AMD Radeon R7 260X, R9 270X, and R9 280X Tested
Power Consumption and Noise

Under both idle and load conditions, the new Radeon R9 and R7 series cards all consumed somewhat less power than their closest Radeon HD 7000-series based counterparts, though the differences weren't dramatic. Considering how similar the cards are, it should come as no surprise that power consumption is similar as well.
The noise output from the new Radeon R9 and R7 series cards, however, is a different story. All three of the cards we tested were clearly quieter than the previous generation. The XFX Radeon R9 280X we tested was much quieter than the reference Radeon HD 7970, and the R9 270X and R7 260X were quieter than 7870 and 7790, respectively, as well.
