The Xonotic benchmarking show the RadeonSI Gallium3D performance can still be better optimized for the HD 7000 series hardware and newer.
Well, there are the results from our 25-way graphics processor comparison when using the latest Intel, AMD, and NVIDIA open-source GPU drivers on Linux. The findings come down to:
- The Intel "Haswell" HD Graphics on Linux continue to be comparable usually to a mid-range discrete AMD/Radeon graphics card (see our other Intel HD Graphics articles on Phoronix for plenty more details) though with the latest driver there are some regressions while in other tests the Haswell performance was rather strange. Fresh Intel Linux benchmarks will be coming shortly from the Linux 3.14 kernel to see if the situation is cleared up. Intel HD Graphics regardless are certainly very sufficient on Linux for desktop users, light gamers, and other tasks not requiring massive GPU horsepower.
- NVIDIA GeForce graphics cards on the open-source driver continue to struggle in large part due to the lack of power management / re-clocking support to dynamically drive up the GPU's clock frequencies to their ratings. This yields very sluggish Linux gaming performance and there's a whole lot of other issues. Hopefully NVIDIA will make a bigger investment into the Nouveau community in 2014.
- The open-source Radeon Linux graphics support is now in great shape now that the RadeonSI Gallium3D is starting to stabilize, Dynamic Power Management is enabled by default, and there's been a host of other optimizations and improvements made. The performance, OpenGL feature set, and other features still don't meet Catalyst, but the open-source driver is definitely moving in the right direction and pleasing many open-source fans.
