    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?

    Stop prating around mate.

    Bumping your question will piss people off.

  6. "8086/8088, 80286, 80386"
    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.

    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.
