These are fantastic results, I'm delighted to see such huge performance improvements, roll on the ?ber-benchmark!

Hurray to AMD! Power management patches ARE epic!
AMD finally got it right! I'm proud to confirm their "epic" power management patches also perform greatly on HD5000-based GPUs.
For me, HD5000-series desktop GPU with dpm power management is about 10C cooler than it would be "by default" without setting low power profile by hands. And no screen blinking on re-clock. And GPU goes up very fast, so heavy loads haven't degraded in terms of performance. Really noteworthy improvement!Last edited by 0xBADCODE; 16 July 2013, 12:01 PM.

I think we have to give Michael more time to finish the benchmarks.
I bet the final benches will be massive.
time to install steam and play dota 2.

Fantastic. performance temperature and wattage review versus catalyst will be exciting!

Please bench a10-5800K because a10-6800k is way too immature to be interesting. Also please bench both LLVM and sb backends and don't forget catalyst (no need for 3.10, 3.11 with dpm off is enough). Pretty please?
P.S.
Nice selection of benchmarks but please add heaven and left 4 dead 2 to the mix.Last edited by darkbasic; 16 July 2013, 11:51 AM.

Everybody already knew, that higher clocks get higher performance. Where is the power consumption graph? Where is the comparison to Catalyst? Did you set the old Power-management to powersave or performance (what clocks were chosen)?
Also, looks like Urban Terror is bottlenecked somewhere other than the GPU (or at least the GPU/VRAM clocks didn't make much of a difference).

Do I understand it right? The open source drivers will be in a few cases faster the propertiary ones?

Previewing The Radeon DPM Performance On Linux 3.11
Phoronix: Previewing The Radeon DPM Performance On Linux 3.11
As promised, now that Linux 3.11-rc1 has been released, it's time for the new dynamic power management support of the Linux 3.11 kernel for AMD Radeon graphics. This first article previews the possible OpenGL performance gains for an AMD APU when enabling "DPM" for allowing the graphics core to properly re-clock based upon its workload.
