Why does x86 represent 32bit when x64 represents 64bit? [closed]

Probably because the x86 line became synonymous with 32 bit processors for quite some time, while x64 was specifically a designation for 64 bit as applications and operating systems were transitioned over, and now there are software applications that require the 64 bit designation in order to run (like some VM software).

In other words, it’s more marketing than technology for the reason.
