The Apple M series is not ARM based. It’s Apple’s own RISC architecture.
M1s through M3s run ARMv8-A instructions. They’re ARM chips.
What you might be thinking of is that Apple has an architectural license, that is, they are allowed to implement their own logic to implement the ARM instruction set, not just permission to etch existing designs into silicon. Qualcomm, NVidia, Samsung, AMD, Intel, all hold such a license. How much use they actually make of that is a different question, e.g. AMD doesn’t currently ship any ARM designs of their own I think and the platform processor that comes in every Ryzen etc. is a single “barely not a microprocessor” (Cortex A5) core straight off ARM’s design shelves, K12 never made it to the market.
You’re right about the future being RISC-V, though, ARM pretty much fucked themselves with that Qualcomm debacle. Android and android apps by and large don’t care what architecture they run on, RISC-V already pretty much ate the microcontroller market (unless you need backward compatibility for some reason, heck, there’s still new Z80s getting etched) and android devices are a real good spot to grow. Still going to take a hot while before RISC-V appears on the desktop proper, though – performance-wise server loads will be first, and sitting in front of it office thin clients will be first. Maybe, maybe, GPUs. That’d certainly be interesting, the GPU being simply vector cores with a slim insn extension for some specialised functionality.
Thanks for the clarification. I wonder if/when Microsoft is going to hop on the RISC train. They did a crap job trying themselves at a ARM version a few years back and gave up. A RISC Surface with a compatible Windows 13 and proper binary translator (like Apple did with Rosetta) would shake the PC market real good!
