Even though this is an old game, its importance comes from the fact its engine is used by several other games, like Jedi Knight II and Medal of Honor, and also because this game is very sensitive to any changes on the hardware configuration.

We used the demo four available on version 1.32 of Quake III and wrote down the obtained number of frames per second to make our benchmarking with this game. We ran this demo three times at 1024x768x32 resolution and all image quality settings on their default configuration and we picked the middle value for our comparisons, i.e. we discarded the highest and the lowest values.

Check the results below.

Processor	Frames Per Second	Difference
Sempron 3000+ (1.8 GHz)	244.9
Celeron D 331 (2.66 GHz)	162.7	50.52%

On Quake III, Sempron 3000+ was 50.52% faster than Celeron D 331, showing that the AMD CPU is a better choice if you like gaming.
