    Not as far as I can tell. Also consider the fact that the K6 does _not_
    have the (now infamous) PPro/P2 fpu bug.

    The K6 is not a PPro clone.

    Not much.

    CPU Dhrystones
    ---------------------- ----------
    AMD K6/200 374838.4
    Pentium Pro 200 356929.4

    Note that K6 seems to have about 30% slower FPU (but less buggy too :-).
    If the majority of stuff you do is int, as I suspect it is, the K6 is a
    great value.
