Fine HD

AMD has done 3 things to differentiate the 5570 from the 5670. The first of which is to significantly castrate the 5670’s memory bandwidth. While the 5670 had 1GHz (4GHz effective) GDD5, the 5570 drops that for simple 900MHz (1.8GHz effective) DDR3, giving the card only 45% of the memory bandwidth of the 5670. The second change is more customary, and that is lowering the core clock from 775MHz to 650MHz, leaving the card with roughly 83% of the computational/rendering/texturing performance of the 5670. None of the SIMDs have been disabled however, so this is a fully functional Redwood GPU.
