R600g Tests Show Little Change On Mesa 9.2-devel
Now having shown that Intel Ivy Bridge graphics are faster with the latest Mesa 9.2-devel Git code and also that the Gallium3D LLVMpipe driver is significantly faster, here's a new round of AMD Radeon "R600g" Gallium3D performance benchmarks.
The OpenGL benchmarks in this article are being done from an MSI WindBox system, which has been dusted off after not being tested in a while, and sports AMD Radeon HD 4330 graphics for the Intel Atom 330 "nettop" device.
Ubuntu 13.04 was running on the Atom 330 + Radeon HD 4330 system with the Linux 3.8 kernel, Xfce 4.10, xf86-video-ati 7.1.0, and LLVM 3.2. The Mesa 9.1.1 Git code was compared to Mesa 9.2.0 Git as of this week. Swap buffers wait was disabled for the Radeon DDX throughout testing and all other settings remained the same. Benchmarking was fully automated through the open-source and industry-leading Phoronix Test Suite automated testing software.
Benchmark results in full along with other system hardware/software details and the logs are hosted on OpenBenchmarking.org within the 1304164-UT-MESA92DEV51 result file.
These Mesa 9.1 vs. 9.2-devel test results of R600 Gallium3D from the low-power HD 4330 system is just a prelude to a large multi-way Radeon Gallium3D vs. Catalyst comparison being published this week.
Support for the Radeon HD 4000 series was dropped last year from the Catalyst driver, so Radeon Gallium3D is the only real option for Linux hardware support with this aging Radeon HD 4330. Unfortunately, its performance is very low.
There isn't too much to see out of Mesa 9.2-devel, yet.
OpenArena 0.8.8 does see a nice performance improvement with this in-development release of Mesa.
The performance for many other Linux OpenGL games on this Atom 330 nettop is rather unchanged by the next version of Mesa.
Stay tuned for the extensive Radeon Gallium3D vs. Catalyst benchmarks, but in the mean time check out the rest of the results. The forthcoming results are much more interesting.
