PC enthusiasts and professionals are constantly searching for ways to increase the performance of their PCs. Scalability—using multiple graphics processing units (GPUs) in a single system with output to a single monitor—is one approach to maximizing graphics and system performance. But, in the past, adding additional GPUs didn’t always achieve the desired performance increase. Two PCI graphics cards in one system, two GPUs on a single card, even multiple cards in a workstation rack configuration all had serious limitations.
Now, NVIDIA unveils a revolutionary approach to combining multiple GPUs in a single system to scale performance. NVIDIA® SLI™ (Scalable Link Interface) multi-GPU technology takes advantage of the increased bandwidth of the PCI Express™ bus architecture, and features intelligent hardware and software solutions that allow multiple GPUs to efficiently work together to deliver earth-shattering performance.
How it Works :
Bus
bandwidth and system communication:
NVIDIA SLI technology fully exploits the increased bandwidth
provided by the latest bus architecture—PCI Express—when
communicating between the GPUs and the CPU. Providing
60x the bandwidth of PCI, the PCI Express interface
eliminates the bottlenecks caused by previous bus architectures
and allows for maximum system performance in a multi-GPU
configuration. |
GPU
communication: Featuring an intelligent communication protocol embedded
in the GPU, and a high-speed digital interface, NVIDIA
SLI-based GPUs can easily communicate with one another
without the overhead associated with a bus-only implementation.
In addition, unique software algorithms efficiently
share the workload to deliver unbelievable performance.

Image
Quality: Advanced compositing, rendering, and scanout technology
delivers uncompromised image quality, eliminating the
“flashing” effect found in previous solutions.
NVIDIA SLI multi-GPU technology also supports both analog
and digital output. |
