Sony PS3 Emulator

RPCS3 is a popular PlayStation 3 emulator for PCs, which lets you play many Sony PS3 titles on your favorite platform. The emulator has serious hardware requirements, and some of its emulation threads constantly need to communicate with each other, which makes it a tough workload for many CPU architectures. RPCS3 also benefits from faster cache and memory speeds, when available. AVX-512 is enabled where supported, including Zen 4 and Zen 5.

Nintendo Switch Emulator

Ryujinx is a highly compatible, feature-rich emulator for the Nintendo Switch console. It relies heavily on your CPU, and also comes with some tricks how to use the memory management unit (MMU) of your processor to handle the emulated environment. While it is multithreaded, higher single-core performance is more important than being able to scale to many cores.
