I am pretty sure that Adobe products make heavy use SIMD/SSE/AVX extensions to speed up any image processing that is not offloaded to the GPU - I wonder how well Rosetta 2 translates the vectorized instructions. If not well, then the M1 is really in for a treat.
That said, it doesn't seem hard to do and I wouldn't be surprised if most instructions have near 1:1 equivalents. The only question is if Rosetta 2 authors got around to translating those.
Yea, I’ve heard the M1 has features to make JS compilation super fast.
For photoshopped I have no idea of which of the micro benchmarks have the most predictive ability for Photoshop performance. If it’s mostly memcpy, Rosetta2 is nearly as fast at that as native. But if it’s a lot of math we could see some substantial speed ups from the native Photoshop.

Assuming 75% on average that would increase the M1 benchmarks about 33%, bringing them much closer to the Ryzen Systems tested.
