less sps at higher clocks seem to be faster than more sps at lower clocks... so this would make sense, especially if you factor in that mem bw isnt infinitive...

so what, after amd doing 40nm right, they somehow "forgot" how to design a chip for that node?
this doesnt make any sense whatsoever... wth is going on at amd???
1920 was likely for the 32nm Ibiza card. On 40nm that number would have pushed the HD 6970 well beyond the 300W mark if AMD had any hope of retaining nominal clock speeds.
