Many console gamers have heard of RPCS3, a multiplatform open source Sony PlayStation 3 emulator. Whatcookie, the name behind RPCS3, has released a patch that uses the AVX-512 instruction set and brings a 30% performance increase. Until now, AVX-512 support hasn’t meant much for games, but when it comes to an emulator, the scenario can change.
It should be noted that the 30% performance increase was achieved in the tests made with the Core i9-12900K. The Core i9-12900K is already quite performant, but these optimizations are much more important for low-power systems. In addition, AMD’s upcoming Ryzen 7000 processors will also have AVX-512 acceleration. In the screenshot below, you can see the tests performed with SSE2, SSE4.1, AVX2/FMA and AVX-512 instruction sets from left to right.
Intel announced earlier this year that it will remove AVX-512 instruction set support for its 12th generation processors. It’s actually listed in the Alder Lake series developer’s guide along with the AVX-512 instructions. According to this guide, initially AVX-512 support was only available for large (performance) cores in Alder Lake desktop CPUs, but Intel later changed the guide and listed AVX512 as disabled. Alder Lake processors, released from a certain date, come without AVX-512 support.
