AMD Radeon HD 7970 3GB Graphics Card Review
Andy Ruffell / 13 years ago
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.
Measuring the whole system power draw, the new AMD ZeroCore technology really kicks in, with a whopping low 81.3 Watts. At load, we still see high results, but for a card that shows the type of performance that we’ve seen today, 251.1 Watts for the whole system draw, really is nothing.
