The thing is, we're moving from CPUs that at least had their external behaviors and interfaces documented to CPUs which are _not_. Apple has already missed plenty of opportunities to generate goodwill or even minimal assurances of interoperability, and the argument that "at least it's not as locked down as the iPhone" (where this would be outright impossible instead of just ridiculously complicated) is hardly reassuring.
- astrange 4y agoThe CPU is documented; the documentation is written by ARM.
- sharikous 4y agoANE is not, AMX is not, secure enclave is not... plus a lot of proprietary registers
- astrange 4y agoANE and SEP aren't the CPU, they're the SoC ;)
- AshamedCaptain 4y agoApple explicitly does not make an ARM CPU, they make an "Apple Silicon CPU", and the fact it currently resembles ARM (and not fully) is an implementation detail.
- pmarreck 4y agoWhat about the GPU portion?
- astrange 4y agoThat isn't the CPU.
