    Phoronix: The Graphics Cards On Open-Source Linux Drivers With The Best Value + Power Efficiency

    While we routinely run performance comparisons at Phoronix looking at the OpenGL performance on the latest open-source Linux drivers with a variety of different graphics cards, in this article we're not focusing only on the raw performance but also what graphics cards on the latest Radeon/Nouveau drivers deliver the best power efficiency and value (performance-per-dollar). Here's a look at a mixture of modern AMD Radeon and NVIDIA GeForce graphics cards with Mesa 11.1-devel, LLVM 3.8 SVN, and the Linux 4.3 development kernel.

    How would a couple of the common integrated Intel graphics perform in relation to these discrete cards, knowing the Intel drivers are maintained very actively?

      The power stuff is not that interesting when you know Maxwell is the best in terms of both price and power. The latest ATI nano is supposed to be efficient too but is in a whole other price range, and draws a lot of power also (225+ watts I think it was)

        Thanks for the test.

        For the radeon 285, even if there is no automatic recloking, I guess it should still be possible with command line to set performance mode to high instead of the default low.
        Shouldn't that give the best performance (in benchmarks dpm should give equivalent to high) ? I think this should be used in such comparisons, because even if we know the amdgpu doesn't have dpm support yet, it should get there soon. So for a buyer it makes sense to see the performance in high.

          I struggle to see how this will be useful, without including the per dollar performance for the GeForce cards. Only including the per dollar performance for one manufacturer's set of cards is very odd indeed.

            The tested GTX 600 series hardware I didn't see listed still for sale brand new from Amazon itself, etc.

              As far as I know, it can't be manually re-clocked higher on AMDGPU yet.

                Thanks for testing. I like that power efficiency setting.

                  I like the fact that each game has his own page
