The idle consumption figures have the R9 290 Crossfire cards using a little more power than normal, though it’s hardly worth mentioning.
The R9 290 Crossfire power consumption wasn’t as horrible as we expected when testing BioShock Infinite with the GTX 970s using only 8% less power.
The GTX 970 SLI setup consumed 17% less power than the R9 290s when testing Metro: Last Light.
Finally, when comparing power consumption performance with Tomb Raider we find that the GTX 970 SLI cards pulled just 7% less power than the R9 290s.
