    "There isn't much difference between the old and new version of the A5: an "x" in the name and an extra 0.2 GHz clock speed."

    They are claiming a .2ghz ghz clock bump for A5X.. This is good news if true, better than thinking the iPad3 would crank cpu cycles just as fast as the iPad2.

    I noticed too. I wonder where they got that from.

    Seems like something benchmarks would pick up and tear downs would not, so I'd trust the benchmarks for now.

    It would be a nice surprise though, guess we'll find out eventually.

    More importantly, why did the Geekbench fail to show any gains in the report and the actual bench.

    iFixit also falsified the amount of ram in the iPad2 last year.. claiming 1gb.. but then ended up finding out they were reading the codes on the RAM wrong and totaling up to 512mb instead.

    This could be another one of those situations..

    ----------

    Could be a programming flag to trigger the iPad into "boosted performance" mode perhaps?

    Just a stab in the dark :p

    IIRC the iPad 2's processor was actually underclocked to 0.8ghz, which would explain the geekbench showing at 1ghz for the A5X chip.

    Does Apple have a history of underclocking? They wouldn't be the first.

    HP put a 1.5GHz CPU in the TouchPad but had it locked to 1GHz. (though it was unlockable using preware)

    Apple own website under tech specs says 1ghz dual core for iPad2. I doubt it's underclocked.. I am sure it's able to govern itself to save battery when not doing anything cpu intense, though like most modern CPUs.

    Edit: Tried to provide Apple link but it's since been removed now that the iPad3 is out. The iPad2 specs have been removed (link now redirects to iPad3)

    yeah a lot of companies do underclock now, easy way to manage power

    Who cares about the clock speed? Look at the size of that battery :eek:

    And now the 1.2ghz claim has been REMOVED from iFixit.. Can anybody edit these documents on iFixit? Seems like they are allowing folks to just say whatever they desire about the parts now.

    yeah i just checked the apple website, but now i think about it, I just think the ipad 2 and im sure the ipad 3 will dynamically underclock, it was the A5 in the 4s i was thinking of that was undercloked to 800mhz

    ----------

    yeah everything can be edited on it at the moment :confused:

    People are trolling iFixit.. If you have an account you can edit the info from the looks of it.
