Computex : chipset RD790 and quad-crossfire Posted on 07/06/2007 at 22:07 by Marc
The RD790 chipset, presented under NDA at CeBIT, is now publicly exhibited at Taiwan. This chipset will support two X16 or four X8 PCI Express slots and new standards such as PCI Express 2.0 and Hyper Transport 3.0.

Some manufacturers like ECS have chosen the two 16X slots instead of the four PCI Express 8x but with a third PCI Express graphic slot in 4X. Considering that the Quad-Crossfire and Quad-SLI aren't that interesting (AMD hasn't released such a solution yet and Nvidia's doesn't work despite being in shops), having two graphic cards seems to be the reasonable maximum. In the case of an additional card for physics effects (which we suspect could not happen), a 4X slot should be more than enough.
