RD790 to gain triple and quad CrossFire capabilities
AMD is preparing to update its
aging 580X chipset
later this year with the
. 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.

HPC Computing Platform?

I'm thinking maybe the RD790 Quad CrossFire will be targeted towards the high performance GPU computing market, similar to Nvidia's current Tesla platform.
The fact that Quad CrossFire and Tesla both support up to 4 GPUs is an interesting coincidence ...

The truth is that CrossFire is way more scalable than SLi, as the number of cards that can be in the chain is basically only limited by the amount of data that can travel across the pci-express bus. At least thats what ive read.

Tesla is for Mid to large scale business computation/servers. But still you could consider it a high performance GPU>
