With the AMD EPYC 9005 "Turin" testing over the past month since launch I have looked at how well the new EPYC Turin CPUs compete against Intel Xeon, how Turin Dense dominates in performance and power efficiency to AmpereOne at 192 cores, and the generational uplift from EPYC Genoa to Turin at the same core counts, among other Turin performance benchmark tests. Up for comparison today is a look at how the NVIDIA Grace CPU performance within the GH200 Superchip compares to the AMD EPYC Turin processors.

The NVIDIA Grace CPU performance wasn't previously compared to the AMD EPYC 9005 "Turin" processors due to not having the hardware on-hand for comparison and the last time I did GH200 benchmarking was in early 2024 even before Ubuntu 24.04 LTS was released... So out-of-date / non-comparable data. But GPTshop.ai recently provided me remote access again to one of their NVIDIA GH200 systems for benchmarking. I've been able to carry out some fresh NVIDIA GH200 Grace CPU benchmarks among other GH200 testing for future articles. In today's article is a look at the GH200's Arm-based Grace CPU performance compared to the Zen 5 Turin cores within the EPYC 9005 series.

With the EPYC Turin tests being just CPU-focused, the GH200 testing was as well in looking at the Grace CPU performance with its 72 cores based on Arm Neoverse-V2 and 480GB of memory. All testing was based on Ubuntu 24.04 LTS albeit with a patched kernel on the EPYC side for having Zen 5 CPU power consumption monitoring. There was slightly different single NVMe drive storage due to having only remote access to this GPTshop.ai GH200 system. The default GCC 13.2 compiler was used on both platforms, Ubuntu 24.04 LTS running with the "performance" CPU frequency scaling driver. The GH200 system was also running with the 64K page size kernel for best AArch64 performance potential.
