    Yeah, you read it right the first time. Just wanted to know how the core 2 duo desktop processors compare to the core 2 duo laptop processors. Confused as to why core 2 duo laptop is only marginally better than core duo when core 2 duo desktop annihalates pentium D. Was core duo simply a less-developed merom or are the core 2 duo desktop processors much better than the laptop version?

    Well to start with core duo was a better and more efficient design than pentium D.
    Add to that the fact that there is no FSB difference between CD and C2D for laptops.

    And the results are expected.

    Edit: Also the desktop chips run at a higher frequency.

    The Pentium D was using a failed architecture, while the CoreDuo and Core2Duo are decendents of the Pentium M, which funny enough has more in common with a Pentium 3 than a Pentium 4. Anyway, basically both Conroe and Merom come from Yonah, Dothan, etc.

    The laptop Core 2 Duo is a bit slower than the desktop one (mainly just because it's got a 667Mhz FSB while the desktop one has a 1066Mhz FSB). It's also generally got lower clock speeds (to keep the heat down).

    As others have said, Core Duo and Core 2 Duo are much more similar than the Pentium-D and Core 2 Duo.

    If you rated them out of 10, it'd go something like this:

    Pentium-D = 4
    Core Duo = 8
    Core 2 Duo mobile = 9
    Core 2 Duo desktop = 10

    The reason that there's such a big difference between the Pentium-D and desktop Core 2 Duo isn't that the Core 2 Duo is particularly fast - it's just because the Pentium-D was pathetic. There's a small difference between Core Duo and the mobile Core 2 Duo (Merom) because Core Duo was already very quick - Merom is just a small update with minor improvements.

    Yeah if you think core 2 lootgs good now, wait untill Santa Rosa comes out. The FSB will be faster, and with a whole new chipset and socket, Core 2 will really show its true colors.
