"As we alluded to last week, we have been in the process of benchmarking many Radeon HD 2000/3000/4000 series graphics cards using the open-source ATI Linux graphics stack with the Mesa R600/700 DRI driver. We have now carried out our first batch of R600/700 3D tests using this constantly evolving open-source driver to provide OpenGL acceleration and here are the results.

"The R600 series graphics cards we ran for this article included the Radeon HD 2600PRO (RV630), HD 2900XT (R600), HD 3650 (RV620), and HD 3850 (RV670). The R700 series graphics cards included the Radeon HD 4830 (RV770LE), Radeon HD 4850 (RV770), and Radeon HD 4870 (RV770). For comparison we also retested a few R500 (Radeon X1000) series graphics cards since the R500 Mesa driver is more mature and those cards included the X1800XL (R520), X1800XT (R520), and X1950PRO (RV570). Originally we had tested more cards, but some of those results were lost in the previously mentioned incident and with some of the Radeon HD 4000 series graphics cards their KMS support has regressed where no signal is supplied to the monitor when using kernel mode-setting with them and a dual-link DVI monitor, like the Samsung SyncMaster 305T we used for today's tests. We will, however, be back with more open-source 3D graphics benchmarks in the near future, including a look at the R300 Gallium3D performance."
