In the power consumption side, the HD 6970 has a TDP less than 300W. Actually the HD 6970 will have three levels of power consumption controlled by a new feature called PowerTune:
– Maximum Power
– Typical Gaming Power
– Typical Idle Power

Humm… Typical gaming power I see but maximum power? For FurMark-like apps?
