...And you think there'll never be an M2? Or M1X, or whatever branding Apple decides to put on their 32/64/128/???-core version that supports terabytes of RAM?
I think the open question about the Mac Pro is the expandability. The trash can Mac Pro didn't do well and they went back with something with expansion slots. Is it worth it to Apple to build out and support everything necessary on the M1 platform for one low-margin line of computers? We'll find out in the next year.
Even the 27" iMac has a 128 GB RAM SKU, so they're going to need to build a chip supporting external RAM regardless. External PCIe support already exists thanks to thunderbolt. So the architecture will be there, it'll just be a question of how expensive it is to scale up.
Gigacore
16GB should be enough for everyone
Until they publicly show they can make such a thing, there will be some scepticism
You realize Apple is designing against more advanced nodes than intel - and from where I stand intel has nothing competitive in small form factors
Why? Apple just demonstrated that they could do something that had previously been considered unrealistic. They've also been demonstrating massive annual performance gains for many years. For people who have been watching closely, they should have some credibility by now.
