Neoseeker has posted a Preview of ATI's Crossfire multi VPU solution.
Crossfire is implemented differently than SLI, and brings to the table a few
interesting things that ATI feels will differentiate their product from SLI
enough to capture the hearts of enthusiasts. Here's a quick quote:
Supertiling is exclusive to ATI's CrossFire and NVIDIA does not have an
equivalent mode with SLI. With Supertiling the screen is divided up into
32x32 pixels squares like a chess board and the two cards render alternate
tiles. ATI's explanation is that the work load is more efficiently divided
up with the supertiling method as complex objects are more evenly split
between the two cards. The example shown in ATI's documents is a pair of
urns - note that neither card renders significantly more geometry than the
other. ATI claims that supertiling works on virtually every D3D
application.
