Intel Xeon W9-3495 Sapphire Rapids HEDT CPU Spotted - Rocks 56 Cores, 112 Threads & a 1.80 GHz ES Clock Speed

Intel Xeon Platinum 8468 48-core ‘Sapphire Rapids’ CPU benchmark leaks, comparable to AMD’s 64-core Milan chip

New benchmarks for the Intel Xeon Platinum 8468 48-Core Sapphire Rapids CPU have leaked, and it shows competitive performance compared to AMD’s Milan.

Intel Xeon Platinum 8468 48-core ‘Sapphire Rapids’ CPU trades against AMD’s EPYC 7763 64-core ‘Milan’ chip

discovered benchmarks HXL (@9550pro) We were shown an engineering sample of the Intel Xeon Platinum 8468, one of many Sapphire Rapids-SP CPUs. According to a previously leaked spec sheet, the Xeon Platinum 8468 will feature 48 cores and 96 threads, using both the 10nm ESF process node and the Golden Cove core architecture. The CPU is expected to have 105 MB of L3 cache and a 350W TDP. The CPU was clocked at 2.1 GHz in Cinebench R23 and 800 MHz in CPU-z, suggesting that the clock speed isn’t anywhere near the retail numbers.

The tested CPU is step 6, and we know from previous reports that the Sapphire Rapids-SP chip has gone through various steps to fix the various bugs the chip has encountered so far. It is reported that the CPU was tested in two benchmarks, one is Cinebench R23 and the other is V-Ray. The CPU was tested in a dual socket configuration with a total of 96 cores and 192 threads.

Starting with Cinebench R23, the chip has a multi-core score of 90,411 points and a single-core score of 1,351 points. The CPU is definitely faster than the retail EPYC Milan single-core chip and comparable in the multi-core test, as the top EPYC 7763 scores around 90000-95000 points in the same test. This means that the EPYC 7763 is up to 8.5% faster in terms of multi-threaded performance, and the final retail clock speed can easily overcome this difference. The EPYC chip also includes 33 percent more cores.

The 48-core 96-thread or 96-core 192-thread Intel Xeon Platinum 8468 CPU is about 18% slower than the earlier ES EPYC Genoa chip, but the Genoa chip again offers 33% more threads. The full potential of the EPYC Genoa 96-core chip is limited to 256 threads, as this is the maximum thread limit.

We also have V-Ray, where the Intel Xeon Platinum 8468 48-core CPU is listed in a 4-socket configuration, but it actually runs a 2-socket configuration. The CPU clock speed was rated slightly higher at 3.0 GHz, and the score was rated at 85,766 samples. Here’s how the performance compares to other server chips:

Intel has delayed the release of the Sapphire Rapids-SP Xeon CPUs until early 2023, so it appears they will compete with the EPYC Genoa-X and Bergamo CPUs when they are widely used by x86 server customers. A few years ago, that kind of performance would have been competitive against Milan, but with Zen 4, things look grim for Intel, even though a big boost from Ice Lake-SP now looks too little.
