A week ago I reported on the open-source ATI driver becoming a
lot faster thanks to the KMS page-flipping support finally landing in
the mainline Linux kernel and xf86-video-ati driver, tiling
improvements, and lots of work going into the R300g/R600g Gallium3D
drivers. The open-source ATI Gallium3D is not conclusively faster than
the proprietary Catalyst driver is, but it's becoming a much more
competitive race. In last week's article an ATI Mobility Radeon GPU was
used to illustrate these improvements, but in this follow-up article are
the Linux benchmark results for three discrete Radeon graphics cards
using the stock Ubuntu 10.10 open-source ATI driver, the last
R500-supported Catalyst Linux driver, and then the latest open-source
driver bits from the Linux 2.6.38 kernel.
