This is extremely different, apple was targeting end consumers that just want their app to run. The performance between apple rosetta and native cpu were still multiple times different.

People writing CUDA apps don't just want stuff to run, performance is an extremely important factor else they would target CPUs which are easier to program for.

From their readme: > On Server GPUs, ZLUDA can compile CUDA GPU code to run in one of two modes: > Fast mode, which is faster, but can make exotic (but correct) GPU code hang. > Slow mode, which should make GPU code more stable, but can prevent some applications from running on ZLUDA.

Not at all, the performance hit was in the low 10s %, before natively supporting Apple Silicon most of the apps I use for music/video/photography didn't seem to have a performance impact at all, even more when the M1 machines were so much faster than the Intels.

Rosetta 2 runs apps at 80-90% their native speed.

Indeed I got that wrong. Sadly minimal SIMD and hardware acceleration support.

not really the same in that Apple was absolutely required to do this in order for people to transition smoothly and it wasn't competing against another company / platform, it just needed apps from its previous platform to work while people recompile apps for the current one which they will
