NVIDIA GeForce 7900 GTX Review

3DMark05

3DMark05 measures performance by simulating DirectX 9.0c games, i.e., using the new Shader 3.0 model. This programming model is used by Far Cry game and other games to be launched in the future. This new programming model is used by GeForce 6 and 7 series from NVIDIA and Radeon X1000 series from ATI.

We run this program in three resolutions, 1024x768x32, 1280x1024x32 and 1600x1200x32, first without antialising and anisotropic filtering, and then configuring antialising at 4x and anisotropic filtering also at 4x. This improves the video quality but lowers the performance. We were willing to see how much performance we lost by putting the VGA to run at the maximum possible image quality. It is important to note that ATI chips can run at 6x antialising. Since NVIDIA chips cannot run at this configuration, we had to use 4x antialising to use a configuration that is valid to all video cards included in our benchmark, allowing direct comparison between them.

The results you check below. Keep in mind that models marked as “OC” are factory-overclocked. GeForce 7900 GT OC from XFX was running at 550 MHz with its memory being accessed at 1.63 GHz (815 MHz DDR) while the standard clock configuration for a GeForce 7900 GT is 450 MHz/1.32 GHz (660 MHz DDR). GeForce 7950 GX2 OC from XFX was running at 570 MHz with its memory being accessed at 1.55 GHz (775 MHz DDR) while the standard clock configuration for a GeForce 7950 GX2 is 500 MHz/1.2 GHz (600 MHz DDR).
