Kernel Space: Graphics
AMD Polaris is built using a 14nm FinFET fabrication process. The fourth generation GCN architecture for new Radeon GPUs brings a new memory controller, new multimedia cores, and a new geometry processor. Moreover, Polaris chips will support both HDMI 2.0a and DisplayPort 1.3, and are equally capable of encoding and decoding H.265 video up to 4K resolution.
Last week AMD released a new GPU-PRO Beta driver stack and this Monday, NVIDIA released the 364.12 beta driver, both of which support Vulkan and meant that Phoronix had a lot of work to do. Up for testing were the GTX 950, 960, 970, 980, and 980 Ti as well as the R9 Fury, 290 and 285. Logically, they used the Talos Principal test, their results compare not only the cards but also the performance delta between OpenGL and Vulkan and finished up with several OpenGL benchmarks to see if there were any performance improvements from the new drivers. The results look good for Vulkan as it beats OpenGL across the board as you can see in the review.
Red Hat's Adam Jackson has taken to working on X.Org Server patches for supporting GLVND within a GLX world (rather than just EGL) via the GLX_EXT_libglvnd extension. GLVND, of course, is NVIDIA's OpenGL Vendor Neutral Dispatch Library.
