Greater Radeon Gallium3D Shader Optimization Tests

After delivering preview benchmarks of the AMD Radeon Gallium3D driver's new shader optimization benchmark, Vadim Girlin, the back-end's author, has shared some complementary Linux OpenGL benchmark results.

The results I delivered today from three different AMD Radeon HD graphics results were a mixed bag using the Mesa/Gallium3D Git code as of yesterday. This experimental shader optimization back-end needs to be manually enabled through the R600_DEBUG=sb environment variable configuration.

The discussion about the R600g shader optimization performance then turned to the forums about whether the numbers made sense and reiterating that the optimizing back-end is still in its infancy. Vadim then shared some of his results of his code contribution using the Phoronix Test Suite and OpenBenchmarking.org.

Vadim's own results from a Fedora system with an AMD Phenom II CPU and Radeon HD 5750 graphics card can be found on OpenBenchmarking.org within 1304309-FO-57500792103. Embedded below are just a few of the promising benchmarks from his GLSL optimizing back-end. Additional Phoronix benchmarks from other configurations are forthcoming.
