Call of Duty

Here we'll look at the performance of GeForce 6800 Ultra under this Quake3 engine based title.

CoD (FPS) 640x480 800x600 1024x768 1280x1024 1600x1200
6800 Ultra 126.1 122.4 123.1 123.3 120.3
5950 Ultra 124.1 126.8 127.3 122.5 112.9
5900 Ultra 126.5 125.3 124.0 123.5 107.7
5800 Ultra 125.2 127.1 126.6 123.9 110.4
6800 Ultra % Difference 640x480 800x600 1024x768 1280x1024 1600x1200
5950 Ultra 1.6% -3.5% -3.3% 0.7% 6.6%
5900 Ultra -0.3% -2.3% -0.7% -0.2% 11.7%
5800 Ultra 0.7% -3.7% -2.8% -0.5% 9.0%

As we've seen in a number of games benchmarks, Call of Duty is nearly completely CPU bound under normal rendering. The 5950 only shows some fill-rate limitations above 1280x1024, hence only a small, 6.6%, performance gap opens up between the higher performance 6800 Ultra an the 5950.

CoD - 4X FSAA + 8X AF (FPS) 640x480 800x600 1024x768 1280x1024 1600x1200
6800 Ultra 123.4 123.2 124.4 113.8 104.9
5950 Ultra 121.0 117.1 103.2 84.1 66.2
5900 Ultra 120.2 114.8 100.9 81.2 63.6
5800 Ultra 124.2 120.4 104.9 79.5 54.2
6800 Ultra % Difference 640x480 800x600 1024x768 1280x1024 1600x1200
5950 Ultra 2.0% 5.2% 20.5% 35.3% 58.5%
5900 Ultra 2.7% 7.3% 23.3% 40.1% 64.9%
5800 Ultra -0.6% 2.3% 18.6% 43.1% 93.5%

With the higher image quality settings of 4X FSAA and 8X AF enabled we can see that the 6800 Ultra and the 5950 are beginning to show some fill-rate limitations, although the 6800 Ultra isn't showing anything near the performance drop of the 5950. The performance difference between the 6800 Ultra and 5950 increases to a maximum of about 59%.

6800 Ultra (FPS) 640x480 800x600 1024x768 1280x1024 1600x1200
Normal 126.1 122.4 123.1 123.3 120.3
8X AF 125.4 127.1 123.1 120.5 113.7
4X FSAA 125.4 124.2 125.3 124.4 114.9
4X FSAA + 8X AF 123.4 123.2 124.4 113.8 104.9
% Diff from Normal 640x480 800x600 1024x768 1280x1024 1600x1200
8X AF -0.6% 3.8% 0.0% -2.3% -5.5%
4X FSAA -0.6% 1.5% 1.8% 0.9% -4.5%
4X FSAA + 8X AF -2.1% 0.7% 1.1% -7.7% -12.8%

With the various settings enabled we can see just how CPU limited the 680 Ultra is in this test. In all cases the average rendering performance is above 100 FPS and even with both 4X FSAA and 8X AF enabled there is only a 13% performance drop.
