Powerbook G4 Bench Marks - Mac Portable

Hi All, I am thinking of upgrading my Prismo and getting a G4 powerbook. I have been looking for benchmarks of the processors to compare versus price. Are there any real world results for numerical work, not commerical application like photoshop. I am interested in numerical work on the Powerbook using C code. I am not interested in graphical performance, nor screen size as I will work primarily with emacs. I only need 256 Mb RAM and minimal I/O performance. I am interested is the extra money for the L3 cache is worth it in performance? Simulations on my mathematical ...

    Default Powerbook G4 Bench Marks

    Hi All,

    I am thinking of upgrading my Prismo and getting a G4 powerbook.

    I have been looking for benchmarks of the processors to compare versus
    price. Are there any real world results for numerical work, not
    commerical application like photoshop.

    I am interested in numerical work on the Powerbook using C code. I am
    not interested in graphical performance, nor screen size as I will
    work primarily with emacs. I only need 256 Mb RAM and minimal I/O
    performance.

    I am interested is the extra money for the L3 cache is worth it in
    performance? Simulations on my mathematical models take around 8.5
    hours on my Prismo with Mac Os X 10.2.6. So I hope to drop this to
    4 hours.

    I like the Powerbooks as I can work on the program when I am
    travelling. Since I travel alot so small size 12.1 inch is good.

    Are there still heat problems with 12.1?

    I know I have alot of trade offs, so some performance figures will
    help.

    Thanks

    Prismo Stuie? Is that a Pismo with buggered colour convergence?

    I'd reckon your best bet would be to bludge a G4 and try your own code
    on it.
    If you could make the altivec processor do some of the work, you'll
    find the G4 will whoop the Pismo.
