Sapphire Rapids HBM2E CPUs Fall Behind EPYC 3D V-Cache CPUs In Leaked Benchmarks

(*4*)

A well known blogger has shared possibly the primary efficiency collection of Intel’s upcoming Xeon Platinum (*6*)Sapphire Rapids processors with 60 cores and HBM2E cache.

A few of Intel’s shoppers already get (*1*)PRQ variations (opens in new tab) of choose 4th Technology Xeon Scalable Sapphire Rapids processors. Nonetheless, the release of high-volume fashions has suffered a lengthen to overdue 2022, with a full-scale ramp now scheduled for 2023 as the corporate needed to (*5*)right kind positive insects in silicon after which re-qualify the ones CPUs with companions. Intel helps to keep specs of its upcoming merchandise underneath wraps. Since there are lots of Sapphire Rapids processors within the wild already, no longer most effective do we all know a few of their alleged specs, however their efficiency numbers have surfaced forward of release.

(*3*)YuuKi_AnS (opens in new tab), a outstanding {hardware} leaker with a excellent observe report and get right of entry to to unreleased {hardware}, has laid his palms on Intel’s 60-core Xeon Platinum 8490H CPU and a 52-core Xeon Platinum 8472C processor, probably provided with 64GB of HBM2E cache. The {hardware} blogger no longer most effective disclosed the specs of the mentioned merchandise but additionally printed their benchmark end result. The entire data is confirmed by way of screenshots (see the gallery underneath), so the entirety seems to be relatively credible, whilst there is also some bumps. In the meantime, since we’re coping with pre-production {hardware}, take the effects with a grain of salt.

Closing spring, Intel most effective deliberate to liberate Sapphire Rapids CPUs with as much as 56 cores, however now the corporate is checking out 60-core Xeon Platinum 8490H processors operating at 1.90 GHz – 3.50 GHz. Moreover, the corporate seems to be to be checking out 52-core Xeon Platinum 8472C CPUs with on-package 64GB of HBM2E reminiscence and operating at significantly upper 2.50 GHz – 3.80 GHz.

Xeon Platinum 8490H50832,747.6

Because of upper frequency, Intel’s Xeon Platinum 8472C gives somewhat upper single-thread efficiency than the corporate’s Xeon Platinum 8490H CPU within the CPU-Z 2.02.0 benchmark. But the 60-core fashion rankings marginally upper in multi-threaded workloads.

Whilst core depend and frequencies impact efficiency in nearly all workloads, including HBM2E reminiscence (with a 1.22 TBps top bandwidth) advantages choose reminiscence bandwidth-bound workloads, equivalent to computational fluid dynamics and rendering.

Threads and Frequency V-Ray Rating (Okay samples)
2x Xeon Platinum 8472C224 @ 2.50 – 3.80 GHz95,014
2x Xeon Platinum 8490H240 @ 1.90 – 3.50 GHz71,830
2x AMD EPYC 7773X256 @ 2.20 – 3.50 GHz102,843
2x AMD EPYC 7763256 @ 2.45 – 3.50 GHz109,248

It’s exactly what we see in Chaos’s V-Ray 4.10.03 benchmark, which will profit from each many cores and better per-core efficiency. 64GB of HBM2E reminiscence performs a extra important position right here, which is why the Xeon Platinum 8472C is ready 32% quicker when in comparison to its Xeon Platinum 8490H sibling.

Curiously, AMD’s EPYC 7773X (Milan-X with 3-D V-Cache) does no longer have any edge over the EPYC 7763 processor, which runs just a tad quicker. Nevertheless, each already to be had CPUs are lately untouchable by way of Intel’s choices that experience but to come back to marketplace.

Something that YuuKi_AnS identified is that new BIOS variations generally tend so as to add efficiency to Intel’s Sapphire Rapids CPUs. So, assuming that there can be additional microcode optimizations of those processors, manufacturing servers and workstations in keeping with those CPUs will be offering upper efficiency than present samples. However till the ones machines arrive, all we’ve left is to investigate effects received on pre-production CPUs.
