x64 servers and PCs are compatible because all of them adhere to an architectural standard backed by a suite of a suite of compatibility tests defined by Microsoft: https://learn.microsoft.com/en-us/windows-hardware/design/co... and https://learn.microsoft.com/en-us/windows-hardware/test/hlk/ . The ARM world has no similar agreed on standard.
