    >>> Currently the A9 is in PPC G4 territory performance wise.

    >> which clock rate in G4 do you think a 1.2 GHz (which I think is the

    > I believe they're quite similar clock for clock.

    Also here, found some NBench figures of both to compare.

    Cortex-A9: http://www.powerdeveloper.org/forums/viewtopic.php?p=14836#14836
    G4: http://amigadev.free.fr/powerpc/nbench.html

    Result scores (for 1.0 GHz each):

    Cortex-A9 (one core of dual-core OMAP4):
    - MEMORY: 6.52
    - INTEGER: 6.19
    - FLOATING-POINT: 6.82
    - BYTEMARK INTEGER: 25.4
    - BYTEMARK FLOATING-POINT: 12.3

    G4 (scaled from 400 MHz | scaled from 1.4 GHz | scaled from 1.5 GHz*):
    - MEMORY: 7.49 | 5.76 | 4.49
    - INTEGER: 6.69 | 8.27 | 5.76
    - FLOATING-POINT: 9.24 | 6.47 | 9.02
    - BYTEMARK INTEGER: 20.7 *
    - BYTEMARK FLOATING-POINT: 16.3 *
