New benchmarks of the Intel Xeon Platinum 8468 48-Core Sapphire Rapids CPU have leaked out which present aggressive efficiency versus AMD’s Milan.
Intel Xeon Platinum 8468 48-Core “Sapphire Rapids” CPU Trades Blows With AMD’s EPYC 7763 64-Core “Milan” Chips
The benchmark that has been found by HXL (@9550pro) reveals us an engineering pattern of the Intel Xeon Platinum 8468, one of many many Sapphire Rapids-SP CPUs. Based on the specs sheet that leaked earlier, the Xeon Platinum 8468 goes to function 48 cores and 96 threads whereas utilizing the 10nm ESF course of node and the Golden Cove core structure. The CPU is predicted to function 105 MB of L3 cache & a 350W TDP. The CPU is listed with 2.1 GHz clocks inside Cinebench R23 and 800 MHz inside CPU-z which means that the clock speeds aren’t near the retail numbers.
The CPU examined is the sixth Stepping and we all know from earlier studies that the Sapphire Rapids-SP chips have gone via various steppings to fix various bugs that the chips have encountered to this point. It is reported that the CPU was examined inside two benchmarks, one being Cinebench R23 & the opposite being V-Ray. The CPU was examined in a dual-socket configuration with 96 cores & 192 threads in complete.
Starting with Cinebench R23, the chip scored 90411 factors in multi-core and 1351 factors in single-core. The CPU is unquestionably sooner than retail EPYC Milan chips in single-core and comparable within the multi-core checks for the reason that prime EPYC 7763 scores round 90000-95000 factors in the identical take a look at. This implies that the EPYC 7763 is at finest 8.5% sooner in multi-threaded efficiency, a distinction that may simply be overcome by last retail clock speeds. The EPYC chip additionally contains 33% extra cores.
Compared to an early ES EPYC Genoa chip, the Intel Xeon Platinum 8468 CPU with 48-cores and 96 threads or 96 cores and 192 threads in complete is round 18% slower however as soon as once more, the Genoa chip affords 33% extra threads. The full potential of EPYC Genoa 96-core chips is restricted to 256 threads since that is the utmost thread restrict.
We even have V-Ray the place the Intel Xeon Platinum 8468 48-Core CPUs are listed in a 4-socket config however it was really working a 2-socket config. The CPU clock velocity is rated a bit increased at 3.0 GHz & the rating is rated at 85,766 samples. Following is how the efficiency compares to different server chips:
Intel has moved the Sapphire Rapids-SP Xeon CPU launch to early 2023 so it appears like they are going to be competing with EPYC Genoa-X & Bergamo CPUs by the point they’re broadly obtainable to x86 server prospects. This type of efficiency would have been aggressive just a few years again towards Milan however with Zen 4 on the horizon, issues look grim for Intel regardless of the most important uplift over Ice Lake-SP which now appears too little.
