NVIDIA SLI Technology
NVIDIA SLI (Scalable Link Interface) technology allows users to install and benefit from two PCI
Express (PCIe) graphics boards in a single PC. Just as dual processors or dual core CPUs
improve compute performance, SLI allows dual GPUs (Graphics Processing Units) to significantly
accelerate graphics performance. Professional users benefit by using SLI technology on dual
NVIDIA Quadro GPUs to span an OpenGL window across multiple displays, or to run a single
application per GPU. Additionally, the SLI connector offers dual GPU performance on a single
display by leveraging the capabilities of two NVIDIA Quadro GPUs.
SLI for NVIDIA Quadro – Definitions
SLI Frame Rendering: Combines two PCI Express graphics boards with an SLI connector to
transparently scale application performance on a single display by presenting them as a single
graphics card to the operating system.
- Visual simulation, broadcast, and video applications that are fill rate-limited will benefit from
using the split frame rendering (SFR) mode.
- SPECviewperf® and other applications that are geometry-limited will benefit from using the
alternate frame rendering (AFR) mode.
- Two identical NVIDIA Quadro FX boards (4400, 3400, 1400)
- SLI connector
SLI Multi View: Combines the power of two NVIDIA Quadro PCI Express graphics boards to span
a single hardware-accelerated OpenGL application window across multiple displays, run a single
application per GPU with multiple display outputs, or enable other flexible usage of two PCI
Express graphics boards.
- View professional applications over multiple displays to increase visual real estate.
- Run a single application per GPU to offload geometry processing to a second GPU.
