GFXBench 4.0 was released back in November for their platforms including Android, iOS, OS X, and Windows. In an interesting move, the company emailed me this morning to announce they are supporting GFXBench 4.0 on Linux. Under Linux they appear to just be supporting OpenGL (no word of OpenGL ES) while the company already announced they intend to support Vulkan later this year.
Binaries are available for free to download for Linux x86 and x86_64. I've followed up with the company about any ARM binaries since privately from some vendors I've received ARM builds of GFXBench that work on mainline Linux in the past (cough Tegra X1). If they do have a GLES/ARM binary they will allow to redistribute, it would make for some nice graphics testing on ARM boards. Sadly GFXBench is closed-source though so no manual recompilation for other architectures.
To download GFXBench 4.0 for Linux or other details, visit GFXBench.com. Some of the tests are OpenGL 3.0 while two of them are OpenGL 4.3. It should be possible to wire up GFXBench to the Phoronix Test Suite and had done so before with the private binaries so I'll be working on getting that test profile updated shortly.
