Microsoft uses it on some of their Surface laptops. It has software emulation of x86 instructions on ARM hardware. x64 support is coming soon. Apple has their own version of such support named Rosetta 2, it uses a combination of static recompilation and emulation to run x64 macOS apps on ARM hardware. Both systems have about 20-40% performance hit when emulating x86/x64 on ARM.
