Mass Labelling Hysteria
Software vendors named their compatibility labels very badly, and thus caused a lot of confusion
x86 or x32
Supposed to mark CPU’s that use x86 instruction set. But commonly used to mark 32bit software. Can store values
x64
Used to mark that this application or operating system is compatible with their 64bit CPU Can store values
x86-64
All x64 processors already use the x86 instruction set, so in essence, this is the exact same label as x64
