PlayStation 3 Emulator RPCS3 updated with AMD Zen 5 Ryzen 9000 CPU support
RPCS3, the PlayStation 3 emulator, now supports AMD Zen 5 CPUs
RPCS3, the popular PlayStation 3 emulator, has been updated to support AMD’s upcoming Ryzen 9000 series Zen 5 processors. Thanks to an LLVM error uncovered by kd-11, AMD’s new CPUs were detected as “generic” processors, resulting in poor emulator performance and other issues. Now, RPCS3 v0.0.32-16742 or newer versions now allows Ryzen 9000 CPUs to work more optimally with RPCS3.
This fix is a temporary workaround that effectively allows RPCS3 to treat AMD Zen 5 CPUs as AMD Zen 4 processors. Future versions of RPCS3 with an updated LLVM will allow Zen 5 CPUs to be detected properly.
Before this update, early users of AMD’s Ryzen 9000 series CPUs experienced crashing and sub-optimal performance with AMD’s new CPUs. Thankfully, these issues were the result of a minor software issue that was quickly fixed by the RPCS3 team.
AMD’s Ryzen 9000 series CPUs are expected to perform well when emulating PlayStation 3 games. RPCS3, like some other emulators, benefits from AVX-512 support. One of the key improvements to Zen 5 is its boosted AVX-512 performance. When combined with other architectural improvements, AMD’s Zen 5 CPUs should be able to deliver boost PS3 emulation speeds compared to Zen 4.
An update to RPCS3 improving CPU features detection for unreleased/upcoming CPUs is now available, starting on RPCS3 v0.0.32-16742.
If you already have one of these upcoming CPUs for testing you must update RPCS3, otherwise you might experience very low performance and crashes.

Recently, the RPCS3 emulator celebrated its 13th anniversary. Now, the emulator has 70% of the PlayStation 3’s library classed as “playable”. Unquestionably, RPCS3 is now the best way to replay many PlayStation 3 classics. This is because the emulator can run many of these classic games at higher framerates and resolutions than original PlayStation 3 hardware can. Moreover, mods are available for some PS3 games to deliver further improvements.
