LuxMark is a OpenCL benchmark tool. The idea for the program was conceived in 2009 by Jromang. It was intended as a promotional tool for LuxRender (to quote original Jromang's words: "LuxRender propaganda with OpenCL"). The idea was quite simple, wrap SLG inside an easy to use graphical user interface and use it as a benchmark for OpenCL. After Anandtech adoption of SLG as OpenCL benchmark, the code was finally written.

After a year from LuxMark v1.0 release, it has been widely used as OpenCL benchmark by AnandTech, Tom's Hardware, Vr-zone and other sites. AMD has used LuxMark as one of the 5 GPU computing benchmarks to present the new HD7970.

LuxMark v2.0 includes SLG2 as rendering engine with Metropolis Light Transport, Multiple Importance Sampling, Image reconstruction done on the GPU, support for multiple OpenCL platforms (i.e. Nvidia users can use Intel or AMD CPU device) and many more new features. The new features rise the complexity of the benchmark of nearly one order of magnitude and it should be able to put some serious stress on the new generation of GPUs. However, the capability to submit results to a centralise WEB database looks like the most interesting new feature of LuxMark v2.0:

  • Open source
  • 100% OpenCL
  • Cross platform (Linux, MacOS, Windows, etc.)
  • Complex/real world code used as GPU computing benchmark
  • Support for OpenCL GPUs-only, OpenCL CPUs+GPUs, OpenCL CPUs-only and native CPU-only benchmarking
  • Support for Interactive mode
  • Easy to run
  • Multiple scenes usable as benchmarks


Windows 32bit executables:

Windows 64bit executables: (you may have to download and install VisualStudio 2008 SP1 x64 redistributable)

Linux 64bit executables:

MacOSX 32/64bit universal for Intel-Macs:

NOTE: there is a known bug in NVIDIA drivers when using the 32bit executable with Windows 64bit, just use the 64bit executable to fix the problem.
