AMD R700 2D Driver Performance Comparison
Phoronix: AMD R700 2D Driver Performance Comparison
Earlier this week we delivered results from a comparison between the Catalyst and X.Org Radeon drivers looking at the R500 2D performance. With a lot of interest having been generated from that, we have now carried out the same set of tests again but this time using an ATI Radeon HD 4850 (RV770) graphics card and the experimental EXA support.

That's better than I expected too. I was a bit worried when I saw the article since the focus has been entirely on getting the basic functions working, not performance optimization of any kind.

It would be interesting to see a comparison of the two open source drivers, radeonhd and radeon on a card that is supported by both.
What is the 2D performance of this driver vs the Nvidia proprietary driver?

Yeah, I hadn't intended on doing an R700 2D performance look this early, but it was requested by Matthew. It turned out pretty well for a basic implementation

let's say the truth: what turned out is that AMD should be ashamed of what they call a driver (fglrx). Let's just hope all this sh%$ comes to an end with a complete open source driver one day. And actually yes, do a comparison with NVIDIA proprietary driver if you can... let's see what comes out... you never know.. maybe even NVIDIA drivers suck?

If you manage to use the Nvidia proprietary driver on the RV770, I'll be really interested by your results.
Last I heard, didn't Nvidia's newest drivers produce crummy 2D performance on GeForce 8000 and newer?
In any case, I am totally ecstatic that the EXPERIMENTAL r700 code has already come this far, even surpassing the proprietary Catalyst driver in 2D acceleration. (not that fglx sets the bar very high... )
With any luck, end-users like me will have a working r600/r700 driver when Ubuntu 9.04 comes out.
