In a move that would seem to contradict what we have heard about Intel's new 28-core Xeon W-3175X processor, Newegg currently has it listed as a standalone CPU part for $2977.99.

The official announcement from Intel had only mentioned availability via pre-built workstations from system integrators:

"How You Get It: The Intel Xeon W-3175X processor is available from system integrators that develop purpose-built desktop workstations."

Though not available for purchase (yet?), the existence of this product entry in Newegg's system suggests that the DIY community will have access to Intel's most powerful workstation processor after all, and without a markup over the tray price.

Here is a look at the specs from Intel:

  • Base Clock Speed: 3.1 GHz
  • Maximum Single Core Turbo Frequency: 4.3 GHz
  • Cores/Threads: 28/56
  • TDP: 255W
  • Intel Smart Cache: 38.5 MB
  • Unlocked: Yes
  • Platform PCIE Lanes: Up to 68
  • Memory Support: Six Channels, DDR4-2666
  • Standard RAS Support: Yes
  • ECC Support: Yes
  • RCP Pricing (USD 1K): $2,999

This unlocked 28-core/56-thread CPU offers a base clock speed of 3.1 GHz and Turbo of up to 4.3 GHz (single-thread), and that level of performance comes with a 255-watt TDP. In fact a special cooler from Asetek was also announced today which was developed with Intel for this CPU.

And while a $3000 price tag is obviously not going to drive this into mainstream adoption, this processor only being offered through system integrators at this time, and is aimed at the high-end workstation segment. As to performance, there are some day-one reviews out there from GamersNexus, AnandTech, and PC World, among others, and the consensus seems to be that this is an impressive performer, with particular workload the key to performance relative to competing options such as AMD's Threadripper 2990WX (which currently sells for $1730).

We don't have the answers yet about about total platform costs with motherboard pricing currently an unknown, and (more importantly) system integrators the only way to obtain it, but performance in Adobe CS applications alone will likely make this attractive to content creators at the very least.

Intel Unveils Next-Gen Sunny Cove CPU, Gen11 Graphics, and 3D Stacking Technology

Subject: Processors | December 12, 2018 - 09:00 AM |
Tagged: xeon, Sunny Cove, processor, intel core, Intel, integrated graphics, iGPU, Foveros, cpu, 3D stacking

Intel’s Architecture Day was held yesterday and brought announcements of three new technologies. Intel shared details of a new 3D stacking technology for logic chips, a brand new CPU architecture for desktop and server, and some surprising developments on the iGPU front. Oh, and they mentioned that whole discrete GPU thing…

3D Stacking for Logic Chips

First we have Foveros, a new 3D packaging technology that follows Intel’s previous EMIB (Embedded Multi-die Interconnect Bridge) 2D packaging technology and enables die-stacking of high-performance logic chips for the first time.

2d-and-3d-packaging-drive-new-design-flexibility.jpg

“Foveros paves the way for devices and systems combining high-performance, high-density and low-power silicon process technologies. Foveros is expected to extend die stacking beyond traditional passive interposers and stacked memory to high-performance logic, such as CPU, graphics and AI processors for the first time.”

Foveros will allow for a new “chiplet” paradigm, as “I/O, SRAM, and power delivery circuits can be fabricated in a base die and high-performance logic chiplets are stacked on top”. This new approach would permit design elements to be “mixed and matched”, and allow new device form-factors to be realized as products can be broken up into these smaller chiplets.

The first range of products using this technology are expected to launch in the second half of 2019, beginning with a product that Intel states “will combine a high-performance 10nm compute-stacked chiplet with a low-power 22FFL base die,” which Intel says “will enable the combination of world-class performance and power efficiency in a small form factor”.

Intel Sunny Cove Processors - Coming Late 2019

Next up is the announcement of a brand new CPU architecture with Sunny Cove, which will be the basis of Intel’s next generation Core and Xeon processors in 2019. No mention of 10nm was made, so it is unclear if Intel’s planned transition from 14nm is happening with this launch (the last Xeon roadmap showed a 10 nm transition with "Ice Lake" in 2020).

Intel_CPUs.jpg

Intel states that Sonny Cove is “designed to increase performance per clock and power efficiency for general purpose computing tasks” with new features included “to accelerate special purpose computing tasks like AI and cryptography”.

Intel provided this list of Sunny Cove’s features:

  • Enhanced microarchitecture to execute more operations in parallel.
  • New algorithms to reduce latency.
  • Increased size of key buffers and caches to optimize data-centric workloads.
  • Architectural extensions for specific use cases and algorithms. For example, new performance-boosting instructions for cryptography, such as vector AES and SHA-NI,  and other critical use cases like compression and decompression.

Integrated Graphics with 2x Performance

Intel did reveal next-gen graphics, though it was a new generation of the company’s integrated graphics announced at the event. The update is nonetheless significant, with the upcoming Gen11 integrated GPU “expected to double the computing performance-per-clock compared to Intel Gen9 graphics” thanks to a huge increase in Execution Units, from 24 EUs with Gen9 to 64 EUs with Gen11. This will provide “>1 TFLOPS performance capability”, according to Intel, who states that the new Gen11 graphics are also expected to feature advanced media encode/decode, supporting “4K video streams and 8K content creation in constrained power envelopes”.

And finally, though hardly a footnote, the new Gen11 graphics will feature Intel Adaptive Sync technology, which was a rumored feature of upcoming discrete GPU products from Intel.

Discrete GPUs?

And now for that little part about discrete graphics: At the event Intel simply “reaffirmed its plan to introduce a discrete graphics processor by 2020”. Nothing new here, and this obviously means that we won’t be seeing a new discrete GPU from Intel in 2019 - though the beefed-up Gen11 graphics should provide a much needed boost to Intel’s graphics offering when Sonny Cove launches “late next year”.

Intel unveils Xeon Cascade Lake Advanced Performance Platform

Subject: Processors | November 5, 2018 - 02:00 AM |
Tagged: xeon e-2100, xeon, MCP, Intel, Infinity Fabric, EPYC, cxl-ap, cascade lake, amd, advanced performance

Ahead of the Supercomputing conference next week, Intel has announced a new market segment for Xeons called Cascade Lake Advanced Platform (CXL-AP). This represents a new, higher core count option in the Xeon Scalable family, which currently tops out at 28 cores. 

cxl-ap.png

Through the use of a multi-chip package (MCP), Intel will now be able to offer up to 48-cores, with 12 DDR4 memory channels per socket. Cascade Lake AP is being targeted at dual socket systems bringing the total core count up to 96-cores.

UPI.jpg

Intel's Ultra Path Interconnect (UPI), introduced in Skylake-EP for multi-socket communication, is used to connect both the MCP packages on a single processor together, as well as the two processors in a 2S configuration. 

Given the relative amount of shade that Intel has thrown towards AMD's multi-die design with Epyc, calling it "glued-together," this move to an MCP for a high-end Xeon offering will garner some attention.

When asked about this, Intel says that the issues they previously pointed out with aren't inherently because it's a multi-die design, but rather the quality of the interconnect. By utilizing UPI for the interconnect, Intel claims their MCP design will provide performance consistency not found in other solutions. They were also quick to point out that this is not their first Xeon design utilizing multiple packages.

Intel provided some performance claims against the current 32-core Epyc 7601, of up to 3.4X greater performance in Linpack, and up to 1.3x in Stream Triad.

As usual, whether or not these claims are validated will come down to external testing when people have these new Cascade Lake AP processors in-hand, which is set to be in the first half of 2019.

More details on the entire Cascade Lake family, including Cascade Lake AP, are set to come at next week's Supercomputing conference, so stay tuned for more information as it becomes available!

Intel unveils updated X-Series HEDT processors, 28-core Xeon for Workstations

Subject: Processors | October 8, 2018 - 11:14 AM |
Tagged: xeon w-3175x, xeon, x299, Intel, i9-9890xe, C621, 9th generation, 28-core

Consumer processors weren't the only Intel products to see an update today, as Intel announced updates to their HEDT lineup, as well as a new platform for their 28-core processor previously announced at Computex.

IMG_3454.png

First is the Xeon W-3175X, which readers will remember from the now infamous Intel demonstration at Computex, featuring a 5 GHz overclock achieved through the use of a 1HP water chiller.

Today we were introduced to the final product iteration of this 28-core demo, the Xeon W-3175X. Utilizing the same C621 chipset, this processor is essentially a Xeon Platinum 8180 which launched in late 2017 but with an unlocked multiplier and running at higher clock speeds.

IMG_6896.JPG

The Xeon W-3175X provides a 600 MHz base clock and a 500 MHz Turbo Boost 2.0 clock advantage over the Xeon Platinum 8180. Along with these clock speed increases comes a TDP increase to 255W, compared to the 205W TDP of the Xeon 8180.

Additionally, Xeon W-3175X will support the same six-channel ECC memory configuration as the Xeon Platinum 8180. Similarly, the Xeon W-3175X will use the LGA3647 socket, currently only found on the Xeon Scalable family of processors.

Given that current lack of LGA3647-based workstation motherboards and the TDP increase over the Xeon Scalable processor, this new Xeon-W part will mean the release of all-new motherboards, a sneak peak of which we saw at Computex. ASUS and Gigabyte are said to be the launch partners, with motherboard options to be available in December alongside the processor.

IMG_8760.png

On the slightly more reasonable side, we have the refresh of Intel's X-series HEDT processors.

IMG_5374.png

Topping off with the 18-core i9-9980XE, this lineup looks very familiar to Intel's current HEDT lineup, aside from some clock speed and core count increases.

Instead of starting at a 6-core, 12-thread configuration like the 7th generation, the 9th generation HEDT parts now start at the same 8-core, 16-thread configuration we see with the i9-9900K. Similarly, there are now two 10-core SKUs, the i9-9820X and i9-9900X.

Across the board, we see a 300-400 MHz increase on the base clocks of these new parts compared to the previous generation, as well as a 200-300 MHz to the Turbo Boost 2.0 clock speeds.

IMG_5456.png

The X-series processors will once again feature a soldered connection between the die and heatspreader for increased thermal performance.

These new X-series processors will continue to use the X299 platform, although we expect to see a few newly revised motherboards based on the X299 chipset from partners as we have for other HEDT launches.

While the new 9th generation consumer CPUs feature a combination of hardware, software, and microcode updates for side-channel attack vulnerabilities like Spectre and Meltdown, both the new X-series CPUs as well as the Xeon W-3175X only feature microcode and software fixes as detailed below:

  • Speculative side channel variant Spectre V2 (Branch Target Injection) = Microcode + Software
  • Speculative side channel variant Meltdown V3 (Rogue Data Cache Load) = Microcode
  • Speculative side channel variant Meltdown V3a (Rogue System Register Read) = Microcode
  • Speculative side channel variant V4 (Speculative Store Bypass) = Microcode + Software
  • Speculative side channel variant L1 Terminal Fault = Microcode + Software
IMG_4518.png
 
 
One of the points that Intel stressed this morning when announcing these new products is the importance of their Mesh architecture as compared to AMD's Infinity Fabric-based solution to core count scaling. 
 
IMG_5456.png
 
Intel claims the performance benefits that the unified memory architecture, where all cores can access memory, provides over the Threadripper 2990WX are significant in some applications including Autodesk Maya, Adobe Premiere Pro, and Unreal Engine build times.
 
In general, the announcements of these high-core count processors are relatively tame compared to the updates that Intel's consumer desktop CPUs saw today. AMD has been very aggressive with their second generation Threadripper processors in term of pricing and performance, so it will be interesting to see how these new Intel X-series processors change the HEDT market outlook.
 
As for the 28-core Xeon-W part, it seems odd for Intel to be launching a whole new desktop platform in-order to compete with the likes of the 24 and 32-core second generation Threadripper processors from AMD. 
 
The Xeon W-3175X will be available starting in December, while the new Intel X-series processors will be available in November.

The coming difficulties of getting Intel Inside your computer

Subject: General Tech | September 27, 2018 - 03:27 PM |
Tagged: Intel, xeon, supply shortage

Two different sources have confirmed there will be a shortage of Intel processors over the coming months, Novatch and Compal Electronics, with no clear end in sight.  This is not necessarily due to the difficulties they've encountered moving to a new fabrication node, but that certainly can't help.  Demand for Xeon processors has climbed quickly and Intel is scrambling to provide supply.  They do suggest they are focusing specifically on Xeon and Core processor production; one might point out that is the vast majority of their business and so of course they are.

This is a huge opportunity for AMD, the EPYC product line is in stock, less expensive and certainly capable of the level of performance that Enterprise requires, let alone SMBs.  A shortage of Core series also opens up an opportunity for system builders to start providing Ryzen based systems for consumers.  Their lower cost GPUs may also see a spike in sales in the coming months if the price of NVIDIA's RTX cards increase beyond their current level.

"In a warning to customers on Thursday, Novatech said that the shortage has been caused by high demand for Intel's Xeon data centre microprocessors, which Intel has chosen to prioritise over consumer and business PC demands."

Tagged: xeon, intel DL boost, Intel, ice lake, dcg, data centric, cooper lake, cascade lake

Today at Intel's Data Center Group's Data-Centric Innovation Summit, they provided a peek into the future of Xeon processors.

cascade-lake.jpg

Coming later this year are the oft-rumored Cascade Lake Xeons. In addition to supporting Optane DC Persistent memory, Cascade Lake will offer hardware-based mitigations for Spectre/Meltdown vulnerabilities.  

intel-dlboost.jpg

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.

xeon-roadmap.jpg

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.

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.

powerpc-1-thumb.jpg

"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."
