AMD Introduces Epyc Server Chip, 16-Core Desktop Chip

AMD Epyc

At this week’s monetary analyst assembly, AMD unveiled a 16-core, 32-thread desktop processor known as Ryzen Threadripper—its new Epyc model for server chips—and launched its first graphics board aimed on the machine studying market.

However I used to be additionally glad to see the corporate unveil a roadmap of successive generations in its CPU, GPU, and server traces, with migration to 7nm and 7nm+ course of nodes via 2020, which is essential for the agency to regain credibility with enterprise consumers. At this level, opponents Intel and Nvidia dominate their markets, significantly on the server aspect, and enterprise consumers have to be satisfied that AMD will probably be a long-term participant to ensure that it to land on the consideration record.

“Immersive and instinctive computing will remodel all of our day by day lives,” AMD CEO Lisa Su mentioned on the convention when defining the corporate’s imaginative and prescient for the long run. Immersive computing with high-end graphics is throughout us, however instinctive computing—which entails utilizing enormous quantities of information and machine studying algorithms—is simply starting to evolve. All of this requires “high-performance computing,” she mentioned, a time period she used to explain all kinds of high-end computing and graphics, not simply the HPC or supercomputing market.

Su talked at size about investing for “multi-generational management” in x86 CPUs, graphics for each PCs and built-in, and software program—a giant change for a corporation whose main merchandise have focused the mainstream or low-end markets. AMD will now give attention to premium merchandise, she mentioned, and famous that whereas the mainstream accounts for many of its items, the premium a part of the market accounts for many of its income and income.

Lisa Su with Epyc chip

Her largest announcement was in all probability Epyc, the branding for the brand new line of server chips, which had been codenamed Naples. Su mentioned that the Zen structure, which debuted in the Ryzen desktop chips was “created with the brand new knowledge middle in thoughts.” And whereas she is enthusiastic for what Zen can convey within the desktop and laptop computer markets, she is much more enthusiastic about what Zen can do within the knowledge middle market. She talked about how AMD has additionally focused the info middle market via Radeon Intuition, a model its next-generation graphics structure often called Vega—which can present 25 teraflops of efficiency—and the way these would work collectively in a imaginative and prescient of heterogeneous computing.

“In the present day’s knowledge middle actually requires heterogenous computing to achieve success,” she mentioned, describing AMD as the one supplier of each high-performance computing and graphics.

AMD's Mark Papermaster

CTO Mark Papermaster gave extra element concerning the glue that may maintain the brand new chips collectively, in addition to the agency’s course of for designing new chips in a method that may “present sustained innovation going ahead.” Papermaster described the foremost options of the Zen and Vega architectures for CPUs and GPUs, most of which had been described beforehand, and mentioned the agency has to design “not just for efficiency, but additionally for effectivity.”

AMD Infinity Fabric

Tying the chips collectively is the agency’s new Infinity Material, which connects CPUs, GPUs, reminiscence controllers, and different options inside a chip and between chip sockets. Papermaster known as Infinity Material a “hidden gem,” and defined the way it features a management cloth that manages sensors on the chip; can regulate efficiency and safety; and may also work as a knowledge cloth, transferring knowledge between the assorted elements of the system.

He mentioned this permits for “close to excellent scalability” via 64 CPU cores. AMD can also be supporting some new business customary interconnects between methods, often called Gen-Z & CCIX, because it pushes for open requirements (because it would not have the heft of Intel available in the market).

Papermaster mentioned that one large problem for the agency over the subsequent few years will probably be “defying the slowing of Moore’s Legislation.” He mentioned that via integration, software program, and system design it will be capable of keep on the tempo of generational efficiency enchancment, even with out frequency enhancements.

AMD x86 Roadmap

AMD graphics roadmap

To that finish, he confirmed roadmaps for each the graphics and CPU traces via 2020, saying that the staff was not solely rolling out the present era of merchandise, however engaged on the subsequent two. The plans present transferring to 7nm and 7nm+ manufacturing modes, with persevering with enhancements in each uncooked efficiency and efficiency per watt. Whereas these weren’t detailed, they had been nice to see.

A 16-core, 32-Thread CPU and a GPU Geared toward Machine Studying

AMD Ryzen Rollout

Jim Anderson, Basic Supervisor of the Computing and Graphics group, mentioned that along with the Ryzen 7 and Ryzen 5 merchandise already introduced, a lower-end Ryzen three will ship within the third quarter. Extra importantly, all 5 of the highest PC OEMs (Acer, Asus, Dell, HP, and Lenovo) can have Ryzen desktops accessible for shoppers available in the market by the tip of the quarter. Industrial desktops ought to comply with within the second half of this yr, he mentioned.

For these within the “absolute highest efficiency,” Anderson introduced a brand new model known as Ryzen Threadripper with 16 cores and 32 threads coming “this summer time.”

Anderson mentioned cell model of the Ryzen processor, with on-die Vega graphics, will probably be accessible for shopper methods within the second half of 2017. A business model ought to comply with within the first half of 2018. He mentioned the cell chip will provide 50 p.c extra CPU efficiency and 40 p.c extra GPU efficiency whereas utilizing 50 p.c much less energy in comparison with the corporate’s present seventh-generation APU.

Raja Koduri, Chief Architect for the AMD Radeon Technologies Group

In the meantime, within the graphics world, Raja Koduri, Chief Architect for the Radeon Applied sciences Group, mentioned the corporate’s plans for a brand new collection of graphics boards based mostly on the brand new Vega structure. Koduri famous that the corporate’s present Polaris structure GPUs principally handle the mainstream and mid-market segments of the graphics market (with graphics boards below $300), and acknowledged that the corporate did not play on the prime finish.

This may change with the brand new Vega structure. Among the many options Koduri described had been a brand new high-bandwidth cache controller (which might double or quadruple the accessible reminiscence), a brand new programmable geometry pipeline, Fast Packed Math (for 16-bit floating level), and a complicated pixel engine. He confirmed demos that includes a lot smoother movement in high-end gaming and mentioned Vega will assist 4K 60 Hz gaming.

For the skilled market, Koduri talked about getting extra certifications and supporting SSG, which can enable for a 16GB high-bandwidth cache and as much as 2TB of on-board SSG NVME flash reminiscence. He confirmed demonstrations of this working in real-time ray-tracing and on producing 8K video clips in Adobe Premiere.

AMD ROCm Software Stack

Koduri then turned his consideration to machine studying, the place competitor Nvidia has made enormous inroads in deep studying with its GPU-based merchandise and its CUDA structure. He acknowledged that “AMD is just not even within the dialog immediately,” however emphasised the corporate’s heterogenous computing strategy and what it calls the Radeon Open Compute Platform (ROCm), which helps operating machine studying purposes on the entire main frameworks, together with TensorFlow and Caffe.

Koduri demonstrated the brand new product, which will probably be known as Radeon Vega Frontier Version, and confirmed that it is vitally aggressive on Baidu’s DeepBench machine studying coaching benchmark. He mentioned this can provide 13 teraflops of efficiency at 32-bit, 25 teraflops at 16-bit, in addition to as much as 16GB of high-bandwidth reminiscence (HBM2), which is 4 occasions that of AMD’s present Fury X board. That is due out in late June. One would assume different Vega-based boards will comply with shortly.

Koduri mentioned that he believes Threadripper and Naples will probably be disruptive, partly as a result of the CPU bottlenecks will go away, leaving extra room for GPU efficiency.

AMD Guarantees ‘A New Day for the Datacenter’

Forrest Norrod, SVP and Basic Supervisor for the Enterprise, Embedded and Semi-Customized Enterprise Group, gave particulars on the Epyc server ship. He mentioned “datacenter management” is the corporate’s No. 1 precedence, regardless of having what he described as “a rounding to zero share market share.”

Norrod mentioned the corporate’s earlier achievements in server expertise—which embody having created the primary 64-bit x86 cores, high-speed coherent interconnects, and built-in reminiscence controllers—are what make it “believable… predictable… inevitable” for it to once more compete on this market.

Forrest Norrod, SVP and General Manager for the Enterprise, Embedded and Semi-Custom Business Group

Norrod mentioned that Epyc will embody 32 Zen cores, Eight reminiscence channels, 128 lanes of excessive bandwidth I/O, and a devoted safety engine. However whereas that appears like an enormous chip, Norrod defined that the Infinity Material Papermaster described earlier permits the chip to truly be constructed from 4 Eight-core die, which makes it a lot simpler and cheaper to supply.

Norrod mentioned that in a two-socket configuration, the chip may provide 64 cores, 4TB reminiscence, and 128 PCI Specific lanes, thus giving it 45 p.c extra cores, 122 p.c extra reminiscence bandwidth, and 60 p.c extra I/O than the Xeon E5-2699A v4 (Broadwell). And he introduced a few demos that confirmed it outperforming the Xeon in duties corresponding to compiling Linux.

I used to be extra impressed with a demo of how a single-socket model of the chip may outperform a center of the market dual-socket Intel configuration, which he mentioned accounts for many of the market. (As at all times, I take vendor benchmarks with a grain of salt, and counsel you do as nicely.)

Epyc will provide the “greatest worth for finish customers,” he mentioned. AMD is in search of management in particular segments of the market; Norrod famous it is more likely to get traction at first from the larger datacenter clients who write their very own software program. One large distinction between AMD and Intel’s strategy, he mentioned, is that each Epyc will probably be “unrestrained, with the entire I/zero, reminiscence channel, high-seed reminiscence, safety stack, and built-in chipset options supported on all fashions. (Intel provides sure options solely on higher-end fashions).

Epyc Machine Learning

Norrod mentioned Epyc provides an easier structure in comparison with Intel, and made a giant deal about combining Epyc and the Radeon Intuition platform for machine studying. Norrod mentioned Epyc is scheduled to be launched in late June, with greater than 30 server fashions anticipated to be shipped this yr.

AMD server roadmap

Norrod additionally careworn that that is the primary in a collection of chips, and introduced a roadmap with variations known as “Rome” and “Milan” (to comply with “Naples”) between now and 2020, utilizing 7nm and 7nm+ processes. He emphasised that it’s not all about core efficiency, however reasonably steady innovation.

Following a monetary presentation, CEO Lisa Su returned to shut the occasion, and advised the monetary analysts that whereas the numbers are necessary, “this firm is all concerning the merchandise.” It is actually good for the business to have extra competitors in CPUs, graphics, and particularly within the knowledge middle market. In spite of everything, the intervals once we’ve seen essentially the most competitors have additionally been the intervals once we’ve seen essentially the most innovation.
