Coming from the Register today.... "THE PCI SPECIAL Interest Group has happily ratified AMD's new RD790 core logic for implementation of, well, PCI and PCI Express. This, it would seem, clears the way for AMD to start shipping out the chipset to partners.
The 790 should put the aborted RD600 (which lost its way during the sale and was widely derided by both press and manufacturers) out of the minds of consumers, and regain some mindshare against nForce 6.
The gossip is that 790 will support HT 3.0 (that's HyperTransport, not HyperThreading, folks). The HT clock will scale up to 2.6GHz, as well as providing enough bandwidth for a stonking 42 lanes of PCI-Express 2.0 - that's enough for a couple of DAAMIT cards in CrossFire (supporting physics, obviously), a couple of x4 lanes and a stinky x1 lane that will never get used because no one makes any boards in that form factor."
