If you ask NVIDIA what SLI is it would go something like this: NVIDIA SLI (Scalable Link Interface) NVIDIA SLITM (Scalable Link Interface) technology is a revolutionary approach to scalability and increased performance. NVIDIA SLI takes advantage of the increased bandwidth of the PCI ExpressTM bus architecture, and features hardware and software innovations within NVIDIA GPUs (graphics processing units) and NVIDIA nForce4 MCPs (media and communications processors). Together the NVIDIA SLI patent-pending technologies work seamlessly to deliver heart-pounding PC performance. And depending on the application, NVIDIA SLI can deliver as much as 2x the performance of a single GPU configuration for unparalleled gaming experiences. So, what is it you still ask? Well so did Dave Kurns of Algonquin, IL so here it is. SLI is simply the use of 2 video cards in a PC that are bridged together (via an actual bridge piece put between the 2 cards, or via software as we are starting to see with newer versions) that harnesses the power of the GPU's on both cards to greatly enhance the performance compare to a single card. The question really is, do you need this technology. If you are a gamer, then it is probably something to look into. If you are the average PC user with very little high demand application needs than you more than likely do not. High intensity graphics rendering applications, video mixing and editing software, and soon to come 64 bit software applications will benefit from this type of technology. If you decide to pursue SLI or Crossfire (same type of deal just developed by ATI) you need to make sure you PC is equipped to handle it. Mainly the motherboard needs to be an SLI board, and more specifically, needs to be multiplier compliant with the set-up you want to use, such as 1x, 8x, 16x... You also need 2 of the same cards. Mixing and matching, at least as of now, doesn't work. You will also need the bridge or the software to run the cards in SLI mode,. Finally, you need to make sure your power supply can manage the power requirements. this could possible mean (2) 6 pin connectors if the cards require and external power source and if not, at least 25 amps on the 12 volt rail at a minimum. We hope this helps in your pursuit of SLI. if you have any further questions, feel free to call On-Site at 1-888-725-4509. |
