M3 vs other high end intel chips on code compilation generally has the higher clock speed always winning. Only with the M4 is starting to hit clock speeds nearer to high end intel chips . We are 2 generations out to probably 5ghz sustained on Apple chips.

In guhidalg's defense, they did say that the "Mac laptops feel faster" (emphasis mine) not that they are faster. There's a trick here with Macs, which is that their user interfaces for the OS and many programs are tightly integrated with the hardware which makes the UI faster--that's the "feel faster"--it's a software, not hardware thing. In cases where the software is equivalent (i.e. cross-platform compilers like GCC/Clang/Cargo) you're going to see little difference, but your OS experience is definitely snappier on Macs.

The arm architecture is also optimized for UI-like tasks, quick to start and stop processes on one of many cores with differing power constraints, whereas x86 is more for workstation-type sustained workloads
