The GTX 980 and GTX 970 do not bring a huge performance boost compared to the previous generation, but they proves Maxwell is vastly more efficient than Kepler. The GTX 980 has a TDP of just 165W and GTX 970 has a TDP of just 145W. For comparison, the mid-range R9 270X has a TDP of 180W, while AMD’s latest R9 285 needs 190W of power. The old Tahiti-based R9 280 has a TDP of 200W, while the 280X churns out 250W, just like the GTX 780 Ti.
EVGA GTX 970 SC ACX 2.0 consumes a little bit more compared to reference design due the factory overclock.
