Are you saying that the torch performance with MPS support enabled didn't meet your performance expectations? Or are you using an intel macbook and/or one with a tiny amount of ram/vram?
The M1 was released in 2020, chances are by now a macbook has ARM and neural cores which are ok to do local inference
They’re OK, but certainly a lot slower than with an Nvidia GPU.
Modern MacBooks are great at this stuff since they have unified memory and the GPU can use all of it
