AMD will reportedly release three more graphics cards for the mainstream and value market segments in September. Hexus.net has published the first pictures of the new ATI RV730 XT, ATI RV730 Pro and ATI RV710 (engineering samples), which are expected to appear on the market next month, following the recently released mid-range and high-end ATI Radeon HD 4850, 4870 and its dual-GPU X2 derivatives.

The RV710 3D graphics accelerator will be part of a passively cooled Radeon HD 4450 and Radeon HD 4470 models, while the RV730 Pro and the faster RV730 XT chips are expected to arrive as the Radeon HD 4650 and HD 4670.
