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:
80386 (sometimes called '386)
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.
