    A review of opensource driver running southern island gpu would be nice, basically the interesting points would be power consumptions(use AC socket measurement device) at full load, desktop work, idle; performance in quake engines/unigine/wine and quirks (using multimonitor, rendering errors, hangs etc). An open source from AMD is always with huge grain of salt.
    "performance in quake engines"
    really who cares 200fps or 5000fps...

    also unigine heaven is pointlesss only unigine oilrush is a good benchmark because its a real game!

    sure wine wine benchmarks are important

      No kidding. You could say that about 99% of the benchmarks Michael does, unfortunately.

      They would be more intriguing if someone went to the trouble of figuring out exactly what these benchmarks are stressing - i know on the windows side Quake 3 games for a long time were only limited by how much memory bandwidth a card had available. Not sure if that's still the case or not. At least then we'd be able to look at these tests just like a microbenchmark to see what in particular in the driver is improving or needs improvement.

        its really sad michael@phoronix do not understand computer benchmarking

        synthetic benchmarks like unigine heaven are invalid!

        benchmarks like Quake3 are invalid because NO ONE USE MORE THAN 200FPS!
        200fps only because stereoscopic view and 100fps per eye.

        Micheael really need to chance his benchmarks in a way that they are usefull.

        this means Unigine-Oil-rush instead of unigine heaven

        this means doom3 instead of quake3

        this means all results over 200fps market as invalid result. (no joke its not valid!)

        more compute tests like openCL-Bitcoin a raytracing realtime engine openCL test.

        more wine tests with engines like TA-spring.

        and wine test with ARMA2-Free edition-

          7850 would seem like an excellent card if you use most of your time in Linux with open source drivers and switch to another OS for occasional gaming. I only need the drivers to support desktop, video (xv is fine) and preferably at least basic power management.

            Those are the words of truth. However, even with Catalyst Linux desktop is quite usable.

              Do you mean with kernel 3.4 mesa will advertise OpenGL 3.0 without exporting R600_GLSL130? Looking at the code I would say it's still required, just the R600_STREAMOUT went away.

                Damn, I meant to say doom-engine benchmarks. Still got used to doom1-2 released much prior to quake, and then d3 much later than q3.
                doom engine benchmarks.

                  No, never. Better I use VM, but I want to use linux without being forced by video card drivers into installing something I donīt want.

                    Yeah, words of the truth. Difference is - if you use nvidia, you use linux 100% for everything. I like this truth much better. If Iīd prefer windows, I would use it 100% for everything - this is possible with amd & nvidia, but reverse possible only on nvidia. Less choice with AMD.

                      Happy happy

                      Wooohooo, to me it's all progressing nicely, it ain't perfect but there's a limit to what can be done by just a few people.
                      The floss drivers are working way better for me than catalyst, though I don't care about or use opengl.

                      The performance of normal gtk or qt is still lower than what I'd think is possible, and seems slower than nicely implemented software rendering (unless you're trying to do highres alpha blending).

                      The benchmarks are a bit crappy but really there aren't too many options.
                      The main gripe I have is the lack of any analysis, or practical conclusions.
                      For example there wasn't (or I missed it, which admitedly is possible) a test of the benefits of HT on compilation time, and in my experience it seems pretty significant.
                      When something weird happens the guys at anandtech, techreport, etc. usually try to undertstand what's going on, explain it or at least give some guesses.
                      Then again on linux you get very weird results just about all the time, and this is probably one of the greater weaknesses of linux (though at least we have lots of ways to fix stuff).
                      I'm guessing the lack of analysis is due to lack of time, so we should probably try doing some benchmarks on our own and submit them so Michael has a bit of breathing room.
                      All in all he is doing a lot of work, which I really really appreciate.

                        I didn't mean to imply that you do, but there are many who want/need just that. For those, buying a 7850 may well be the best choice, not a waste of money at all.

                          I have already bought the 7750, I want to test it well with g3dvl:-D

                            This! Until when we can have the luxury named power management? Sleep?

                              I'm hoping to hit at this level too.

                                Yeah, unfortunately I can't use these drivers other than for testing purposes due to missing power management.
