Difference Between x64 and x86 Architecture - GeeksforGeeks
WEBFeb 19, 2024 · x64 is a 64-bit structure that extends the x86 structure. The time period “x64” is frequently used interchangeably with “x86-64” or “AMD64” because it became advanced with the aid of AMD as an extension of the x86 structure. Later, Intel observed this model, calling it “Intel sixty-four” or “IA-32e”.
