AMD Catalyst vs. X.Org Radeon Driver 2D Performance

[GomJabbar]

Saw the following link to a head to head comparison posted on the Mandriva forum.

Conclusion:

While the Catalyst Linux driver is frequently criticized as being slow when it comes to the 2D performance, the Catalyst 8.12 driver with the ATI Radeon X1800XT graphics card had actually better performance than the open-source xf86-video-ati driver in 17 of the 28 tests performed using the Phoronix Test Suite. Though in some of the tests where the open-source ATI stack was faster, the Catalyst Linux driver was substantially slower (by up to five times or more in some of the tests). There are certainly some operations where the Catalyst driver is faster and other areas where it is not being accelerated well at all. The 2D performance of the xf86-video-ati driver should be more competitive with the introduction of X Server 1.6, which does bring some EXA improvements. On a similar note, just recently the open-source ATI stack began supporting basic 2D acceleration on the R600/700 series.
