The upcoming battery friendly ARM based windows PC will support x86 emulation 32-bit apps in near native speed. Not sure if it will support x64 now or in the future and perhaps someone can comment if this is a technical limitation or an economical or both.

- xorblurb 9y agoI think they don't support x64, and probably they never will, or at least not before a very long time. It's possible MS can leverage part of its existing WoW code with x86 on ARM64. They would have more work to do with x64 on ARM64. Plus the CPU might need special support to help things, for example I'm curious about how to efficiently emulate the stronger memory model of x86 on an ARM, and if the CPU provides help, it might be using low level tricks, reusing some bits here and there, to do the magic. Just some wild hypotheses though.
