The Nvidia GeForce 8800 GTX is in the lead on the Pier map, increasing the gap at higher resolutions. That’s a result you could expect considering that it has more TMUs and a more efficient TMU architecture, and a higher memory bandwidth as well. However, each version of GeForce 8800 GT and the GeForce 8800 GTS 320MB all make the game playable at any resolution. The same goes for the ATI Radeon HD 2900 XT 512MB. Although its average performance is much lower than that of Nvidia’s solutions, it is never lower than 60fps even at 1920x1200.
The Research map puts forth different requirements and the higher frequency of the shader domain allows the Nvidia GeForce 8800 GT to compete with the GeForce 8800 GTX at resolutions up to 1600x1200 and 1680x1050 inclusive. The flagship product wins at 1920x1200 but its advantage over the MSI NX8800GT OC amounts to 13% only. Every graphics card allows playing the game comfortably at 1920x1200.
It’s different when we use HDR but disable FSAA: the overclocked versions of GeForce 8800 GT are as fast as the GeForce 8800 GTX in both open and closed scenes. The reference version isn’t much slower and only at high resolutions. This must be due to the less strict memory bandwidth requirements in this test mode.
