So there is M1, M1 Pro, M1 Max, M1 Ultra... and now there will likely be 1 more chip in the 1st gen (M1 series).
what name is bigger/better than Max/Ultra? M1 definitive?
anyways...
It looks like the final M1 chip will be essentially multiple M1 Max connected together. The M1 Ultra is essentially 2x M1 Max put together... the M1 chip in the Mac Pro would likely be 4 x M1 Max linked together... or possibly even more than 4. They might have something to reveal for like giant server replacements for cloud computing that is several M1 series chips linked together.
Definitely going to be more on that secret M1 Max feature that will be apart of a future apple event for Mac Pro.
