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.
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!
