Futuremark 3DMark06

The results are more realistic in 3DMark06: the Radeon HD 2900 XT is a little slower than the GeForce 8800 GTX while both versions of GeForce 8800 Ultra score over 11.000 points.

The GeForce 8800 Ultra is in the lead in both groups of tests at its default as well as overclocked frequencies whereas the GeForce 8800 GTX scores 154 points less than the Radeon HD 2900 XT in the SM3.0/HDR tests. Thus, the GeForce 8800 Ultra is the only supreme leader in all the 3DMark06 categories, at least at the default settings.

The Radeon HD 2900 XT falls far behind the GeForce 8800 GTS in both SM2.0 tests. The senior GeForce 8800 models are ranked according to their technical characteristics, from the GTX to the overclocked Ultra. The standard GeForce 8800 Ultra with default frequencies outperforms the GeForce 8800 GTX by about 10%. The XFX version enjoys a 14-15% advantage.

The overclocked frequencies of the XFX card bring it no benefits in the first SM3.0/HDR test where it is exactly as fast as the ordinary GeForce 8800 Ultra. Performance seems to be limited by the memory bandwidth here. There is no such limitation in the second, less demanding, test and the graphics cards are ranked in their usual order, but the gap between the GeForce 8800 GTX and the GeForce 8800 Ultra is bigger than between the GeForce 8800 Ultra and the XFX GeForce 8800 Ultra Extreme. This is also the single test where the Radeon HD 2900 XT is close to the GeForce 8800 GTX.
