LuxMark is a OpenCL benchmark tool. The idea for the program was conceived in 2009 by Jean-Francois ‘Jromang’ Romang. The idea was quite simple, wrap SLG inside an easy to use graphical user interface and use it as a benchmark for OpenCL. From LuxRender.net.
Inno3D has done something special here, not only dominating the AMD range, but both the reference GTX 980Ti and Titan X by some margin.
