AMD Kaveri's Open Radeon Performance Now Multiple Times Faster
Written by Michael Larabel in Display Drivers on 28 January 2014. Page 4 of 4. 41 Comments

Overall, the Radeon DPM support and color tiling make the AMD Kaveri open-source driver performance a heck of a lot faster. With the Linux 3.14 kernel we should see dynamic power management flipped on by default for Kaveri while a forthcoming xf86-video-ati update should enable color tiling by default on this latest-generation APU with Radeon R7 Graphics. In terms of how the Catalyst performance compares, we'll wait until an upcoming Catalyst driver release to facilitate the comparison -- at which point RadeonSI OpenGL 3.3 will hopefully be merged -- to do a very interesting Linux GPU driver showdown. In case you missed it, this weekend I shared a 25-way NVIDIA/Intel/AMD GPU comparison with the open-source drivers while yesterday was the matching large Catalyst vs. NVIDIA driver comparison on Ubuntu Linux.
