AMD EPYC 7773X "Milan-X" Performance Continues To Impress With Tremendous Opportunity For Large-Cache Server CPUs

Lastly, given the large number of benchmarks carried out, here is a look at the geometric means grouped by different workload types and then the overall geo mean.

The EPYC 7773X with AMD 3D V-Cache performed very well under BLAS-based workloads like WRF, NWChem, and GPAW.

Milan-X only had little advantage in the code compilation workloads if you are considering building a dedicated build box / CI setup, but at the same TDP and similar pricing to the EPYC 7763 makes it rather well-rounded.

Milan-X continues performing well in creator workloads like various Intel oneAPI software packages, ASTC texture compression, LuxCore renderer, Blender, and other similar workloads.

For conventional HPC workloads from the NPB benchmarks to NAMD, GROMACS, NWChem, LAMMPS, MiniFE, Pennant, Incompact3D Xcompact3D, OpenFOAM, GPAW, RELION, and others, the AMD EPYC 7773X processors really shined.

Or more broadly at all of the scientific computing benchmarks carried out, the AMD EPYC 7773X was dominating.

When taking the geometric mean of all 137 raw performance benchmarks conducted for this article, the EPYC 7773X 2P averaged out to being 15% faster than the EPYC 7763 2P or 20.7% faster than the Xeon Platinum 8380 2P. In 1P configuration, the EPYC 7773X was 11% faster than the 7763 and 37% faster than the Xeon Platinum 8380. The EPYC 7773X with AMD 3D V-Cache helped a variety of workloads and even in areas where there was only small benefits, it still makes for a competitive product with a similar power draw to the EPYC 7763 and in current market conditions is priced competitively with the EPYC 7763 and the Intel Xeon Scalable competition.

Overall I continue to be extremely impressed by the AMD EPYC 7773X performance across a wide variety of workloads. These latest benchmarks using the newest Linux kernel, the Ubuntu 22.04 stable release, newer Daytona firmware and CPU microcodes across, and new/updated benchmarks continue to show the significant market potential for AMD Milan-X and future 3D V-Cache products. The performance uplift can be substantial, the power draw is similar to the non-X EPYC 7763, and current pricing remains very competitive. Later this year AMD EPYC Genoa is launching but presumably Genoa-X isn't launching until later or even next year, still giving interesting market life to Milan-X. It will be interesting to re-visit this testing again in the months ahead as more software becomes better optimized for large L3 caches, especially with the more affordable AMD Ryzen 7 5800X3D being within reach for more open-source software developers. On the opposite side of the table, it will be interesting as well when time comes for seeing how Xeon Sapphire Rapids with HBM2e memory performs.
