Revisiting AMD EPYC 7773X "Milan-X" Performance With Linux 6.0 + Ubuntu 22.10

Like with the Milan-X benchmarks going back to launch, the EPYC 7773X can provide very meaningful performance improvements over the EPYC 7763 Milan (non-X) flagship especially for HPC workloads.

The often big performance improvements with usually only slightly higher power consumption. Both the 7763 and 7773X are rated for a 280 Watt TDP and across the many benchmarks carried out at most the 7773X tended to be 10~20 Watts higher than the 7763 depending upon the particular workload under test.

Across a wide range of workloads from conventional "HPC" benchmarks to AI workloads with Intel OpenVINO, AMD Milan-X was showing the benefits of the large cache. With Intel Xeon Scalable Sapphire Rapids also having some SKUs with HBM memory, it will be very interesting to see how Intel competes with those next-generation products.
