Well unless they also support acceleration on AMD GPUs, this is not so interesting. Training on x86_64 CPU cores or integrated Intel GPUs is really slow compared to training on modern NVIDIA GPUs with Tensor Cores (or AMD GPUs with ROCm, if you can get the ROCm stack running without crashing with obscure bugs).

Also see the benchmarks in the marketing PR:

The M1 blows away Intel CPUs with integrated GPUs (and modern NVIDIA GPUs will probably blow away the M1 results, otherwise they'd show the competition ;)).
