NVIDIA GeForce GTX 680 "Kepler" On Linux
To kick things off on the Linux OpenGL side, the first test run is Unigine Heaven 3.0 at 1920 x 1080.
The Radeon HD 7950 was very competitive with the GeForce GTX 680. The Radeon HD 7950 at its reference speeds was at nearly the same performance level as the GTX 680, while overclocking the Radeon HD 7950 to its max led the Southern Islands GPU to take a definite lead. It is a pity that the NVIDIA Fermi/Kepler hardware cannot be overclocked under Linux at this time.
The Radeon HD 7950 and NVIDIA GeForce GTX 680 were tied when it came to power efficiency.
At the reference speeds for the HD 7950, the high-end NVIDIA and AMD graphics cards were both causing the system to go through around 300 Watts.
The Radeon HD 7950 did operate around 10°C cooler than the GeForce GTX 680.
