This is hilarious. You might have missed that the benchmark was missing Nvidia (or even AMD) graphics cards; I can't think of a lower bar for comparing ML performance than against Intel GPUs - perhaps Intel CPUs? While Apple has brilliant engineering, the M1 cannot possibly outperform the obscene number of transistors Nvidia & AMD throw at the task, even in older, mid-range cards. Not to mention power dissipation.
If you're dabbling, you're better off with Google's Colab[1] which has (free) hardware acceleration which is roughly on par with my 3-year-old RX580 for my Tensorflow projects. Colab will work on anything that can run a browser.
