Why is it likely going to be on 5nm? 3nm has been in risk production for months now, which would line up with enough lead time for full production for normal Mac refreshes early fall.
That’s just the rumors. Rumor is apple didn’t buy the rights to first run of 3nm. Rumor is intel actually did for some of their new CPUs
Maybe their GPUs that they keep teasing but even that's a stretch, IMO.
