The M1 is their lowest end chip, I would expect it would be outperformed by their highest end chip as well as their other chips that are consuming more power.
I use the M1 every single day for my work and personal stuff, it hasn't struggled with a single thing I have thrown at it. I fully expect the high end offerings to easily compete at this point. The lack of heat generation from this chip (I have the Air, so no fan) is just something that AMD isn't able to compete with at this time. I hope it drives them all to make better products, that's what competition is for.
Edit: You really need to check the single core performance on the M1, it's besting the thread ripper you posted by a decent margin.
I fully expect these chips to be hard to handle (for AMD and Intel) when scaled.
