The Performance Impact Of Genoa-X's 3D V-Cache With The AMD EPYC 9684X

Phoronix - Mon, 07/24/2023 - 23:18
Last week in the AMD EPYC 9684X review were many benchmarks looking at how this flagship Genoa-X processor compares to various AMD EPYC and Intel Xeon processors. The EPYC 9684X delivers terrific generational uplift compared to Milan-X, offers significant advantages over the EPYC 9004 Genoa processors thanks to the 1.1GB of L3 cache per CPU that proves very beneficial in HPC and AI workloads, and the 96-core / AVX-512 / 3D V-Cache combination far surpassed the Intel performance in the vast majority of benchmarks. As some follow-up benchmarks, today is looking precisely at the performance difference caused by the 3D V-Cache presence by looking at the EPYC 9684X performance when the 3D V-Cache feature was enabled and then the tests repeated when disabled.
