The Inq has a new round of rumors (or is it rumours?) regarding the next generation ATi part, the R580.

"We finally confirmed that ATI's upcoming R580 GPU will again have sixteen pipelines only but this time it will have 48 Pixel Shader units. What does that mean? Well, it's not the easiest subject to explain, but pipelines in this case can be associated with a job done by texture memory units."
