This dynamic clocking rumor is very interesting. I hope it's sophisticated. I could imagine the TDP budget being shifted around on the GPU as needed. Highly utilized units are clocked higher while waiting/idle units are clocked lower. This would increase power consumption on average but would stay within the TDP. I hope one can deactivate it for older games though. Or when you are CPU bound or have vsync enabled that it doesn't kick in when the chip doesn't run at full capacity.
