Benchmarking The Performance Impact To AMD Inception Mitigations
AI performance with software like Neural Magic DeepSparse wasn't impaired by the new CPU security mitigations.
It largely comes down to what workloads you are actively engaged in for whether you may be impacted by any performance slowdowns as a result of the new AMD Inception mitigations. When it comes to EPYC server workloads, the areas where there was additional overhead from the default "safe RET" mitigation modes was involving I/O like the code compilation speed and database workloads. For HPC, AI, CPU-based rendering, and other areas the performance was rather unchanged. The IBPB mitigation approach also showed some performance penalties but again that is an optional alternative mode to using safe RET.
