Wrong, the majority of Apple’s thermal efficiency comes from superior design which in turn comes from the fact that they were able to design it from the ground up with no backwards compatibility requirements (since they don’t have any customers of the chip besides themselves).

This is false. Apples arm chips are compatible with the normal arm instruction set. Evidenced by Linux trivially running on it.

With AArch64 yes, but that's a relatively recent 'clean break' ISA. It's not an extension of Arm32.

Well it’s an ARM chip. it’s still not backwards compatible..
