Overclocking X700 XT - Doom 3 Performance

Here we'll look at Doom 3, which, seeing that it is fairly graphics intensive, should be one to benefit from any increased clock speeds.

 

X700 XT - Doom3 (FPS) 640x480 800x600 1024x768 1280x1024 1600x1200
Default (475/525) 94.7 85.5 63.8 43.8 30.7
Overdrive (479/525) 94.8 84.9 64.0 44.2 31.0
525/560 96.6 90.4 69.5 47.9 33.8
 
% Increase from Default 640x480 800x600 1024x768 1280x1024 1600x1200
Overdrive (479/525) 0.1% -0.7% 0.3% 0.9% 1.0%
525/560 2.0% 5.7% 8.9% 9.4% 10.1%

The performance gain with OverDrive on the XT manages to hit the lofty heights of a whole 1% performance gain, whilst the overclocked settings gives a little over 10% greater performance at high resolution.

 

 

X700 XT - Doom3, 4x FSAA + 8x AF (FPS) 640x480 800x600 1024x768 1280x1024 1600x1200
Default (475/525) 65.2 50.4 38.9 27.0 15.4
Overdrive (479/525) 65.7 50.7 39.2 27.2 15.6
525/560 70.9 54.8 42.4 29.6 16.6
 
% Increase from Default 640x480 800x600 1024x768 1280x1024 1600x1200
Overdrive (479/525) 0.8% 0.6% 0.8% 0.7% 1.3%
525/560 8.7% 8.7% 9.0% 9.6% 7.8%

Overdrive here, again, yields a high performance gain of a little over 1%, whilst the overclocked settings are giving about 10% extra at best - this pushes the average FPS a little closer to 30 at 1280*1024.
