The only thing Apple silicon has going for it is power use and that gap is getting closed. I can't really see any reason why I would switch to Mac, it just seems like you pay a lot more for a closed expensive environment that fights you at every step.
I'll never pay anyone for a developer licence or fee either. They can sponsor me to port my software to their platform.
Is it? I recently paid $999 for a pre-build intel mini-pc system thats best case in line in perf with a M2 from four years ago. That seems roughly the same as what I'd paid for an equivalent mac mini in the past, and I thought prices for custom builds were going up quite a bit too?
But to do it literally - I'm not a low-level motherboard EE, but I'd bet you're looking at 5 to 7 figures (US $) of engineering work, to get around all the ways in which that would violate assumptions baked into the designs of the CPU, support chips, firmwares, etc.
Make a fake ram which offers write through guarantee and returns bus no matter what address is referenced. You could possibly short circuit any "is ram there" test if it just says yes for whatever size and stride got configured.
