    thats because it is clocked slower :)

    It does, just most likely under clocked in the 600MHz to 800MHz range.

    Same CPU but that doesn't mean running at the same speed

    Apple has a long history if underclocking chips in the name if battery life

    Yeah, I'd bet the same.

    I'd be very interested to see the Android 2.2 browser up against the iP4 browser, considering the Nexus One smoked the iPad at Google's I/O.

    that would be a pretty good comparison. the faster response of the iP4 (download and latency) might give it just that little bit of an edge.

    also i hear the Nokia N900 is not @1GHz? not bad!

    I ran SunSpider Javascript Benchmark and 3D Benchmark on the iPad and iPhone 4.

    The iPad ran SunSpider 1.3% faster overall,
    and 3D Benchmark's average FPS was 2.3% faster.

    If you breakdown SunSpider into its 9 elements, there were things the iPad did faster and some things it did slower.

    I would have run Geekbench for iPhone on both but it only runs on the iPhone (for now).

    BTW, the iPhone 4 runs SunSpider 27% faster than the Sprint EVO 4G.

    That's very interesting, good work. So if the froyo benchmarks I've seen online are accurate, google have got the browser crown for now.

    Evo with froyo will get roughly the same results as the nexus one benchmarks. The tech is very similar.

    While the iPhone 4 and iPad have same processor, the A4 chip in the iPhone is underclock. The iPad's A4 runs at a full 1GZ. So the iPhone 4 (to conserve battery) runs probably around 700-750.

    Obviously Apple also did this to create enough of a gap in performance between the iPad and the iPhone 4. I believe even though the iPad has 256MB RAM/1GZ speed, it still runs 20% faster than the iPhone 4.

    I own both iPad and iPhone 4. And the iPad is noticeably still faster at loading webpages than the iPhone 4.

    Can you imagine this phone running at full throttle? Battery would be dead within an hour.

    There would definitely be a hit, but I'd say you're talking in the vicinity of an hour to an hour and a half off the phone's talktime rating. Which would bring it in line with the likes of the HTC Desire.

    But an hour of talktime can translate to two or three hours of real-world use (or more depending on the usage)

    Does it even matter?

    This thing is rediculously fast compared to my 3G.

    I zip through the same neurotic tasks I used to do in half the time. Then I sit there thinking WTF, I actually have to find more things to do! LOL
