    Intel® Core™ 2 Duo processor - relative processor power?

    So i'm looking at a laptop with Intel® Centrino® Duo mobile technology with Intel® Core™ 2 Duo processor T7400 (2.16 GHz and 667 MHz FSB)

    And right now i've got a Pentium M centrino 1.6Ghz

    is the new duo like 2x2.16Ghz ? or what

    New Duo will be 2x2.16ghz (2 cores) with a larger cache

    so it'd literally be over 3 times the clock speed? or processing power?

    sounds crazy to have 4.32Ghz on an ultra-portable laptop

    wow, its only just been 2 years since mine was impressive, can't believe they've managed to make something even smaller and lighter with 4x the processor

    strangely though, graphics card is still a 128mb geforce turbocache type. you'd think they'd at least make it 128mb of dedicated ram or something

    Technically its not 4.32Ghz, you dont just add the speed together.

    Think of it as being able to do more at once, for example 1 person building a house will take a while, add a 2nd person and it will get things done faster.

    ok so is any advantage over single cores when playing games considering they are just a single application normally? disregard the gfx card

    It allows the OS to assign system processes to the unloaded core - allowing true 100% utilisation of the single core by a single app

    A core 2 chip is probably ~20-30% faster than pentium M clock for clock anyway. Add on top of that you're increasing the clock speed 35% and you've got a pretty good increase even without the second core.

    Expect multithreaded games soon. Also, I have a C2D and a lot of the time both cores are loaded during games, so it must be useful.

    technically not quite there
    both cores cant work on the same process at once, but both people can build a house at once.

    Think about peeling carrots and potatoes. One person has to peel both carrots and potatoes, whereas two people can split the workload, one peeling carrots and one peeling potatoes. Decreasing the time it takes to complete both tasks.

    Some apps don't take advantage of it. So while one guy is peeling carrots the other guy stands there watching him.

    Another point is that the new chips are less power hungry so easier on the battery.
