Dual Core Intel Platform Shootout - NVIDIA nForce4 vs. Intel 955Xby Anand Lal Shimpi on April 14, 2005 1:01 PM EST

The final performance investigation of this review focuses exclusively on NVIDIA's nForce4 SLI Intel Edition. More specifically, it focuses on SLI performance. The performance benefits of SLI apply just as much to Intel as they do to AMD, but to give you an idea of those performance benefits, we ran tests in Doom 3, Half Life 2 and Splinter Cell: Chaos Theory - three of the most demanding games out today.
Doom 3 Performance
Doom 3 has always been a strong selling point for NVIDIA, and the performance impact of SLI here is extremely strong. At 1600 x 1200, the 6800GT gains 34% from SLI, while the 6600GT gets a nice 56% increase in performance. For Doom 3, a pair of 6600GTs are not only cheaper, but also 22% faster than a single ATI Radeon X850 XT Platinum Edition.
Turning on 4X AA results in even larger performance gains, with the 6800GT getting anywhere from a 23% up to a 70% increase in performance. The 6600GTs fall between 58% and 75%, all very impressive gains as you would expect from a doubling of the number of GPUs in the system.
