RD790 to gain triple and quad CrossFire capabilities

AMD is preparing to update its aging 580X chipset later this year with the upcoming RD790. The upcoming RD790 serves double duty as the single and dual processor platform of choice for AMD desktop products. RD790 introduces 41 PCIe 2.0 lanes to AMD’s Socket AM2+ platform for Stars-family processors.

Motherboard manufacturers can distribute the PCIe lanes in many configurations, including four PCIe 2.0 x16 slots with eight-lane signaling. With all 41 PCIe 2.0 lanes, the RD790 chipset has a TDP up to 10-watts. AMD roadmaps reveal the multiple PCIe 2.0 slots are used for an improved CrossFire multi-GPU technology. The improved CrossFire multi-GPU technology supports up to four ATI Radeon HD 2900 XT graphics cards in Quad CrossFire configurations.

Unlike NVIDIA’s SLI, which supports dual or quad graphics cards in SLI, the improved CrossFire solution can take on three cards for improved performance. AMD claims CrossFire scaling with three cards yields a 2.6x performance increase. Two cards in CrossFire yield a 1.8x performance improvement. AMD roadmaps do not divulge how well CrossFire scales with four GPUs.

Expect RD790 to arrive later this year in time for the AMD Phenom product launch in single and dual processor configurations.

This didn't work well for Nvidia, and it won't work for ATI either. There are not many people out there dumb enough to blow their money on 3 or 4 video cards. Would I like to have a 4 card setup? Sure, maybe if it was free. Do I need 4 cards or even 2 cards for my games to look great? Nope. 1280x1024 is enough for me, and my single 8800 can handle that just fine.

I'm also kind of wondering why they're bothering with this. I guess probably to at least be able to say they have the capability, but it just kind of makes them look pathetic since Nvidia already pioneered this market over a year ago.

I wouldn't even use it if it came for free

too much heat, too much noise, too much electricity

gimme the cards and i'll sell at least 2, prolly 3.
