    Q4: What is Alternate Frame Rendering (AFR) technology?
    A4: ATI has developed a multiple chip parallel processing technique that works within MAXX implementation called Alternate Frame Rendering or AFR. In the AFR process, one chip renders even frames while the other chip renders odd frames. Each chip processes triangle setup for its own frame without waiting for the other chip making AFR the more efficient multiple chip processing technique.

    ATI SLI

    ATI's technology is superior to NVIDIA's SLI in several ways:

    While NVIDIA SLI splits the screen into two parts and one GPU renders each half, ATI's solution breaks the screen into little squares. Remember the chessboard effect you had when pipelines were bad with the softmod?
    That's how it is going to work, just on a bigger scale, called "Super Tiling". Any GPU from R300 and up supports Super Tiling in hardware and they can be mixed when in SLI mode.
    However, ATI most probably will not enable SLI for GPUs other than the R4xx and R520 series.

    ATI's SLI is also not limited to two video cards. There will be one master card which presents the rendered data to the screen and coordinates the slaves which transfer their rendered data into the master's framebuffer. A physical PCB to link the video cards is not required, everything is done via PCI-Express bus.
