SLI Frame Rendering Print
June 2011
Combines two Quadro graphics boards with an SLI connector to transparently scale application performance on a single display by presenting them as a single graphics card to the operating system.

If you are running two cards in SLI, you can choose to either use Split Frame Rendering (SFR) or Alternate Frame Rendering (AFR).

SLI for Quadro cards. Two (2) modes:
Split Frame rendering (SPR)
    • Fill rate limited applications frequently found in visual simulation

In SFR, every frame is split horizontally into two portions. Each portion is processed by one GPU and the final frame is sent to the framebuffer. The actual division of the frame is dynamically adjusted according to the load of the two GPUs and the complexity of the frame.

Alternate Frame rendering (AFR)
    • Geometry limited applications in CAD and DCC

In AFR, each frame is exclusively and sequentially processed by alternating GPUs. For example, GPU 1 will process Frame 1 while GPU 2 will process Frame 2. Once Frame 1 is completed and sent to the framebuffer, GPU 1 starts processing Frame 3. GPU 2 will finish processing Frame 2 and start on Frame 4. This goes on with each GPU processing different, alternating frames.
