NVIDIA SLI Dual Graphics Technology

With NVIDIA SLI (Scalable Link Interface) dual-graphics technology, an optional second PCI Express graphics card will significantly increase graphics performance on your computer. Benefits of this technology can be seen in the improved portrayal of the 3-D graphics used in gaming and design applications.

Each graphics card includes a GPU (graphics processing unit). The two GPUs dynamically share their workload to provide the best possible performance. For a given application, the SLI software selects the optimum rendering (processing) mode. The two most basic modes are split frame rendering and alternate frame rendering. In split frame rendering, the GPUs divide the work; each GPU renders part of every frame that displays. In the alternate frame rendering mode, each GPU alternately renders the full-screen image.

For more information, see the documentation that came with your graphics card.
