However, I can see an interesting deviation for HD6570 from the observed trend of other chips. r600g can reach 80+ percent of the performance of Catalyst for most HD6xxx chips except for 6570, where the performance is around 10-20 percent. Do you have a theory about this difference? Maybe DPM doesn't work as intended on HD6570? I have this kind of video card, so I wanted to test it myself. The exact model of my card is: http://www.sapphiretech.com/presentation/product/?cid=3D1&gid=3D3&sgid=3D10= 87&pid=3D1176&psn=3D&lid=3D1&leg=3D0# I have installed kernel 3.11-rc6 on Fedora 19 using this koji kernel: http://koji.fedoraproject.org/koji/buildinfo?buildID=3D457463 I haven't tested Catalyst but my r600g results mostly match the ones in the article even with a different CPU.
