Being a more modern benchmarking suite, 3DMark06 has it a different way: there is no equality between the ATI Radeon HD 2900 XT 512MB and Nvidia’s GeForce 8800 GT and GTX. The pre-overclocked G92-based cards score over 11.000 points, which is quite impressive for their rather modest price.
The GeForce 8800 GT shows a bigger effect from overclocking in the SM2.0 than in the SM3.0/HDR tests, but the latter tests prove how important the GPU’s computing capacity is when the graphics card has to process numerous complex shaders – just look at the results of the ATI Radeon HD 2900 XT.
Overclocking has the biggest effect on the performance of the GeForce 8800 in the first test, which is sensitive to the graphics card’s texturing speed. The same effect is smaller in the second test where the MSI NX8800GT OC is a mere 0.6fps ahead of the Nvidia GeForce 8800 GTX, for example.
The MSI NX8800GT OC goes neck and neck with the Nvidia GeForce 8800 GTX in the first of the SM3.0/HDR tests but the flagship card is unrivalled in the second where the number of execution subunits must be the decisive factor.
