GeForce GTX 880M, 870M, And 860M: Mobile GPUs, Tested

Power And Heat

So far, the GeForce GTX 770M looks to be slightly faster than the 860M. And yet, it also uses less power. Other modules follow the power curves we'd expect, given their performance. I wouldn't be surprised to see the next generation of gaming notebooks including larger and heavier coolers to contend with the additional heat. 

Thermals aren't an issue for Origin PC’s full-sized Eon17-S, though. I didn’t need to adjust its fan speed at any point during our experimentation. Rather, the system sets its fans to roughly 50% under load, regardless of the graphics module you have installed. If, at some point in the future, you find your Eon17-S to be noisy, it’s probably time to blow the dust out.
