    1.6 GHz CPU <-> 533 MHz FSB
    1.8 GHz CPU <-> 600 MHz FSB
    1.9 GHz CPU <-> 633 MHz FSB
    2.0 GHz CPU <-> 667 MHz FSB
    2.1 GHz CPU <-> 700 MHz FSB

    So FSB clock rate is always ⅓ of CPU clock rate on all G5 iMacs (as was already written), unless the "ratio" has been tampered with.

    iMac G5 iSight also has U4/CPC945. Besides, U3/U3H/CPC925 is also used in PowerMac G5 AGP ;-)
