R480 to come in the fourth quarter
 

ATI'S NEXT FASTEST graphic thing will be based on 0.11µ (micron) architecture. This is the natural direction for ATI to migrate from 0.13µ low K marchitecture to pure 0.11µ without low K. When you make things smaller you can possibly clock a chip even higher, but we don't have any idea what frequency ATI is aiming for. That's exactly where its R480 chip is at this time.
