While the AMD EPYC 9754 "Bergamo" processor is impressive for having 128 physical Zen 4C cores, it also has Simultaneous Multi-Threading (SMT) to provide for 256 threads per socket. Meanwhile with Ampere Altra Max and AmpereOne there is no SMT and it's likely Intel's upcoming Sierra Forest will also lack SMT (Hyper Threading) given it's an E-core-only design. But that led to my curiosity over the SMT impact for Bergamo on power and performance when leveraging SMT for the 128-core flagship EPYC 9754. Today's Bergamo benchmarking is looking at SMT on and off for both 1P and 2P server configurations.

While Intel is well known -- and well regarded -- as being one of the top contributors to the Linux kernel as well as being a significant player in many other open-source projects with their countless open-source software contributions over the years, Arm is now trying to better promote their open-source support and open contributions...

In addition to the review embargo lift today for Genoa-X with our AMD EPYC 9684X benchmarks, the lift is also today on the new AMD EPYC "Bergamo" processors for offering up to 128 cores / 256 threads per socket using the new Zen 4C core. In this article is an initial look at the performance provided by the AMD EPYC 9754 128-core processors.

Last year AMD launched Milan-X as their first server processors with 3D V-Cache. The performance uplift from the 768MB of L3 cache per socket was phenomenal, but now here we are today with the next-generation successor: Genoa-X. The flagship EPYC 9684X is the new leader for HPC and AI performance as in addition to a 1.1GB L3 cache it leverages AMD's modern Zen 4 micro-architecture with AVX-512, 12 channel DDR5 memory, and other improvements found with existing EPYC 9004 series processors to easily triumph as the new best CPU for high performance computing from CFD and FEA to dozens of other scientific workloads. Here are the first benchmarks of the AMD EPYC 9684X processors.
