    It's unbelievable that over the whole course of PS3's lifespan we've gone from "we will never be able to emulate this at full speed, the hardware is too slow and the Cell architecture too alien" to "why is PS3 emulation so fast, optimizations explained". I've been loosely tracking various emulators' progress and it's hats off with regards to the ingenuity behind all of the mechanisms that make it possible to emulate things fast enough.

    What’s particularly interesting here is that Sony and IBM spent a billion dollars to make the Cell. It was designed to be completely different from previous console CPUs. Even more so than the PS2’s “emotion engine” combo. So the fact that it’s so well emulated and also performant is remarkable!

    Happy that RPCS3 has added native apple silicon support

    I never thought PS3 emulation would be significantly ahead of Xbox 360 emulation.
