Thank you. That makes sense. The complexity of these modern processors is shocking. It’s a miracle they ever work at all. Hiding the AMX instructions behind an API allows Apple to fix some hardware bugs with software, such as by not using a particular sequence of instructions.
The AMX engine must run at the same clock frequency as the 4 P cores or 2 E cores it is connected to. If one P core starts doing a lot of AMX operations, I wonder if the clock frequency of the remaining 3 P cores gets reduced, sort of like the clock frequency gets reduced when using AVX512 instructions on a Xeon processor.
