    We need an AMD APU test with the high performance profile before we can conclude that.
    this is only "theoretical" because most people use the driver in the standard settings and they don't want to tweak the driver.

    then the concluding is the same with the sentence: if you want want to be a "hacker" who tweak your driver you better buy a Intel system.

    Power profiles are obsolete! if AMD can not manage to build a "automatic" mode they are out of the race

      Why? The intel defaults are much better, so they wouldn't need to tweak the driver then.

        you are right i just FAIL.-- i forgot something in the text. i mean:

        "if you DON'T want to be a "hacker" who tweak your driver you better buy a Intel system."

        so really sorry for my failure.

          Yes, I agree they should get a dynamic option stable and enabled by default. But for measuring the open drivers on the APU, it should be done with the high profile too.

          (when will we see the clocks moved out of debugfs? It's not a debug action)

            MS WOS has a 300 Hz kernel, Ubuntu a 100 Hz one, and Ubuntu Studio a 1000 Hz
            Windows can switch to 1000Hz when needed. This happens when a multimedia timer is requested by an application. (Happens when starting Media Player, for example.)

              The current generation is already doing that. I've been an AMD fan since the glorious Athlon XP days, but a few months ago I bought a crappy Pentium G840 and the graphics performance is so much better than it ever was with my former Athlon II + 785G system. The worst part is that the HD4200 in the 785G chipset is supposed to be a little better than the Intel HD graphics in the G840. What a difference good drivers make!

              right now you get a faster cpu on intel side and a faster gpu on amd side but only if you use a closed source driver
              with opensource drivers you get a faster cpu on intel side and a faster gpu on intel side and a lower price ..LOL!
              Actually... the graphics performance with Catalyst is reasonable when it comes to stand-alone full screen 3D apps, but the desktop performance is terrible. In the case of the systems I mentioned above it's much worse than the lowly Pentium G840. I can't use the 3D variant of Unity or Gnome Shell with Catalyst.

              I would stop that sentence there. In a few more years discrete GPUs will be a thing of the past. The tendency is clearly to integrate everything into a single chip.

                the hd4200 is clearly obsolete but the APUs are not obsolete but amd just fail with opensource drivers.

                even the red-hat team for the nvida cards do it better with zero support from nvidia.

                catalyst burned me... for me its a "windows only driver".

                i don't buy hardware to use closed source drivers anymore.

                for big games like "arma2" you need the biggest card you can get but big games like arma2 do not run in linux because of this big cards are useless.

                its a linux specific "fact" not a general "fact"

                these stupid companys like nvidia and amd just kill the discrete GPU market thats so SAD...
