Motherboard RAM for later models

[widEyed]

just wondering what the limitations for expandability will be for future Macs with Apple Silicon? I assume having up to 16 GB on the SoC itself has big performance advantages, but what about for bigger Macs to come, is it conceivable that they could have another (slower) level of SDRAM off the SoC elsewhere on the motherboard, even user removable/upgradeable like the Mac mini and iMac which came after considerable volume of consumer requests and reviewers dissing the Apple tax and lack of upgradability.

What about future Mac Pros? is it even possible they could have more than one M.x chip on the board. how about shared SDRAM between them?

excuse my ignorance, I stopped paying close attention to hardware specs a long time ago

Both a hybrid RAM system and just a redesigned M1 with more RAM onboard are both possibilities. But the laptops they released were already capped at 16GB. So its very likely they already have an answer for 16GB+, but are holding off on it for now for either production or testing reasons.

I'd assume multiple M1's are also very possible, but again it may be somethign they are still working out. I suspect the Mac Pro will be the last machine they update as it has the most solutions needed (multi-CPU, multo/dedicated GPU, highest RAM limits, most ports). I know a lot of places would likely love the new performance of an M1 based Mac Pro, but if its not upgradable and they cant keep adding more ram or storage or faster GPU's that is going to REALLY make them think harder on it as they will be locked to the same production time for the life of that Mac. More so if they can't add in a fibre card or other add-ons they require.
