The updated instruction set is grouped according to architecture (i186, i286, i386, i486, i586/i686) and is referred to as (32-bit) x86 and (64-bit) x86-64 (also known as AMD64).
x86-64 is the 64-bit extended architecture of x86, its Legacy Mode preserves the entire and unaltered x86 architecture.
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.

x86 is a term used to describe a CPU instruction set compatible with the Intel 8086 and its successors, including the Pentium and others made by Intel and other companies. This is the CPU architecture used in most desktop and laptop computers. Many 21st century workstations and servers also use x86 processors.
x86-64 is the general name of a series of 64-bit processors and their associated instruction set architecture. These processors are compatible with legacy x86 software. AMD and Intel are the major manufacturers, and VIA also supported it with VIA Nano processors.
