The results of the third test generally repeat those of the second one, with Leadtek’s SLI kit on top, because these two tests differ in the plot but are technologically very much like each other.

Again like in the second test, Leadtek’s SLI system is the best in the lowest resolution, but then come abreast to the GeForce 6800 Ultra.

The speed of the fourth game test depends mostly on the speed of execution of version 2.0 pixel shaders. Clocked at 500MHz each, the two graphics processors from the Leadtek kit deliver the performance of an ATI RADEON X850 XT Platinum Edition. Moreover, overclocking them to 545MHz makes the Leadtek SLI kit the winner in this test. The performance gain from overclocking is 5-8%.

Like in the two previous tests, the Leadtek kit is a leader in 1024x768, but loses its first place to ATI’s cards which are equipped with the most advanced memory controller for today. So, the high overall 3DMark03 score of the Leadtek WinFast PX6600 GT TDH SLI is only correct in the “pure speed” mode. With enabled full-screen anti-aliasing and anisotropic filtering, however, the SLI platform performs much like a GeForce 6800 Ultra or a RADEON X850 XT Platinum Edition.
