This is AMD’s plan. They killed the ATI brand as they want to move towards Fusion, CPU meats the GPU design, but as you can see Radeon sticks for discrete graphics of the future.
The new Radeon HD 6000 is a tweak to an existing architecture that will squeeze better performance per watt, better performance overall and some new things like UVD 3.0 that will make better use of six Display ports and make it more affordable to actually use such a setup.
Naturally decoding and encoding will get faster and better, but it was already quite good. The chip is an evolution rather than a revolution and the real revolution comes in 28nm, at some point in 2011 and no, the revolution will not be televised.
We've already have reported that the new cards should start showing up as of October, with a dual-GPU card comming before the end of the year and the first leaked benchmarks are showing that the Radeon HD 6000 has a lot of potential.
