SLI technology does not work in this test. The Leadtek multi-GPU kit is slower than the single card.

NVIDIA’s SLI not just works in Aquamark , but is highly efficient: the Leadtek WinFast PX6600 GT TDH SLI kit goes abreast to the RADEON X850 XT Platinum Edition. This test is free from complex shaders, so our overclocking the SLI platform yields almost no perceptible gain.

Up to 1600x1200 resolution the SLI kit from Leadtek performs just like the RADEON X850 XT, but the small amount of memory and the narrow 128-bit memory buses restrain its performance in the highest display mode. And still, even in this case the Leadtek kit successfully competes with the RADEON X800 XL that is equipped with a more advanced memory controller.
