XFX Radeon HD 7950 Black Edition Overclocked 3GB Graphics Card Review

To test power consumption, we monitor the overall power of the system through a plug-in electricity usage monitor at an idle and load state. This allows us to show the fluctuation between how much power draw the graphics card takes at idle and at load. By monitoring the overall usage of the whole system, it gives an easy comparison if you wish to do the same yourself as opposed to buying very expensive individual testing equipment.

Whereas the 7970 runs at under 100w idle, we did not that the 7950 run slightly higher, however under full load conditions, its power consumption was around 15w lower than its bigger brother;  similar performance with less power.
