Here's what hardinfo in Ubuntu 13.10 shows if that's helpful:fatdog wrote: Meanwhile, please try the script I posted in the first post (radeon-dpm.sh); if you're after higher performance then set it to "high". Otherwise set it to "low" or even "auto" if you wish. If you could do a comparison between these levels it would be appreciated, so we can decide on what power levels we want to ship on the next release. I have done my own tests and the result is inconclusive (ie I don't see much difference in terms of performance, but I do see a lot of difference in power savings). May as well compare with 621 release running with Catalyst.

I'll try running the script when I get back in fatdog64
EDIT:
I get an error when I run the script:
# sh radeon-dpm.sh
radeon-dpm.sh: line 15: echo: write error: Invalid argument
