The M-series have a built-in GPU and unified RAM accessible to both. Running a model on an M-series chip without using the GPU is, imho, pointless. (That said, it's still a long shot from an H100 with a ton of VRAM, or from a Google TPU.) If a model can be "run on a CPU", it should acceptably run on a general-purpose 8-core CPU, like an i7, or i9, or a Ryzen 7, or even an ARM design like a Snapdragon.
