As was alluded to in our New Year greeting, we have been working on a massive graphics card / driver comparison under Linux. Beginning with ATI/AMD hardware, we have tested a series of graphics cards spanning the Radeon X1000, HD 2000, HD 3000, HD 4000, and HD 5000 generations using the very latest drivers. These drivers include the official Catalyst 10.12 Linux release as well as the very latest development code for the open-source Mesa and Gallium3D drivers. The results for seven ATI GPUs spanning four generations with three drivers are quite interesting.
