Aside form desktop/notebook issue, is it really pm benchmark? Comparing powersaving capabilities of drivers in 3D gaming scenario is such an odd case. When you run games you want performance first.. It's nice to see it can save some watts under heavy load, but what does it say about impovement in power saving? It won't tell you if dpm does better job than "low" porfile from old code when system is idle (both watts/h and temps). How much it's better (performace/watts/h, temp) in 2d/video compared to profles and old dynpm.
That would be somethin closer to the cases when user wants to save power.

You're welcome
To the rest: I'd love to know what's going on with the 6770. That seems to be, by far, the most dynamic of the bunch, while the oldest card, 4770 I think, was the least dynamic.
That's suggests differences in hardware as the cause since the older cards are generally better opitmized in driver.Last edited by liam; 31 July 2013, 04:35 PM.

1. Test idle power usage. Honestly it shouldn't change much, if at all, while you are running apps. It's at the desktop that you should really see changes.
2. The line graphs were pretty much unreadable. You had black, blue, and then 4 separate shades of red that all ran together.
Only when you used a static "low" profile, the other profiles should benefit.
On 2.
Good to see I am not the only one. I am even quite good at keeping colours apart but that was a graph that was hard to interprete.Stop TCPA, stupid software patents and corrupt politicians!

Very good power management!
I can also confirm power management is very good for me on 5750 and 5770 cards. In idle states GPU are about 10C colder than they were by default, thanks to lowest frequency possible. Then they quickly increase frequency on load, so there was no noticeable performance loss either. Really remarkable improvement!
And btw, I can monitor GPU frequencies like this:
Code:while (true) do cat /sys/kernel/debug/dri/0/radeon_pm_info; sleep 1; done
Code:uvd vclk: 0 dclk: 0 power level 0 sclk: 15700 mclk: 30000 vddc: 1000 vddci: 1000
