yes, the "base" is the core so to speak, but Apple has been using SOC, meaning the entire Mx/Pro/max is an entire chip in itself. So from that perspective your first volume chip will be the base.Yes but my understanding is that the “heart” of the max/ultra/whatever else they’re called is the base M. So given that, I don’t think they’d be using N3B because longer term that’s a complete dead end.
They’re likely holding off for volume production of N3E for the entirety of the M series and N3B designs are not compatible to simply be “switched over” to the N3E process.
Am I wrong about the base M’a being the building block of the upper series? I could be.
and yes, you cannot "switch" from N3B to N3E, it is a new/different design
