M1 has (fast) unified memory between GPU and CPU, so something being memory bound ought not to have much bearing on whether it belongs on CPU or GPU… at least in theory. I’m a total noob here though so I may be wrong.
- GaggiX 3y agoWe were discussing mostly about NPU, I don't know if it makes a difference.
- lib-dev 3y agoFrom https://en.wikipedia.org/wiki/Apple_M1#Memory https://en.wikipedia.org/wiki/Apple_M1#Memory > The M1 uses a 128-bit LPDDR4X SDRAM in a unified memory configuration shared by all the components of the processor. I assume that includes the NPU, media engine, etc.
