NVIDIA GeForce GTX 680 "Kepler" On Linux

Lastly, here is a look at the Unigine Heaven 3.0 performance for the Radeon HD 7950 (900/1375MHz) and GeForce GTX 680 when scaling at all major resolution steps between 800 x 600 and 2560 x 1600.

In looking at the overall system power consumption for the selection of graphics cards for these OpenCL/OpenGL tests and other Linux OpenGL benchmarks, the NVIDIA GeForce GTX 680 had an average core temperature of 72°C. Meanwhile, the AMD Radeon HD 7950 at its stock speeds averaged out to 63°C.

When looking at the overall system power consumption for the plethora of Linux benchmarks, the average system power consumption for the AMD FX-8150 system with the NVIDIA GeForce GTX 680 was 258 Watts while the average with the AMD Radeon HD 7950 installed and at stock speeds was 248 Watts, but that's not a huge difference and the power efficiency between the two competing graphics cards ended up being similar.
