AMD Radeon HD 7950 3GB with PowerTune Boost Review
Power Consumption, Temperatures and Noise
Power consumption on the newly updated HD 7950 is a little bit higher–23 watts by my testing. That makes sense as the card should much more frequently be in its highest clock (and usage) state, and should hit its target peak power consumption accordingly.
Temperatures stay pretty much the same though sound levels are a bit higher since the fan will be required to dissipate more heat more often.
