We care about the TDP, which can be improved in various ways, not just moving to 5nm. Physical size in a phone or whatever is small enough, we don't care about smaller chips. The amount of space saved is negligible.

It's never been just about phones. These chips go into all kinds of products, some of them with real thermal and size restrictions.

TDP = thermals, which I did mention. You can reduce thermals in other ways, not just smaller features.

Size is small enough for anything consumers care about, even watches.
