    what exactly is the difference between the two chips? If any.

    Is there any extra benefit of the DDR 2700 ram in the dual 1.25s?

    The only change that I would predict would be the move to a 166MHz system bus and an ability to clock slightly higher. Motorola hasn't yet updated their site with information on the 7455, so one could presume that Apple is preventing Motorola from releasing such information to the public. Quite possibly, the 7455 has clocked to 1.33 or 1.4GHz, but due to an agreement with Apple, Motorola must withold such information until faster PowerMacs are shipping.

    Eh, more than likely there is very little difference.

    moto is too powerful to have apple control them, but maybe moto agreed to this, who knows?

    i think apple has been the one wanting to move forward and it has been moto that has slowed things down

    we should be at 2 ghz right now...btw, amd just passed 2 ghz recently

    Where has this "7455A" idea come from? Link?


    If the 7455 has made it to 1.33ghz to 1.4ghz, then why do you think it took Apple so long to ship 1.25's? I think we can conclude that only a very small number of chips clock above 1.25ghz.

    Interesting pic.

    Not that I have any reason to disbelieve this pic, but has anyone done the usual close-up examinations, looking for photoshopping such as Toms Hardware got caught doing with an "exclusive preview" of unreleased P4's?
