Actually, you have it backwards.
x86 means 32 bit and refers to a general class of processors (remember the
8086/8088, 80286, 80386, etc.?).
x64 refers to 64 bit architecture.

"8086/8088, 80286, 80386"
What's that?

They are Intel microprocessor models from years ago.

So "x86" refers to the series of Intel processors based on that
architecture. Originally they were 16-bit, but they became 32-bit. (We
could argue about exactly what is meant by '16 bit' and '32 bit', but it's
too anal for now).

I haven't heard the term "x64", but it obviously refers to Intel's current
64-bit range.

Get onto google or Wikipedia for Christ's sake.

Give credit where credit is due. Since AMD came out with 64 bit eXtensions
to the x86 type processors, x64 is an AMD invention, not an Intel invention.

Are you saying AMD is responsible for x64 being used
to distinguish 64-bit, or that they created the 64-bit
processor? If you mean the latter, you're wrong.

AMD is responsible for the 64-bit EXTENSIONS to the x86 architecture.
Which Intel then licensed from AMD.
