The new Gallium3D is up against the open source Catalyst 14.6 Beta, running under Ubuntu 14.04 and both the 3.14 and 3.16 Linux kernels, giving Phoronix quite a bit of testing to do.  They have numerous cards in their test ranging from an HD 6770 to an R9 290 though unfortunately there are no Gallium3D results for the R9 290 as it will not function until the release of the Linux 3.17 kernel.  Overall the gap is closing, the 14.6 Beta still remains the best performer but the open source alternative is quickly closing the gap.

"After last week running new Nouveau vs. NVIDIA proprietary Linux graphics benchmarks, here's the results when putting AMD's hardware on the test bench and running both their latest open and closed-source drivers. Up today are the results of using the latest Radeon Gallium3D graphics code and Linux kernel against the latest beta of the binary-only Catalyst driver."
