The newer Radeon HD 5770 design means that it's far more power-efficient than the GTX 260. We noted that the MSI HAWK shipped with a higher core voltage than a regular HD 5770, and that's manifested by a 15W increase in the under-load power-draw.

The increased core voltage also means that the cooler has to work harder to keep temperatures in check. The under-load temperature is obtained by using the default fan-speed profile that translates to around 1,500rpm at full load. The HAWK is quieter than either the reference HD 5770 or GeForce GTX 260 OC, too.
We manually set the fans to spin at 2,500rpm - emitting the same noise as the Sapphire HD 5770 reference - and under-load temps fell to 67°C. One would need to ratchet them up to the ear-splitting 4,800rpm (100 per cent) if MSI's claims of '13°C improvement over stock' are to be believed.
