It isn't. ARM's fixed-length instructions helped Apple achieve a wider front-end than contemporary x86 CPUs which helped, but that's about the end of the ISA differences.
Which is why all the other ARM CPUs are slower than x86 CPUs. ARM doesn't really provide an advantage. Apple's stonking huge cash and R&D budget along with Intel struggling right as TSMC is firing on all cylinders is what gives M1/M2 an advantage.
