- Macha 7y agoRight, but 1-2x perf is not nearly enough to naively emulate a system.
- ridiculous_fish 7y agoRosetta was not a naive emulator. It was a dynamic, optimizing re-compiler. There's two reasons to think that an ARM transition would be easier: 1. The endianness is the same. The PPC/Intel transition required processes to share memory while disagreeing on byte order. 2. Apple controls their ARM CPU designs. They can add whatever they like.
- andrekandre 7y agoright, and 3. rosetta only emulated the actual app binary; eventually it called in to native libs, so performance for the most part held up really well iirc (for apps, not sure about games)
