ASUS Matrix Radeon HD 7970 3GB Overclocked Graphics Card Review
Power Consumption, Temperatures and Noise
While power consumption is not realistically something that buyers of a card like this are going to put too much weight on, the ASUS Matrix card does okay with a only a modest increase in both idle and peak power consumption. Yes, the NVIDIA GeForce GTX 680 is a much more efficient GPU for the high end gamer if that is something you are concerned with.
Where ASUS DID improve with the Matrix HD 7970 is on the cooler - it comes in 10C lower than the reference card and 14C lower than the GTX 680 reference.
And to top it off, this very efficient cooler is also very quiet, taking a whopping 10 dBA off the sound levels of the reference cooler under a full load! That is a remarkable difference!
