    Phoronix: 16-Way Graphics Card Comparison On Open-Source Linux

    To get October off to a good start, in this article are benchmark results of sixteen Intel HD, AMD Radeon, and NVIDIA GeForce graphics processors all being tested from the latest open-source Linux graphics driver stack. The test setup is powered by the Linux 3.12 development kernel and the Mesa 9.3.0-devel OpenGL drivers.

    thumbs up

    nice and hard work.

      Yes, nice work.

      I'm a little confused about the Unigine results though; your charts show that the frame rates are higher when using a higher output resolution. How can doing more work be faster?

        I've noticed that in tests for a while now. It could be something about hitting the monitors native resolution avoiding some slow operation, but it is definitely weird. I thought it was a typo the first few times i caught it.

          It will be nice to see AMD vs INTEL APUs comprision test. AMD products with both closed + open source drivers with 2133MHz RAM and Intel with fastest available RAM for those platforms too. Power saving test included for those platforms will be also nice.

          Anyway thanks Michael for nice test on Linux

            I'm not sure what's up with Michael's 6570. It performs much lower than expected on the first 3 pages of tests, and then performs where you would expect it to perform realtive to the other asics on the last 4 pages of tests.

              Thanks for this brilliant comparison! I already saw the separate Radeon and Nouveau results and that led me to get a Radeon HD 6000 series. I'm very happy with it. Using an open source* driver is important to me, but nouveau support for my former Nvidia card was still after many months' active development just too slow and unstable for serious use.

              * radeon driver still requires non-free microcode blob; but there again much source code of the supposedly 'open' nouveau driver is just magic numbers being shoved into registers, and comments like "not sure what this part does".

                there is no such thing as intel apu.
                it's the same architecture as a pentium D but with better cpu and gpu.
                how the hell intel has an apu?
                if that is happening the all cpu+gpu dies are apus.

                  I think APU is just being used as shorthand for "CPU and integrated GPU".

                    any way to test non-gameing performance?

                    I have been running a slightly older AMD card with multiple rotated monitors and i've found that simple text scrolling in an xterm is noticably slow. I know that the 3D gameing performance is what's sexy, but many people spend far more time not using games :-)

                    Thisis a HD6770 card with a pair of HD monitors that I've had for a few years. The card is old enough that the closed source drivers call it unsupported, so I'm looking for a replacement, but don't want to waste money on something that's not an improvement

                      Alex you've mentioned his (and others) 6570's preforming...oddly a few times in the past. Was the 6570 a particulary buggy (hardware-wise I mean) model of cards? Was there anything 'odd' or different about it compared to the rest of the 6000 series?

                        I would at least check first if a different window manager and/or another terminal emulator work any better, just in case it is an obvious programming/configuration issue causing it. Showing 25 lines of text shouldn't be too hard even for an older card, but something like GNOME Shell likely hands off more of the work to the GPU than say, XFCE or Gnome Classic might.

                          To add to the confusion, it seems there are at least 3 models of HD 6570 having different specs. And some specifications are 2 or 3x worse for the 6570 than say the 6770, so I assumed it is simply a budget card, and some of the benchmarks are simply too demanding for it to keep up? The budget end of one GPU series could easily be worse than an average card from the previous series.

                            I experimented with different window managers and terminal emulators, no significant difference

                            just to note, on a 25 line screen you don't notice that much of an issue, but on a rotated HD screen you fit a lot more than 25 lines, more like 100+

                              I'm not sure why the closed source drivers are calling it unsupported - where are you getting it from? Looking for a a Desktop HD6xxx card for 64-bit linux on the AMD website shows up Catalyst 13.4, with 13.8 in beta form.
