    Damn im so glad !

    only a few % increase going from 480 to 512! Was afraid that it would be a killer card.

    Dont get me wrong my 480 GTX's in SLI are beasts!

    The frequencies of both cards automatically dropped to 51/101/135MHz (Core/Shader/Memory) in stand-by state. The GPU voltage of 480SP GTX 480 decreased to 0.963V, while that of 512SP GTX 480 was 0.962V.
    As we had expected, the stand-by power consumption of 512SP GTX 480 was 17W higher.
    Under full load the GPU voltage of reference GTX 480 was 1.0V, while 512SP edition was 1.056V. Surprisingly, the full spec’ed GTX 480 sucked 644W power, which was 204W higher than 480SP GTX 480!
    The addition of 32 CUDA cores is not supposed to result in such significant improvement of power consumption. Considering the sample we have has yet to be improved and the increase of GPU voltage brought some negative effects, we’re not sure about the power consumption of final product.


    Also worth noting that stock clocks on 512 is 801/1600 an that when they compared to 480 they down clocked the 512 to 701/1400, so the 6% increase was only from 32 extra sp an 4 rops.

    Nice review even at this stage, still way better than the usual rumours. I wonder about some things though: will the 3 slot Accelero Xtreme Plus cooler be standard/factory cooling solutions for all 512 SP 480s and is the power consumtion bugged I mean that can not be right.

    As for the card itself, it looks good and I think the noise should be better with the 3 bigger fans. All in all I like how it shapes out and I could imagine buying one if they ever get released but I hope they fix the power consumption and give the card a proper name. Only downside is that I can't get two for SLI with this cooling solution but I guess one would be enough anyway for 1920x1200.
