The rumor I read was the entire M2 line was designed for N3 and then that got delayed so they backported to N5P.

Bigger chips have much worse yields, which is why phone chips get the latest nodes first. No way they launch 3nm with M2 Max. I was expecting 3nm A16 and 5nm M2 Max for release this fall and then the 3nm M3 progression next year. But they n
