    It was on a similar performance level, 940xm vs 26XXqm. The difference was, 9xx cpus can be overclocked freely, easily, which thankst ot it, completely outperformed 26xx cpus, even 27xx and only lost to 28xx. soundily.

    Core i7 9xx cpus are still a great choice despite being so old.

    The comparison between Ivy and haswell is still valid, as he mentions it will be a clock for clock performance increase. If both old and new gen share same clockspeed, it is obvious the differect architecture brings this extra performance at the same clockspeed.

    I doubt they will push too much the envelope, it seems only very few of us consumers care for extreme performance.

    CUDA cores / core clock / mem clock / memory interface / 160.....?

    now thats just mean :p out with it! :D

    edit: 160 = memory bandwidth in GB/s! :)

    Well thats the specs of the 680mx.... so the tdp would be higher.

    well we already speculated that the 780M might just be a rebranded 680MX inside a 100W tdp envelope, right? so that might just fit the bill

    No 160 = TDP... :p

    But yeah that *IS* the 680MX. Hopefully it can run within the 100W TDP envelope. But it's still not going to be anything uber significant over the 680m considering clock speed is slightly less. Memory clock should OC a decent amount though, but I think the limited GPU clock may hinder that performance.

    But not according to Anadtech. :rolleyes: AnandTech - Intel's Haswell Architecture Analyzed: Building a New PC and a New Intel

    Improvements are mainly in power efficiency.

    You kidding? Overclock the core to 1 ghz and the memory as far as it can go and you have a 680. The decrease in the core clock also suggests that they lowered the voltage to fit into 100W so it probably won't overclock as well as the 680m on stock voltage but that's what overvolting is for. :D

    The only question is how hot will it run?

    We don't know how well they managed to optimize the core for lower consumption so there's no point in speculating about TDP yet. We do know however that the 680m doesn't consume the full 100w so they did have some room to play with.
