Performance in Synthetic Benchmarks

Futuremark 3DMark 03

Quite expectedly SLI technology is perfectly compatible with the benchmarks from Futuremark, and the results are another testimony to its efficiency: the SLI platform overcame the next landmark, a total score of 20,000 points. The GeForce 6600 GT pair also did excellently, outperforming the single GeForce 6800 Ultra.

The first test is simple, so we can’t expect a big effect from enabled SLI, but it is present, especially in high resolutions. The pair of two GeForce 6600 GT cards profits the most from SLI, achieving a performance gain of 30-35 percent. The GeForce 6800 Ultra SLI configuration is 15-20 percent faster than the single card. The multi-GPU mode helps NVIDIA’s GPUs to outperform their rivals from ATI Technologies.

The advantages of NVIDIA SLI technology are more conspicuous in the “eye candy” mode – the performance gain is about 75 percent for the GeForce 6800 Ultra SLI in 1600x1200 resolution, and about 100 percent for the GeForce 6600 GT SLI!
