Title is very misleading. M1 is faster than a macbook pro without discrete graphics, slower than a macbook pro with discrete graphics. But who is training models on their laptops? Any real (i.e. non-toy) machine learning model requires a desktop and Nvidia GPU, which is several orders of magnitude more powerful.
If you can't afford it (but can afford the newest Macbook Pros?), Google Colab is free. Or use other cloud based GPU providers.
I don't know what Roboflow is, but I wouldn't trust claims they have on their website given the deceptive headline.
