I suppose that would depend on how many of those machines were set up with Migration Assistant, which transfers nearly all the cruft from an old machine, all the way down to Homebrew packages and other CLI tools. Doesn’t really feel like a “new computer” when you’re greeted with the same desktop and console.

My anecdata last weekend was 60% to 90% JavaScript benchmarks from a loaded 15” to an M1 Air, that coupled with no fans screaming at me sure felt new.
