Each of the three game tests generates an average frame-rate (frames rendered per second measurement) that is used to calculate the overall 3DMark score. The formula for calculating the overall 3DMark05 score is:
3DMark05 score = (Game Test 1 * Game Test 2 * Game Test 3)^0.33 * 250
This formula generates a geometric mean, weighting the game tests equally on the total score. Even though one game test may be heavier (run slower) than another test, both of these affect the total score equally.

The overall scores of 3DMark05 tell us that NVIDIA has grabbed the lead in terms of performance in future games. Even though the results of graphics processors with 16 pixel pipelines and 6 vertex processors are close, NVIDIA’s GeForce 6800 Ultra pulls a bit ahead in all resolutions.
ATI’s RADEON X800 PRO is about 350 marks behind its direct rival GeForce 6800 GT and is 800 marks behind the RADEON X800 XT Platinum Edition in default benchmark run. Probably everyone is capable of figuring out whether this is important or not, but the fact that the X800 PRO has, at least, surpassed 4000 marks milestone.
The GeForce 6800 is far behind more expensive options and finds itself on the same line with far more affordable GeForce 6600 GT.
RADEON 9800 XT is the king of the previous-generation graphics cards, still it cannot keep up with the current mainstream offerings, which is a sing of unbelievable progress.
