Absolutely ridiculous. No, Apple did not juice the M1 by giving it better cooling than x86. Quite the opposite, they took a big chunk of their design+process wins to the bank and exchanged them for even cooler and quieter operation because that's what they wanted all along. Cool and quiet was a deliverable.

It's absurd to point out that apple could have gotten higher perf from x86 at higher power as if it's some kind of win for intel. Yes, obviously they could have, that's true of every chip ever. They could take it even further and cool every macbook with liquid nitrogen and require lugging around a huge tank of the stuff just to read your email! They don't, because that's dumb. Apple goes even further than most laptop manufacturers and thinks that hissing fans and low battery life are dumb too. This leads them to low power as a design constraint and what matters is what performance a chip can deliver within that constraint. That's the perspective from which the M1 was designed and that's the perspective from which it delivered in spades.
