“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.”
