Running Video Cards in Parallel

Posted by michael on from the seeing-double dept.

G.A. Wells writes "Ars Technica has the scoop on a new, Alienware-developed graphics subsystem called Video Array that will let users run two PCI-Express graphics cards in parallel on special motherboards. The motherboard component was apparently developed in cooperation with Intel. Now if I could only win the lottery."

    All you really need is some way to copy the data in memory from one card to another.

    Easy solution? Several high-speed serial connections in parallel between the two cards. With a little bit of circuitry on the card dedicated to keeping the data identical.

    Or, with a little bit of a performance hit, you could keep each section of RAM separate, and route misses over the cables.
