We don't have many details about the new card but we know it is based on the RV560 chip. The RV560 is nothing much more than the UMC chip - an 80 nanometre semiconductor with twelve pipelines. It will still be limited with the 128-bit memory interface but will end up faster than all X1600 XT based RV530 and the new X1650PRO based on the RV535 shrink.
The RV560 card will be branded as X1650XT. The launch is scheduled for September, together with the RV570-based new Radeon X1950 generation card, again one promising lower-end card.
This will give ATI some fuel to fight Nvidia's very successful Geforce 7600GS/GT series but we are sure that Nvidia has some magic backed up in its silky sleeve. µ
