While the release of Mesa 9.2/10.0 is still a ways away, for those users of the Nouveau reverse-engineered open-source NVIDIA graphics driver, here are some early benchmarks for reference compared to the stable Mesa 9.0 and 9.1 series.
The benchmarks being put out this morning are just some ThinkPad W510 numbers from an Intel Core i7 720QM system with NVIDIA Quadro FX 880M graphics. Ubuntu 13.04 was in use with the Linux 3.8 kernel and Unity 7.0 desktop. Being compared were Mesa 9.2 (master), 9.1, and 9.2 branches of Mesa Git.
These benchmarks aren't for a normal Phoronix article but just being put out there for anyone curious about the Nouveau performance with the latest Mesa Git state. More thorough testing -- from multiple NVIDIA GPUs and in comparison to NVIDIA's binary Linux graphics driver -- will happen when the Mesa 9.2/10.0 release is on approach.
The system hardware/software details in full along with all of the Linux OpenGL benchmark results can be found on OpenBenchmarking.org via 1304095-FO-NOUVEAUME45. All benchmarking was facilitated in a fully-automated and standardized way using the open-source Phoronix Test Suite software.
For the most part this round of Nouveau benchmarks aren't interesting, but there are some areas where the OpenGL performance has improved over Mesa 9.0 and 9.1.
Most of the Linux game benchmark results are uninteresting with this hardware when comparing the three latest release branches of Mesa for the Nouveau Gallium3D driver.
