NVIDIA SLI intelligently scales graphics performance by combining multiple GeForce GPUs on an SLI certified motherboard. With over 1,000 supported applications and used by over 94% of multi-GPU PCs on Steam, SLI is the technology of choice for gamers who demand the very best.
SLI features an intelligent communication protocol embedded in the GPU, a high-speed digital interface to facilitate data flow between the two graphics cards, and a complete software suite providing dynamic load balancing, advanced rendering, and compositing to ensure maximum compatibility and performance in today’s latest games.
Thanks to Fermi’s architectural innovations, SLI scaling is higher than ever. Across many popular titles, over 80%, and at times 100% performance improvement, can be obtained by adding a second GPU.
Beyond just better performance, SLI offers a host of advanced features. For PhysX games, SLI can assign the second GPU for physics computation, enabling stunning effects such as life-like fluids, particles, and destruction. For CUDA applications, a second GPU can be used for compute purposes such as Folding@home or video transcoding. Finally, for the ultimate in image quality, SLI antialiasing offers up to 64xAA with two GPUs, 96xAA with three GPUs, or 128xAA with four GPUs.
