Permite ligar duas placas gráficas NVIDIA para distribuição da carga de processamento gráfico entre as duas.

Segundo a definição da própria NVIDIA:
"Scalable Link Interface (SLI) is a multi-GPU configuration that offers increased rendering performance by dividing the workload across multiple GPUs. To take advantage of SLI, the system must use an SLI-certified motherboard. Such motherboards have multiple PCI-Express x16 slots and are specifically engineered for SLI configurations.
To create a multi-GPU SLI configuration, NVIDIA GPUs must be attached to at least two of these slots, and then these GPUs must be linked using external SLI bridge connectors. Once the hardware is configured for SLI, and the driver is properly installed for all the GPUs, SLI rendering must be enabled in the NVIDIA control panel. At this point, the driver can treat both GPUs as one logical device, and divide rendering workload automatically depending on the selected mode."
