Advanced Performance Extensions expand the entire x86 instruction set with access to more registers and adds various new features that improve general-purpose performance.
Apple and Microsoft are doing a pretty good job at translating x86 to ARM. It’s not perfect but I haven’t really faced any application that just failed to run (to be fair I use pretty popular applications so maybe there’s a bias there).

The biggest advantage is backwards compatibility with existing x86 software. You will lose that with a switch to ARM.
