    Both the iPod Touch and iPhone use the same ARM CPU.

    iPhone is clocked at 620 MHz while the iPod Touch's is clocked at 412 MHz.

    BUT, according to Wikipedia, the iPod Touch's CPU is UNDER CLOCKED from 620 to 412.

    Is there any reason to this?

    Maybe because Apple wants to keep the iPhone better then the iPod Touch.

    the ipod touch and iphone both run at the same speed acording to sysinfo.

    I think its just to save battery.

    definately battery life. they made it as fast as they needed to. The iPhone does more at once, with the phone subsystem always running, so needs more horsepower

    Well, given the SDK apps coming out midyear, it would be great to be able to have the touch's cpu @ max. It would be good to have a power option (changes cpu performance vs battery life).

    Underclocking is done for two reasons; decrease heat and less power consumption. I would guess it's to do with battery life.

    I'd rather have more CPU for ROMs

    I charge my iPod every day anyway. The battery is amazing now, I think i'll survive with good.

    This is the correct answer.

    Just to point out, iPhone has a longer battery life than the iPod Touch, of course, iPod Touch is much thinner thanks to that.

    I'd willingly sacrifice form factor for battery life. I think that people are too concerned with aesthetics rather than functionality.

    Sorry for the off-topic, back to your regularly scheduled discussion.
