Intel Alder Lake enabling AVX-512 will improve RPCS3 performance

In August of this year, PlayStation 3 emulator RPCS3 has announced support for FidelityFX Super Resolution (FSR) technology. However, because the PlayStation 3 emulator is very restricted by the performance of the CPU, the advantage of FidelityFX Super Resolution may not be as obvious as that of general PC platform games. At the same time, games that lack anti-aliasing may have worse picture quality after FidelityFX Super Resolution is turned on, and the loss will become pixelated. In any case, the enterprising spirit of the RPCS3 development team in using new technologies is still worth encouraging.

Recently, RPCS3 officially demonstrated the use of Intel’s 12th-generation Core series processors, after enabling the AVX-512 instruction set, the performance improvement when running the PlayStation 3 emulator. Intel’s hybrid architecture Alder Lake processor has a performance core based on the Golden Cove architecture (Performance Core) and an energy efficiency core based on the Gracemont architecture (Efficient Core). After closing E-Core, only P-Core can enable the AVX-512 instruction set.

At the same 5.2 GHz frequency, when running “God of War”, the Core i9-12900K is about 15% faster than the previous generation Core i9-11900K, with an increase of more than 10FPS, both of which have the AVX-512 instruction set enabled and disabled hyperthreading. Intel’s 11th-generation Core series processors run PlayStation 3 emulators more efficiently than Zen 3 architecture products, and now the gap between the 12th-generation Core series has become greater. It is a pity that there is currently a lack of operating conditions when P-Core and E-Core are turned on at the same time, and the AVX-512 instruction set is disabled.

RPCS3 is one of the few places in the game field that can demonstrate the performance of the AVX-512 instruction set, thanks to the efforts of its development team. At present, RPCS3 has basically achieved the goal of compatibility with all PlayStation 3 games, and more than 2000 published games have been marked as “playable”. However, there are still a few games that have bugs when they are loaded and need to be fixed. However, compared with the PlayStation 3 games that only supported 62% of the PlayStation 3 games a few months ago, it has made great progress.
