GeForce GTX 400 Series Performance Expectations Hit the Web
A little earlier this month, NVIDIA tweeted that it would formally unveil the GeForce GTX 400 series graphics cards, NVIDIA's DirectX 11 generation GPUs, at the PAX East gaming event in Boston (MA), United States, on the 26th of March. That's a little under a month's time from now. In its run up, sources that have access to samples of the graphics cards seem to be drawing their "performance expectations" among other details tricking in.
Both the GeForce GTX 480 and GTX 470 graphics cards are based on NVIDIA's GF100 silicon, which physically packs 512 CUDA cores, 16 geometry units, 64 TMUs, 48 ROPs, and a 384-bit GDDR5 memory interface. While the GTX 480 is a full-featured part, the GTX 470 is slightly watered-down, with probably 448 or 480 CUDA cores enabled, and a slightly narrower memory interface, probably 320-bit GDDR5. Sources tell DonanimHaber that the GeForce GTX 470 performs somewhere between the ATI Radeon HD 5850 and Radeon HD 5870. This part is said to have a power draw of 300W. The GeForce GTX 480, on the other hand, is expected to perform on-par with the GeForce GTX 295 - at least in existing (present-generation) applications. A recent listing by an online store for a pre-order, put the GTX 480 at US $699.

And test have shown that current 58xx cards benefit from more memory bandwidth when OCing, suggesting that the 256bit bus is indeed a bottleneck. That can be achieved either thru higher memory clocks, or a wider bus if they wanted to stamp out a new core. Both add heat and power, so the point is moot.
And btw, the 2900 outperformed the 3870 when OCing, and part of that reason was the wider bus. That's why all of the top ATI scores were still done with 2900 at that time, and not the 3870.
2900 was power inefficient mostly because of the package size, and it's high current leakage, not because of bus width.
my cpu is my bottleneck imo... i miss the i7 920 @ 4ghz
For over 50 fps, nada...
I feel no lagg or stuff like that with a PH II 940 @ stock hoho...
All the o.c. forums are saying that o.c. the RAM of current 57xx and 58xx is useless, since it provides very little performance gain, even when using liquid cooling or sub-zero custom H2/ He/N2/etc cooling. The main performer is only the GPU, so where did you got your informations, mind if I ask??:shadedshu
in anycase, waiting is always the hardest part :D
If this info is true - they should Ship these cards with Doom 5 ;)
From a 3d modellers perspective, i want some nice open ATi powered renderer :D, make use of that raw power.
Though, im still stuck, due to monetary reasons, on my old X1950Pro. :(
the card I have isn't horrid, can still play quite a few games relatively well, older games obviously but still.
Nvidia will poop fermi and it'll either be the shit or be diarrhea that just runs down the drain.
