At default benchmark settings of 1024x768, 4AF, the 7800GTX's overall score
was 16,013 3DMarks. Increasing the resolution to 1600x1200 with no antialiasing
(AA) or anisotropic filtering (AF) the overall was 10,618. Still a hit of about
34%. Adding AA and AF to the 1600x1200 resolution dropped the results to 6785
3DMarks dropped the results another 34%.
As expected the NVIDIA 7800GTX maintained good performance with consistent
scaling with high resolutions and application of AA and AF. CPU remained
consistent through both tests rendered. Ragtroll test severely stressed the
video card, as normal, when application AA/AF at high resolution and AA/AF was
applied.
Application of sound dropped performance about 12% at each setting tested
compared with the sound off.
For the EVGA 6800 GT SLI tests the results at 1024x768, 4AF, the score was
19,198 3DMarks. A little better than 3K over the 7800GTX's score. At 1600x1200
with no AA or AF applied the SLI setup scored 12,906, a reduction of 33%
mimicking the 7800GTX's performance drop when upping the resolution. With
4xAA/16AF applied the score dropped a whopping 44% to 7,251 but still bettering
the 7800GTX's overall score by a 6% margin.
