Performance in Synthetic Benchmarks
The Nvidia GeForce 8800 GT scores only 328 points more than the ATI Radeon HD 2900 Pro in 3DMark05. The pre-overclocked version from Leadtek increases the gap by 362 points more. 3DMark05 defaults to the resolution of 1024x768, so these numbers are not reflective of the new card’s real performance. The overall scores suggest that the new card is better than the GeForce 8800 GTX, yet we know that it’s not true from the gaming tests. So, let’s better see what we have in the individual tests.
The results of the first test are logical since the GeForce 8800 GT is better than the GeForce 8800 GTS 320MB in every parameter including the frequency of the main domain and the number of TMUs. The speed of the shader processors is not crucial in this test and the effect from overclocking can only be observed at high resolutions.
The second test puts a stress on math1ematical computations and the Leadtek WinFast PX8800 GT Extreme is everywhere ahead of the reference card. The Nvidia solution is also ahead of the Radeon HD 2900 XT/Pro that has 320 ALUs, although the gap is smaller here.
The Nvidia GeForce 8800 GT and its overclocked version from Leadtek are also superior in the third test. This resembles the first test except that ATI’s Radeon HD 2900 are not so far behind the leader.
