RPCS3 is one of the most feature-packed PS3 Emulators out there that supports thousands of PS3 titles. With the latest iteration of the emulator, the developers have now added support for the AVX-512 instructions on AMD’s Ryzen 7000 “Zen 4” CPUs.
The latest AMD CPUs with AVX-512 instructions offer noteworthy performance improvements. AMD itself claims that Zen 4 CPUs will offer a 30% improvement in FP32 inferencing and 2.5x uplift in INT8 inferencing performance with Advanced Vertex Extensions-512 (VNNI) support.
Latest build now detects AVX-512 out of the box for Zen 4 CPUs

In a tweet shared hardly a few days ago, RPCS3 stated that the emulator does not yet enable AVX-512 code paths for the brand new Zen 4 CPUs out of the box. However, just after a few days the developers have added support for AMD Ryzen 70000 Zen 4 AVX-512 CPU Instructions.
In addition to AMD, Intel’s Alder Lake CPUs also added AVX-512 acceleration on day one, and mainstream PS3 emulators like RPCS3 showed a performance boost of up to 30% in comparison to standard AVX2 CPUs. Sadly, Intel has removed AVX-512 support entirely from its consumer lineup and it’s now exclusively available on the Xeon chips.
