AMD could have a monster midrange card on the horizon. According to sources, RV740 may be a 40nm process shrink of RV770LE - the currently available HD 4830. Sources received information claiming that RV740 will have 640 stream processors, 32 texture units and 16 render back-ends, just like the HD4830. On the memory side, things have changed. The memory is expected to be 900MHz GDDR5 (3600MHz effective) for the highest-end card using the RV740 GPU, utilizing a 128-bit memory interface. (source: vr-zone.com)
