The emulated version beats the native version some times. Either the emulator is very good or the ARM build isn't optimized too much.

The compiler is also a factor, as MSVC's ARM64 backend is less mature than the x64 backend, while the xtajit(64) emulators in Windows were written by emulation veterans. But even then, I've typically seen a ~25% penalty between a native optimized ARM64 build and an emulated optimized x64 build. Major optimized code paths being disabled or suboptimal in the ARM64 port would definitely be more plausible, especially in licensed third-party libraries.
