Apple silicon has features specifically designed for macOS or software running on macOS. e.g.: Rosetta 2.

From Wikipedia:

One of the key reasons why Rosetta 2 provides such a high level of translation efficiency is the support of x86-64 memory ordering in the M1 SoC.[12] The SoC also has dedicated instructions for computing x86 flags.

So, Apple always adds one more thing to their hardware to enable their magic.
