My M1 MBA is measurably faster than the i9 MBP it replaced in several purely software tasks. At the very least it performs on par with the i9.

There's plenty of ARM-specific optimization in macOS that gives boosts to M1s over Intel but the chips are just faster for many tasks than Intel.

Since Apple has been relying on Intel processors for many years now, I'd bet they've spent more time optimizing MacOS for Intel at this point. On the other hand, iOS has given them a quick way to transfer optimization knowledge.

Keep in mind a lot of the core libraries on macOS and iOS have been shared since the inception of iOS. The kernel, CoreFoundation, and FoundationKit are on both platforms. There's also a bunch of other shared frameworks even before Catalyst. So much of macOS's foundational code has been running and optimized for ARM almost as long as Apple has been using Intel.
