What's interesting is Dell is shipping machines at top end with chips from generally older / slower nodes. Somehow Apple has some kind of lock on a lot of capacity at TSMC at the top end of the node range.

That XPS 15" is probably running a comet lake chip.

Ie, 14mm, launched in 2019

That node size (less the ++'s) goes back to Skylake (when it was amazing actually) which is from 2015.
