    Sadly, this isn't dynamic reclocking - the user needs to set the clock rates.

    I cannot express how awesome the box plot graphs are.

      Hi Michael,

      First of all, bravo on publishing such a comprehensive benchmarking article. I don't thing anyone, even on the windows side, does this.

      I currently have a MSI R7 260X which I bought in January. It was a bumpy ride initially but since the past few months I am really impressed with this GPU. My setup is Ubuntu 14.04 with stock Mesa and an updated kernel. I have seen a bunch of your articles in which your numbers for this card don't seem to match with mine. Here are the results of my furmark running at 1920x1080

      As you can see, the results are quiet different. You data shows a total points of 114 while mine is over 500. A difference of a few points is understandable but >4x difference suggests there's something wrong with the test. I have also noticed under separate articles where you have mentioned that this card gets around 10 FPS in Xonotic under high settings while I always seem to get above 40FPS. Ultra crashes though.
      IIRC the 260x needs an updated firmware, Michael probably wasn't using it.

        Those firmwares landed yesterday in linux-firmware and here in Debian Sid as package too .

          With kernel 3.15\3.16 and mesa-git your result must be much higer. My bonaire (hd 7790) - 1659 (27 fps)

            "Overall though, in the past ten years the open-source drivers have advanced a heck of a lot... "

            yeah, no joke, it's insane..

            I made made a naive approximation of % implemented of the OpenGL standard based on the amount of lines in GL3.txt are marked as DONE.



            Note that the people working on mesa drivers have gotten from sub 20% implementation with OpenGL4.0 as a target (16 of 85 extensions), to almost 75% towards OpenGL4.4 today (102 of 137 extension), in just 4 years! I guess we can thank intel to a large extent for that, but save for that pretty much without any help.. So that's quite an achievement!

            It seems some people think like: "The open source drivers are *not even working*", they really have to revise their expectations..

            If we are lucky we might see a feature complete mesa within 2 years, if OpenGL4.5 or something doesn't increase the target again, and after that optimization and working towards beating the closed drivers Or at least that is what I hope to see.

              For some reason I have an itch to buy a Radeon HD 6870 right now. Even just to play with.

                  What pop-ups are you referring to? If it's a physical window, that's not intended, so please report the URL. If it's a "welcome screen" ad overlay, that is acceptable, since it yields around 20x the revenue PER IMPRESSION of a normal ad.
