OctaneBench allows you to benchmark your CUDA capable GPU using Octane Render code. However, when dual D700s are rendering OpenCL, they, of course, beat the TITAN X. The single GeForce TITAN X beats the single FirePro D700. (LARGER number means FASTER in Thousands of Samples per Second.) For this round we used the default Sala scene (488K Triangles) and rendered using all available GPUs, but GPUs only. LuxMark 2.1 is an OpenCL benchmark that renders scenes of various complexity.
