    I presume your talking FSB to Processor clock.

    I doubt there is a fixed number. It will depend on a number of variables. A few I can think of:

    processor architecture
    memory bus width (bits)
    L1, L2, L3 caches
    clocks per cpu instruction
    the program you're running

    Generally speaking, both cpu clock and memory bus clock are both bottle necks and you want each as fast as possible, because either can slow down your system under certain circimstances.
