While some applications like 7zip, Blender, and Firefox showed relatively modest performance dips, with 7Zip being the most impacted among these, the story was different for industrial-grade software. Specifically, applications related to database management, code compilation, engineering, and image processing witnessed notably diminished performance on patched Epyc server processors.
AMD has approached the mitigation process through three distinct methods: kernel-based mitigation, new microcode implementations, and the application of Indirect Branch Prediction Barrier (IBPB) mitigation. Among these approaches, IBPB is considered the most secure solution, but it also tends to result in the most pronounced performance slowdowns.
