The meaning of x86 and x64.

Why are 32bit referred to as x86 while 64bit is referred to as x64?

Answer from John[MSFT]

x86 comes from the Intel part numbering scheme for CPU chips:

8086
80186
80286
80386 (sometimes called '386)
80486
Pentium thru Pentium IV (which nominally would have been 80586).

The "X" represents the general family of xxx86.

For x64, it Is because of the 64-bits. The x is from the x86 notations.
