[Phoronix] 16-Way Graphics Card Comparison On Open-Source Linux

Overall, if you read the earlier 11-Way Radeon Linux and 4-Way Nouveau comparison articles, these results shouldn't be too much of a surprise besides clearly showing side-by-side how much better the open-source Radeon driver stack is performing than the open-source NVIDIA (Nouveau) principally due to the lack of proper GPU/vRAM re-clocking support. With the current Nouveau stack on the Linux 3.12 kernel and Mesa 9.3-devel, Intel Haswell graphics are even competitive with high-end Fermi and Kepler NVIDIA GPUs.

For those making their buying decisions around using an open-source Linux graphics driver and avoiding the binary NVIDIA/AMD drivers, gamers and those concerned about performance are best off with a Radeon HD 6000 series graphics card. The HD 6000 series is the last generation supported by the AMD "R600" Gallium3D driver that is stable and supports the greatest number of features among the open-source drivers right now while delivering decent performance though not yet up to scratch with Catalyst. The newer Radeon HD 7000/8000 series hardware will be supported well in due time, but still its open-source "RadeonSI" driver isn't yet ideal.

Seems like GCN has a bit more to go on Linux

Comparing the open source driver performance is hardly a fair comparison considering that the open-source drivers still pale in comparison to the binary drivers (which I've needed to install for proper 3D acceleration on all my linux boxes).

Granted, I don't exactly own any modern hardware, and it seems all the open source support is for the newer generations only frown.gif


edit: it seems the proprietary binary drivers tell a different story, although they are a bit weak on multi-monitor and multigpu support (at least at the same time)

Coming up next will be a performance comparison for those who don't care about open-source vs. closed-source drivers but are simply concerned about maximum GPU hardware performance on Linux.

They said an updated version of the July proprietary drivers will be coming
