12-Way Radeon Gallium3D GPU Comparison
When running Nexuiz, the OpenGL performance results are pretty much as expected between the different graphics cards in terms of their relative performance.
When running OpenArena 0.8.5 the results are also in line with expectations for this older game that isn't demanding in terms of modern OpenGL usage. Worth noting from these results though is the strong performance of the Radeon X1800XL/X1800XT on the R300g driver compared to the newer graphics cards on the R600g driver. These old R500 graphics cards were competing with mid-range Radeon HD 4000 series graphics cards.
