Added with x86-64. These instructions can only be encoded in 64 bit mode. They fall in four groups: original instructions that reuse existing opcodes for a different purpose (MOVSXD replacing ARPL) original instructions with new opcodes (SWAPGS) existing instructions extended to a 64 bit address size (JRCXZ)

x86 assembly language is the name for the family of assembly languages which provide some level of backward compatibility with CPUs back to the Intel 8008 microprocessor, which was launched in April 1972. [1] [2] It is used to produce object code for the x86 class of processors.
X64. 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. They call their own 64-bit processors AMD64, Intel64 and VIA x86-64 ...
