The Graphics Cards On Open-Source Linux Drivers With The Best Value + Power Efficiency

While we routinely run performance comparisons at Phoronix looking at the OpenGL performance on the latest open-source Linux drivers with a variety of different graphics cards, in this article we're not focusing only on the raw performance but also what graphics cards on the latest Radeon/Nouveau drivers deliver the best power efficiency and value (performance-per-dollar). Here's a look at a mixture of modern AMD Radeon and NVIDIA GeForce graphics cards with Mesa 11.1-devel, LLVM 3.8 SVN, and the Linux 4.3 development kernel.
