LuxMark 2.0: "Sala" Scene
The same pattern emerges, though this time, the GeForce GTX Titan pulls even further ahead of the GeForce GTX 680. We see further evidence that Kepler's underwhelming performance isn't a result of stacked benchmarks or a bad API, but rather the fact that Nvidia didn't prioritize compete, whereas AMD's GCN is much more adept in this discipline. In fact, Titan's OpenCL performance is still quite a bit under where it theoretically should be. Could it be that Nvidia simply isn't optimizing for OpenCL, instead putting its resources into CUDA?
