet, but in general, the X299 motherboard market is going to be more expensive than the Z270 motherboard market, meaning you are going to pay more in total to own this CPU. Does the added TDP give us more thermal headroom for overclocking? Maybe the new heat spreader? I’m not sure and Intel hasn’t said yet. But what they have stated is that they wanted to offer the option to consumers that wanted the “absolute fastest gaming processor” with the best clock speeds at a reasonable price.

Even in June, the value and positioning of the Kaby Lake-X processor was a mystery. Well Intel has fixed all of that today by announced end-of-life for both of those processors.

Intel's language in the release is kind of interesting: "Market demand for the products listed in the "Products Affected/Intel Ordering Codes" tables below have shifted to other Intel products." Yeah, I bet it has. 

These were parts without a real audience, and their creation was a consistent mystery to the enthusiast market Intel targeted. For many, it was a honest sign that Intel has lost track of what the PC market was asking for. At least the short lifespan of the pair indicates that Intel got the message loud and clear.

If you are so inclined, you can still pick up the 7740X and 7640X for a while longer. Here is the table of Kaby Lake-X's remaining life.

The number of good game streamers is Ryzen

The Tech Report tested the gaming prowess of the new Ryzen 2 chips in a variety of games at 1080p; as the 1080 Ti they used in all the test systems equalled the playing field so that the CPU performance could been seen.  If you game at higher resolutions, then the performance delta is moot as it is your GPU which is handling the load but at 1080p gaming, CPU and DDR frequency matters.  While the new chips did not manage to surpass Intel's they closed the gap noticeably compared to the initial generation of Ryzens and they were capable of doing something Intel's offerings simply can't.  Those who like to stream their games while they play would do well to consider the Ryzen 7 2700X and Ryzen 7 1800X as they offered a significantly better experience and were the only ones capable of a decent stream of the latest Deus Ex game.
