Benchmark: LuxMark 2.0
 |
LuxMark is an open-source, cross-platform GPU computing benchmark. Based on LuxRender, a freeware rendering program, this GPGPU benchmark tests each graphics card's ability to construct a complex scene using OpenCL.
The performance available from GeForce and Radeon graphics cards can vary wildly between games, and the same is true in other computing scenarios. We've added the increasingly-popular LuxMark benchmark to our suite to compare the GPGPU capabilities of each graphics card, and the Radeons are clear winners in this regard.
NVIDIA Kepler-derived cards make hard work of this OpenCL-based test. A Radeon HD 7870 is up to 3x as fast as the GeForce GTX 660 Ti.
