Looks like Tensor Flow now supports ML Compute, which in turn uses the appropriate hardware. In the case of the Mac Pro, I'm guessing ML Compute is using the GPU. In the case of the Intel MacBook Pro 13", which as far as I can tell from Apple's site can't be purchased with a discrete GPU, that will be either the Intel Iris GPU, or the CPU. In the case of the M1 MacBook Pro 13", I'm assuming ML Compute prioritizes the Neural Engine over the GPU (and CPU), but don't know if there are use cases where the GPU would be preferable.
