"Curious to see how the performance of the open-source ATI/AMD Linux graphics driver is evolving for aging hardware, a new round of OpenGL benchmarks were carried out on the once-popular ATI Radeon HD 4870 "RV770" graphics card. The performance was compared between the Mesa 7.11, 8.0, 9.0, 9.1, and 9.2-devel Git releases from an Ubuntu Linux system to see how the performance has changed for this driver in the past two years."
