    People are saying the 7970m is a downclocked 7870. the 580m has been leaked.

    A downclocked 7870 at 7970m clocks would score roughly 6000-7000 gpu score in 3dmark 11. The 680m scores 4200-4800.

    Why does the 7970m perform so much better?

    what? which 7870 scores 7k 3dmark11? also downclocked, as in 580m is a downclocked 560Ti, doesn't score as much as 560Ti

    Not exactly

    even 7870 is not a 7000 gpu score with stock clocks, let alone downclocks

    See this chart (not 100% accurate for laptops duo the weaker laptops cpu)

    It's quite safe to say that both cards will end up being 5xxx~ with slight advantage to the 7970m if the leaked benchmarks are accurate

    In plain english, both cards will be around equal to desktop equivalent of

    6970~ or GTX 480~ GTX 570~ they will be around that range only

    680M was 4.9k in the leaked benchmark, and that was probably an engineering sample with some AMD quality drivers.

    Just wait for 7970m benchmarks. The desktop version of their new cards was not at all impressive, perhaps they have done better in the mobile cards, but I won't hold my breath.

    What the? The current HD7000 series, specially the 7870, are among the best deals in price/performance ratio we have seen in a while.

    If anything, nvidia has been quite late this time around. They always held the performance crown even before the HD2000 series which was the moment AMD stopped being competitive at the high end.

    this time, the current top card of nvidia barely edges the AMD card, by a much lower margin than previous generations. Not only that, but they haven't introduced yet competing lower end GPUs which is the bulk of the customers. this is only based on actual products available.

    Seriously... both GTX680 and HD7970 when overclocked, sometimes reach similar numbers to the GTX590 and HD6990.... thats quite a feat.

    Looking at TDP though, it is obvious the new architecture combined with a ceiling of 100w can yield a decent performance boost. This applies to both AMD and Nvidia. If they will exploit it, it remains to be seen.

    As for performance expectations, rumored specs of both cards (680m and 7970m) leave the AMD card at an advantage. It remains to be seen how true this will end being.

    I say a decent jump in performance is due already from both vendors. We have been stuck for a while in a small increment.

    I also heard that Amd has a bad driver compare to Nvdia. Is this true?
