AMD and NVIDIA may focus their attention on mid-range graphics with new introductions this fall, based on early details divulged this morning. The Radeon HD 6000 series would start with just two models in the 6700 line; their names aren't known by DigiTimes, but they would be the Barts XT and Barts Pro hinted earlier and would be direct replacements for the 5750 and 5770. Both are rumored to get their unveiling in October.
