    Phoronix: Intel SNB Linux Driver Can Out Run Windows Driver

    While last week we reported Intel Sandy Bridge graphics support is still troubling in Ubuntu 11.04 and also the support broke at the last minute in Linux 2.6.39, there's really good news to report this week from the Sandy Bridge Linux land. When using the very latest working Linux driver code, in many cases the OpenGL performance of this open-source driver stack is now faster than Intel's official Windows 7 driver.

    Correction - this is already implemented in the open-source stack, you just have to turn it on.

    I'm not sure if this says more about the Intel Linux driver or the Intel Windows driver. But it's good news to have the hardware be competitive in Linux, I suppose, like the proprietary drivers do for ATI and NVidia hardware.

      I'd really like to see some demo's compared on windows and again under wine to see if this is a fluke for "Linux Optimised" games or true for all graphics rendering

        Am I the only that, just seeing the first two screenshots of Windows 7 and Ubuntu on the first page, thinks that Windows visually looks like total crap in comparison to Ubuntu?

          Personally I've always found Windows to look rather bad.
          I never understood how people could find the new Windows 7 taskbar attractive, to me even the Windows Vista one looked better ^^

          OnT: Interesting numbers, indeed.
          For my next laptop I might go for a Sandy bridge/Ivy bridge solution instead of NVidia.

            The Intel Linux driver also lacks features such as Quick Sync Video, InTru 3D Technology, Intel Wireless Display, Intel Flexible Display Interface, and other technologies currently only found in their Windows driver.
            That's beyond silly. The Linux driver obviously does support FDI.

              I guess that after all the bad publicity Intel realy had to do something to make up for it.

                If they can make the Intel Linux driver completely better than the windows driver, maybe they'll be willing to devote their efforts toward converting to Gallium3d.

                  Give Gallium some time. Intel had bad regresseion with TTM. They made it clear that they didn't want to make such a radical driver change again soon. They're probably working on it behind closed doors

                    Intel Windows driver - which version was used?

                    Intel recently announced 15.22 driver (15.​22.​1.​2361/15.​22.​1.​64.​2361) with OpenGL3.1 support - was this version used to capture performance on Windows?

                      Yeah, I thought so too. Not to mention in terms of functionality and space taken on disk. I never actually seen the two side by side so windows 7 never struck me as terribly ugly. However, I'm sure deanjo is just around the corner to tell you why windows 7 looks so much better than ubuntu.

                      Back on topic, nice to see at least one linux graphics driver outperforming the windows equivalent

                        I'd wait for the mobile version of the A8-3550.

                          on Lightsmark's side Linux's performance actually better than Windows.
                          it is the regression that causing performance lag.

                          just revert this commit, double performance
                          http://cgit.freedesktop.org/mesa/mes...d9859189a0ab0b

                          https://bugs.freedesktop.org/show_bug.cgi?id=34968

                          actually Linux driver now supports more extensions than Windows. Only thing is left performance optimizations on specific extensions.

                            Question is which one would actually give me best 3D performance with open source drivers.
                            I am not all that sure it would be the integrated HD 6550 of A8-3550.

                              One thing that isn't clear to me... wouldn't the rights to use the patented technologies have been paid for by purchasing the hardware? [it's not like vendors sell their drivers]

                              I understand that there might be an interest to protect proprietary information behind a technology, or hide implementation details of DRM protections... but if there is an independent S3TC implementation wouldn't I have the right to use it simply because I have the hardware

                              [yes I realize legal agreements are hardly written that way...]
