x86-64 is the 64-bit extended architecture of x86, its Legacy Mode preserves the entire and unaltered x86 architecture.
Intel adopted the 64-bit computing bit architecture in 2004 with the later versions of the Prescott Pentium 4. The different versions are backward-compatible, meaning that a 32-bit x86 CPU can run a 32-bit or 16-bit operating system, and a 64-bit x86 CPU can run a 16, 32, or 64-bit operating system.

x86-64 (also called x86_64, x64, or amd64) is the 64-bit CPU architecture that is used in Intel and AMD processors. It is an extension to the 32-bit x86 (i386) architecture. The x86-64 architecture is used in most CPUs for home computers and servers in use today. It is incompatible with the ARM64 architecture, which is in use in smartphones ...
