    SemiAccurate have got hold of a few performance figures for the Geforce GTX 480. Earlier rumours indicated at the GTX 480 being upto 60% faster than the HD 5870. However, SemiAccurate's sources report that the GTX 480, on average, will end up being a mere 5% faster than the HD 5870 at higher resolutions, despite costing Nvidia a lot more to manufacture. The GTX 470 was not tested in these internal evaluations, and will most certainly end up slower than the HD 5870.

    The GTX 480 is set to contain 512 shaders, as initially expected, but far lower clocks than the clock target of 750/1500 Mhz. Instead, it will be clocked betwen 600-625 MHz for the core, 1200-1250 MHz for the shaders (or, as Nvidia calls it, CUDA cores).

    That put's it at about GTX295 speeds, faster then the HD5870, that doesn't sound bad.

    I could also imagine board partners with custom PCB and clocks, like XFX Black, EVGA FTW, BFG OCFU and what not.

    What do you mean, even in that artciel they say:

    "
    Nvidia was claiming 60 percent more performance than Cypress last fall. That quickly dropped to 40 percent better, and at CES, Nvidia could only show very select snippets of games and benchmarks that were picked to show off its architectural strengths. Those maxed out at about 60 percent better than Cypress, so consider them a best case.

    If that 60 percent was from a fully working 512 shader, 750/1500MHz Fermi GF100, likely the case at 280W power draw, than a 448 shader 600/1200MHz GPU would have 87.5 percent of the shaders and 80 percent of the clock. 160 * 0.875 * 0.8 = 112 percent of the performance of ATI's Cypress. This is well within range of a mildly updated and refreshed Cypress chip. Don't forget that ATI has a dual Cypress board on the market, something that Fermi GF100 can't hope to touch for performance."

    That sounds to me like the gtx470 will even be 12% faster than the 5870, sounds awesome to me.

    12% is pretty small in comparison to nVIDIA's former claim of 60%.

    that 12% is for the 470...which is the 448 shader model, the 480 could easily be 40% faster when like the link said, the benchmarks were 60% better which would be the best case scenario, 40% faster than a 5870 would be an awesome upgrade.

    Like I said, the 480 will be quite a bit faster than the 470

    I just hope that all this wait wasn't for nothing. If the 480 performs as it was meant to, I'm buying two of em which should keep my happy for two years, at which point I'll be in college somewhere in Europe or in Canada

    Only one way to find out. Wait until it's released, then we can talk performance numbers. :D

    Wasn't semiaccurate reporting that the 480 was not going to have 512 shaders only a few months ago? Now they are?

    http://www.semiaccurate.com/2009/12/21/nvidia-castrates-fermi-448sps/

    Did Charlie ever admit to being wrong about that? No.

    I don't know why Charlie gets attention from anyone, his articles should be banned from this forum. Even if he is right about 50% of the time, it's pretty obvious that he has an agenda against Nvidia, which is just garbage reporting.

    I agree, he's one of the worst I've read. But it fuels discussion. Gives us something to do while we wait. So I don't know about banning it.

    Besides, he's certainly right about SOME things, maybe this is one? Maybe it's not. Who knows. Something to do.

    It's a good thing that nvidia learned from their past mistakes and took the lesson well, now there will never be a GeForce FX 2.0

    /sarcasm

    nVidia fun fact: The GTX 400 series will have 25% lowered clocks then planned but use up 50% more power and have double the TDP than the previous generation! We call that INNOVATION!

    That actually makes big sense, No wonder why Nvidia has ben Publicing Fermi more as a CPGPU than a Gaming CPU. I don't think that people will be able to overclock it much, without Liquid or Nitrogen cooling, it seems that they are going to end quite hot with stock coolers, If they lowered the speeds so much it means that they are having big thermal problems, otherwise they would release it at full speed to take the Speed Crown Back.
    Ati is around the corner to release updated versions of the 5xxx cards, like The 4890. soo Its posible that Ati will keep its performance Crown.

    We have no concrete information... How can you assume we need H2O to overclock ?
    Sash, how are you certain of the lowered clocks and increased TDP ?
    Even if this GPU fails big time in terms of gaming, it's still a huge leap forward for Tesla and supercomputing. Also, Tegra 2 will be making nVidia a boatload of cash so don't worry, nV ain't going bankrupt just yet

    Why skip a generation in naming the thing if performance is so-so? It wouldn't surprise me if the Fermi were only 5% faster with PhysX turned on...but we'll see when it gets here.

    Here is another example of Charlie just flat out lying.
