UPDATE 9/15 07:30 ET: Due to a misunderstanding of the context, we incorrectly said that the 52-core Xeon Platinum 8472C featured 64GB of on-package HBM2E memory. In a Twitter post @Yuuki_AnS said that none of the Sapphire Rapids processors in his leaked test results carried HBM2e memory. We have removed mentions of the 64GB of on-package HBM2E DRAM and corrected our comments.
A well-known blogger has shared perhaps the first performance numbers of Intel’s upcoming Xeon Platinum Sapphire Rapids (opens in new tab) processors with 52 and 60 cores in the V-Ray benchmark. Apparently, neither a 60-core Intel CPU nor the 52-core Xeon CPU working at high frequencies can beat AMD’s high-end EPYCs available today.
Some of Intel's customers already get PRQ versions of select 4th Generation Xeon Scalable Sapphire Rapids processors. Still, the launch of high-volume models has suffered a delay to late 2022, with a full-scale ramp now scheduled for 2023 as the company had to correct certain bugs in silicon and then re-qualify those CPUs with partners. Intel keeps specifications of its upcoming products under wraps. Since there are many Sapphire Rapids processors in the wild already, not only do we know some of their alleged specifications, but their performance numbers have surfaced ahead of launch.
YuuKi_AnS, a prominent hardware leaker with a good track record and access to unreleased hardware, has laid his hands on Intel's 60-core Xeon Platinum 8490H CPU and a 52-core Xeon Platinum 8472C processor. The hardware blogger not only disclosed the specifications of the said products but also published their benchmark result. All the information is proven by screenshots (see the gallery below), so everything looks somewhat credible, while there may be some bumps. Meanwhile, since we are dealing with pre-production hardware, take the results with a grain of salt.
|Header Cell - Column 0||Cores/Threads||Cache L2+L3||Frequency||TDP - PBP - MTP|
|Xeon Platinum 8472C*||52/112||112MB + 97.5MB||2.50 GHz – 3.80 GHz||350W – 420W – 764W|
|Xeon Platinum 8490H*||60/120||120MB + 112.5MB||1.90 GHz – 3.50 GHz||350W – 420W – 764W|
*Specifications are unconfirmed.
Last spring, Intel only planned to release Sapphire Rapids CPUs with up to 56 cores, but now the company is testing 60-core Xeon Platinum 8490H processors running at 1.90 GHz – 3.50 GHz. Furthermore, the company looks to be testing 52-core Xeon Platinum 8472C CPUs running at considerably higher 2.50 GHz – 3.80 GHz.
|Header Cell - Column 0||CPU-Z Single-Thread||CPU-Z Multi-Thread|
|Xeon Platinum 8472C||542.5||31,954.3|
|Xeon Platinum 8490H||508||32,747.6|
Due to higher frequency, Intel's Xeon Platinum 8472C offers slightly higher single-thread performance than the company's Xeon Platinum 8490H CPU in the CPU-Z 2.02.0 benchmark. Yet the 60-core model scores marginally higher in multi-threaded workloads.
|Header Cell - Column 0||Threads and Frequency||V-Ray Score (K samples)|
|2x Xeon Platinum 8472C||224 @ 2.50 – 3.80 GHz||95,014|
|2x Xeon Platinum 8490H||240 @ 1.90 – 3.50 GHz||71,830|
|2x AMD EPYC 7773X||256 @ 2.20 – 3.50 GHz||102,843|
|2x AMD EPYC 7763||256 @ 2.45 – 3.50 GHz||109,248|
Rendering workloads of Chaos's V-Ray 4.10.03 benchmark can take advantage of both many cores and higher per-core performance (i.e., higher clocks). Apparently, clocks play quite a role here as we can notice based on results of AMD and Intel CPUs. Intel's 52-core Xeon Platinum 8472C is about 32% faster when compared to its 60-core Xeon Platinum 8490H sibling, possibly because the pre-production 60-core CPU cannot hit high clocks for prolonged periods. There could be some issues with BIOS/microcode too as we are not dealing with production hardware.
Interestingly, AMD's EPYC 7773X (Milan-X with 3D V-Cache) does not have any edge over the EPYC 7763 processor, which runs only a tad faster. Nonetheless, both already available CPUs are currently untouchable by Intel's offerings that have yet to come to market.
One thing that YuuKi_AnS pointed out is that new BIOS versions tend to add performance to Intel's Sapphire Rapids CPUs. So, assuming that there will be further microcode optimizations of these processors, production servers and workstations based on these CPUs will offer higher performance than current samples. But until those machines arrive, all we have left is to analyze results obtained on pre-production CPUs.
I find comparisons between ADL and Zen 3 much more telling in power-constrained scenarios such as mobile or data center usage; here performance gaps are much more muted, if non-existent.
They will be released in H2 2023. They will use socket 99999 and 4000w TDP.
Sorry, delayed to end 2023.
Sorry, delayed to q2 2024
Sorry, delayed to end 2024
Sorry, delayed to
Sorry, sorry, sorry.
Why do I the feeling saphhire rapids was never intended for 2022 launch and was merely announced to decrease AMD sales.
and now zen 4 pushes the power up. it's the tactic this time around
