Testing NVIDIA SLI - Two Parts @ Digit-Life

"NVIDIA SLI operates differently. Like in the latest multi-chip solutions from 3dfx, the pair is formed by a Primary (Master) card and a Secondary (Slave) card. A special buffer is allocated in a master card to assemble the image. But we have written much about operating methods of multi-chip solutions, so we shall not repeat ourselves.

Note that there is a special unit inside the corresponding chips (NV45, NV43), which is responsible for SLI, working with shared resources of the two video cards. The data is exchanged via a bus and synched via a special SLI connector plugged to both cards."
I'm still pretty excited about nVidia SLI, it doesn't seem to be as flexible as 3DFX SLI but should still dominate the video card market.
