How to distinguish 32/64 bits CPU architectures

❑ x86 CPU architecture is called 32-bit, i386 or IA-32.

❑ x64 CPU architecture is called 64-bit, x86-64, AMD64, IA-32e, EM64T or Intel64.


※ The criterion for distinguishing the 32/64 bit CPU architecture is the register size. A 32-bit CPU has a 32 bits register size.
32/64 비트를 CPU 구조를 구분하는 기준은 레지스터의 크기이다. 32 비트 CPU는 레지스터의 크기가 32 비트이다.
