Back in June 2021, Microsoft announced ARM64EC for Windows 11. Officially, it was called a new way to get near-native performance from existing x64 applications on ARM platforms — even if you called plug-ins and dependencies that didn’t yet support that footprint. Now, a year later, ARM64EC is finally getting more complete support for Windows 11.
Of course, on Windows on ARM devices, the performance of native ARM code is still slightly better.
Microsoft’s idea, however, is to improve ARM performance through continuous codebase updates, but without losing any features in the process.
