M1 is ARMv8.4

v9 has a bunch of neat features that improve security and performance (+ less baggage from ARMv7 which also improves area and power)

Many of them are already optional features in later ARMv8 revisions, however.

A lot of v8.x features were added to fix mistakes in v8.

v9 brings a bunch of completely new stuff, specially in the security department.
