    Phoronix: AMD Catalyst 14.6 Does Slightly Better With APITest OpenGL Tests

    Last month I published some benchmarks where NVIDIA slaughtered AMD's Catalyst driver in APITest benchmarks, a set of OpenGL 4.x test cases. While these are just micro-benchmarks of modern OpenGL and designed for showing off potential solutions for problems to leading to lower driver overhead, there's been some improvements within the Catalyst 14.6 Beta on Linux. Up today are some new benchmarks of APITest using the latest AMD and NVIDIA drivers.

    On page 1:
    Again, I can't stress enough that this suite was never meant to compare vendor to vendor, but technique to technique. For example....
    Then Michael goes on to show a bunch of benchmarks comparing vendor to vendor...

      Because AMD PR requested new benchmarks be done from the new driver given the last "slaughtering" article given the new driver...

        AMD PR was never the smartest
        are they engineers at all?

        is it architecture/hardware related?

          I think it would have been interesting to see the difference between current and previous catalyst, to see the changes.

            still, Graham Sellers is usually realistic unlike most of amd pr machine. hope that future driver improvements he mentioned really work for them. well, it would be good for everyone if they did

              Fully agree!

                I guess it was exactly this what AMD PR actually intended by the request.

                  I miss his posts about OpenGL...

                  Might be he just busy with SIGGRAPH.

                    Does APITest also work with the open drivers ? It'd be interesting to see how they compare in such "exotic" tests against closed source stuff.

                      No, these tests needs GLSL 4.10 and some extensions for some of the tests are i guess only available in nvidia implementation .

                        I greatly appreciate your honesty and bluntness. While I wholeheartedly support AMD's recent efforts toward linux, if they don't want such harsh criticisms, they need to step things up. Look at nvidia - a couple years ago, they had some pretty faulty drivers in some cases, they had no intention on supporting anything open source, and they had no intention on supporting optimus. Moments like Linus' flipping-off-nvidia moment, Valve gaining interest in linux, and websites like this pointing out serious flaws in nvidia drivers have forced nvidia to completely turn things around. All we need now is some dedicated work toward nouveau.

                        But, with the rate AMD is going, we won't be needing catalyst too much longer. At this point, all I really want is some polished openCL support and crossfire support - everything else is nice but currently not holding me back.

                          Just tell them the open source driver is way better than fglrx , and that they should ditch fglrx completely and move to the open source driver in linux... :P

                            Michael You really need an option to compare current test results with similar in the past.

                            As its now. You tested ONLY vendor vs vendor.

                            Not even incremental change between previous AMD driver and current one.
                            (And current driver is old one, anyway, as AMD had troubles with real 14.6 so it needed to be pulled back :|, so Yes, those changes Graham refer to? They aren't there)

                            Not even scaling between different solutions for same problem.


                            I'm NOT saying that results are biased or incorrect. Just their usefulness is dubious as previous results could as way be reposted (for AMD...)

                              especially, since the title of the article is "AMD Catalyst 14.6 Does Slightly Better With APITest OpenGL Tests"...
                              Then it doesn't compare old vs. new driver and has 3 AMD cards and 7 NVIDIA cards in it
