Several sites on the net are reporting that Nvidia's PCI-Express version of the 6800 Ultra video card would have an SLI feature built-in.
Quote from HardOCP:
“SLI (Scan Line Interleaving) created by 3dfx six years ago was all about pure performance and higher resolutions. Back in those days whoever had the fastest graphics solution won. The idea was that if you could add multiple 3D accelerators in one system you could speed up 3D rendering on that PC. 3dfx conquered this challenge by creating SLI or Scan Line Interleaving technology. SLI technology from 3dfx worked by having one card render the even number of lines on the screen while the other card worked on the odd number of lines. This basically “doubled” frame rate performance and allowed resolutions up to 1024×768.”
Quote from The TechReport:
“Today, NVIDIA is announcing is new SLI technology for GeForce 6800 graphics cards with PCI Express. Those “golden fingers” protruding from the top of the GeForce 6800GT are, in fact, an SLI connector. Place a pair of GeForce 6800GT (or pick your flavor, including GeForce 6800 Ultra) cards into a special motherboard with a pair of PCI Express X16 expansion slots, and this connector will help hook the two cards together for tandem operation. Like its predecessor, the new SLI will accelerate graphics and games on a single monitor using two graphics cards. For real. ”
