    Now with all these apps for the iPhone, wondering what computing power does the CPU have. Is it comparable to a G4 or G5?

    Its ~500mhz+ when on power saving mode, and the ARM processor goes to ~667 at its fastest for apps. Can't remember exact figures, but problem is a computer processor is different that these ARM processors in phones.

    Not even close. Don't compare the tiny mobile processor made to do 1 thing on a tiny screen with a full blown desktop cpu made to run a full operating system, run multitudes of different tasks, often all at the same time. They are two entirely different things.

    It's probably a very low-end G4 as far as processing power goes. Don't forget that these games are VERY scaled down compared to what you see on a console. They're still great, but the monkeys in Super Monkey Ball don't look as good as even on the PS2. There also isn't a dedicated GPU, so you lose some punch there compared to older machines.

    But we're still talking about one kick-ass phone.

    The post is coming from inside the house!
    It opens Mail, iTunes, Safari and renders web-pages a heck of a lot faster than my beloved iMac G3. So... it's faster than that.

    On a recent MacWorld podcast the iPhone developers they interviewed compared the processor in the iPhone/iPod touch (which runs under-clocked at 412MHz by the way) to be roughly similar in speed to a Wallstreet PowerBook G3 - not bad for something that fits in your palm.

    One interesting thing they discussed was that because of the iPhone's slower processor they needed to make the app as efficient as possible - the things they discovered doing this led to their desktop versions speeding up dramatically.

    In terms of megahertz the ARM processor in the iPhone is roughly equal to low-end G4 or G3. This is an extremely crude form of measurement and can't be used for any real comparison.
