ARMs behavior lately is pushing a lot of riscv investment, my prediction is that Apple will migrate away from ARM 10years from now to something they can self-control, like riscv with some Apple-only extensions
Apple has shifted its processor technology every 11 years for its desktop machines.
But it has kept with ARM on iPhone for the last 15, so...
Anyhow, it is hard to predict with accuracy that far out.
That said, the first indications of a shift would be Apple adopting the RISC-V chip on the low end, things like the Apple Watch and Air Pods. Apple Watch has been using a 7N ARM chip since 2018 at nearly the same speed -- it seems like it doesn't need to be getter faster at each generation like the iPhone or MacBooks do. If adoption happens in this peripheral areas, then it is likely to move upstream to other devices over time.
Apple was an original investor in ARM and used ARM processors for Newton and a bunch of things like, I think, some of the time capsules.
I believe they are using RISC V internally, for some small things that are invisible to the end user. It would make sense, just to get a feel for it in case it matters down the road.
Its crazy to think about where things will be 10 years from now. Will we have beached 1nm? Then what? Is there actually a feasible roadmap for after that?
