BIOS Optimizations For AMD 5th Gen EPYC Yield Greater HPC Performance & Power Efficiency
When taking the geo mean for the four dozen HPC benchmarks run for this article, following AMD's public BIOS tuning guide recommendations for HPC computing workloads there was a 22% improvement to the performance overall. That's pretty darn good considering that my EPYC and Xeon reviews and other CPU review/benchmark comparisons are done with stock/BIOS default settings except for where otherwise noted. Some pretty nice performance gains demonstrated across different software packages like (Open)Radioss, OpenFOAM, HPCG, Graph500, SPECFEM3D, XNNPACK, Incompact3D, and others for bettering the 5th Gen AMD EPYC potential for high performance computing.
The HPC tuning recommendations were great for the raw performance benefit but the impact on power efficiency was equally captivating too. The HPC tuning recommendations typically led to lower AMD EPYC 9575F power consumption and in turn lower overall AMD EPYC server power consumption too on this Supermicro 4U 1P server build. Even for the subset of HPC workloads not benefiting directly with greater performance, they tended to enjoy greater power efficiency in following AMD's public tuning guide. This tuning guide has worked out pretty well and conveniently laid out for efficient tuning of AMD EPYC 9005 server power/performance across different clases of workloads. Now onto more EPYC benchmarking over the holidays like some of the recent kernel patches for further optimizing performance. The benchmarking for better or worse never ends.
