- my123 6y agoAnd Apple M1 implements AMX2, not the original AMX in the A13. I'm not sure if Apple plans to ever maintain AMX compatibility across CPU versions...
- duskwuff 6y agoYou've hit on an important point here. As soon as Apple documents one of their CPU extensions, they've put themselves in the position of having to support it long-term. Leaving it undocumented gives them the freedom to make breaking changes from one CPU generation to the next -- hopefully with the end goal of deciding on an implementation and documenting the end result.
