> M1 uses TSMC high-density rather than high-performance.

Is that an actual product differentiation from TSMC? Or just observational + the fact that it's 5nm.

I'm actually curious from a chip manufacturing standpoint.

There’s actually three major version on N3 (sorry, I don’t have time to look up the similar articles on N5/7, but I think wikichip has a couple).

I remember seeing a picture of a partner list for a TSMC node with a couple dozen libraries that not only changed based on density, but also on type of chip being built.
