This one goes into the weeds, but I think hits the nail on the head for the processor for the Mac Pro. It has to be a dual ultra, but that means likely a M2 dual Ultra, the M2 Extreme.
I am still not sure on the expandable ram, as it would be so much slower than the RAM in the chip, but pci expansion does make sense for so many things. And all the extra thunderbolt they could add.
Not part of this video, but what if this is right and it is a smaller MacPro and the processor is on a daughter card that could be upgraded, leaving the pci slots and extra ram if that is workable. That could be an ”upgradeable” Mac Pro for sure.
Well the Mac Studio has gotten me excited for the Mac Pro, though if it really is an M2, I think WWDC might ge pushing it, and the 2023 rumors may be true.
