Intel’s Third-generation Xeon Scalable CPUs provide 16-bit FPU processing

Intel at present introduced its third-generation Xeon Scalable (that means Gold and Platinum) processors, together with new generations of its Optane persistent reminiscence (learn: extraordinarily low-latency, high-endurance SSD) and Stratix AI FPGA merchandise.

The truth that AMD is at present beating Intel on nearly each conceivable efficiency metric besides hardware-accelerated AI is not information at this level. It is clearly not information to Intel, both, for the reason that firm made no claims by any means about Xeon Scalable’s efficiency versus competing Epyc Rome processors. Extra apparently, Intel hardly talked about general-purpose computing workloads in any respect.

Discovering a proof of the one non-AI generation-on-generation enchancment proven wanted leaping by way of a number of footnotes. With ample dedication, we ultimately found that the “1.9X common efficiency achieve” talked about on the overview slide refers to “estimated or simulated” SPECrate 2017 benchmarks evaluating a four-socket Platinum 8380H system to a five-year-old, four-socket E7-8890 v3.

To be honest, Intel does appear to have launched some unusually spectacular improvements within the AI house. “Deep Studying Enhance,” which formally was simply branding for the AVX-512 instruction set, now encompasses a wholly new 16-bit floating level knowledge sort as properly.

With earlier generations of Xeon Scalable, Intel pioneered and pushed closely for utilizing 8-bit integer—INT8—inference processing with its OpenVINO library. For inference workloads, Intel argued that the decrease accuracy of INT8 was acceptable generally, whereas providing excessive acceleration of the inference pipeline. For coaching, nonetheless, most functions nonetheless wanted the larger accuracy of FP32 32-bit floating level processing.

The brand new technology provides 16-bit floating level processor assist, which Intel is asking bfloat16. Reducing FP32 fashions’ bit-width in half accelerates processing itself, however extra importantly, halves the RAM wanted to maintain fashions in reminiscence. Benefiting from the brand new knowledge sort can also be easier for programmers and codebases utilizing FP32 fashions than conversion to integer can be.

Intel additionally thoughtfully supplied a recreation revolving across the BF16 knowledge sort’s effectivity. We can’t suggest it both as a recreation or as an academic software.

Optane storage acceleration

Intel additionally introduced a brand new, 25 percent-faster technology of its Optane “persistent reminiscence” SSDs, which can be utilized to drastically speed up AI and different storage pipelines. Optane SSDs function on 3D Xpoint expertise somewhat than the NAND flash typical SSDs do. 3D Xpoint has tremendously increased write endurance and decrease latency than NAND does. The decrease latency and larger write endurance makes it notably enticing as a quick caching expertise, which may even speed up all solid-state arrays.

The large takeaway right here is that Optane’s extraordinarily low latency permits acceleration of AI pipelines—which regularly bottleneck on storage—by providing very fast entry to fashions too giant to maintain solely in RAM. For pipelines which contain fast, heavy writes, an Optane cache layer may considerably enhance the life expectancy of the NAND main storage beneath it, by decreasing the full variety of writes which should truly be dedicated to it.

For instance, a 256GB Optane has a 360PB write-endurance spec, whereas a Samsung 850 Professional 256GB SSD is just specced for 150TB endurance—larger than a 1,000:1 benefit to Optane.

In the meantime, this wonderful Tom’s {Hardware} evaluation from 2019 demonstrates simply how far within the mud Optane leaves conventional knowledge center-grade SSDs when it comes to latency.

Stratix 10 NX FPGAs

Lastly, Intel introduced a brand new model of its Stratix FPGA. Subject Gate Programmable Arrays can be utilized as {hardware} acceleration for some workloads, permitting extra of the general-purpose CPU cores to deal with duties that the FPGAs cannot.
