San Jose (CA) - Nvidia's Scalable Link Interface (SLI) lets users integrate two GeForce 6800 PCI Express graphic cards in one PC. SLI itself is a concept which first was introduced by 3dfx back in 1996 with the Voodoo 2 SLI and Nvidia believes that its new concept can almost double the performance of one 6800.
Alienware recently announced its graphics array technology which allows using two graphics cards in an array with siginifacnt performance gains. With PCI Express moving into the market, Nvidia now has announced SLI as another option to increase the graphics capability of a PC.
Using two PCI Express GeForce 6800 graphic cards requires a dual x16 PCIe capable mainstream motherboard, supporting chipsets as well as a brigde connector to couple the cards. The gain in processing speed results from a concept that both cards render different sections of the screen. By using dynamic load-balancing, each card can be assigned a flexible section of the screen to be able to work at full capacity.
