    Has anyone tried that true speed thingy command on their Powerbook G4. If you can, please try it and post it here. I am very interested.

    What's the true speed thingy command? I'd run it if I knew what it was. :D

    what type of benchmark are u looking for any apps in particular you want to test

    I think he talking about that UNIX command that tells you the clock speed of t he processor.

    Thank you BillClinton..I was talking about that....
    I was wondering if someone that had the new 1.5 Ghz 17" PB w/ either 64 MB or 128 Video Ram could test it out. And please tell me how much ram you have..to see if that matters too.

    Cause I read someone on the board had a 1.0 ghz g4 but it only read it at 550 mhz.

    I have the exact same system you have but with 1 gig of ram. I scored 135 on xBench. This thing purrs.... :D

    Don't be worried about the command for finding out processor speed. The inconsistency only exists on 867mhz and 1Ghz Titanium Powerbooks. The only problem from this is that readout, the processor is actually running at 1ghz.

    That would be because the person has his/her energy saver prefs set to "reduced" this causes the PB to run at half speed... saves battery life....

    Good. I was getting worried for a second - I have a 1Ghz PB! :eek:

    It's a unix command which measures the "true frequency" of the processor. Processors are overclocked to a stable point. The "true frequency" is the speed prior to overclocking. For example, my 15" TiBook (1 GHz)'s "true frequency" is 667 MHz.

    One option is to download "onyx." It's free and will automatically check.

    The unix command you can run in Terminal is:

    sysctl hw.cpufrequency

    I did that and it said 1499999994. and on reduced speed it says.... the same exact thing.

    Im using a 17" powerbook with 128vr and 1.5 gigs of ram

    I've ran the skidmarksGT program (installed with dev tool, and chud) and the benchs your cpu against a 1.0 Ghz G4

    on auto my pb 12" 1.33 gets

    int: 1.0
    float: 1.33
    vec: 1.33

    on high

    int: 1.33
    float: 1.33
    vec: 1.33

    on low

    int: .667
    float: .667
    vec: .667
  14. macrumors 6502a


    hw.cpufrequency: 700000000

    Looks exactly right on mine, since my processor was sold as a 700mhz part. Now, if only I was gutsy enough to crack this baby open and solder the jumpers to take it up around 1.3ghz... :cool:

    mine says: 1066666664 on reduced (rounded off is 1.07ghz which "about this mac" says my 12in ibook is). Same result for highest.
