Performance in Synthetic Benchmarks
Some overclockers use the overall 3DMark score as the point of reference although it has little to do with a graphics card’s performance in real-life conditions. Here, the overall scores suggest that the Nvidia GeForce 8800 GTX is inferior not only to the pre-overclocked versions of the GeForce 8800 GT but also to the reference version but it is not so as we know from the gaming tests. So, let’s consider the results of the individual 3DMark tests we got when benchmarking the cards with anisotropic filtering and full-screen antialiasing.
The first test shows that the reference GeForce 8800 GT is no faster than the GeForce 8800 GTX, especially at high resolutions. This is a prerogative of the pre-overclocked versions from MSI and Leadtek. The ATI Radeon HD 2900 XT 512MB performs poorly in this test, contrary to its overall score.
The MSI card is ahead of the GeForce 8800 GTX in the second test at 1280x1024 only. At other resolutions the gap is less than 1fps due to the weaker memory subsystem of the new card. The AMD/ATI card feels more confident than in the previous test, yet it is still far behind even the reference GeForce 8800 GT.
The third test agrees that it’s only at overclocked frequencies that the GeForce 8800 GT can outperform the GeForce 8800 GTX. However, it is only 2% behind the flagship of the GeForce 8800 series at 1280x1024 and 5-6% behind it at 1920x1200.
