    Phoronix: 8-Way AMD Gallium3D vs. Catalyst Ubuntu GPU Benchmarks

    While I'm now onto benchmarking several new NVIDIA graphics cards under Linux and also the AMD Radeon R9 290, earlier this week I ran some more open-source vs. closed-source driver benchmarks on Ubuntu Linux. Here's fresh benchmark results when comparing eight AMD Radeon graphics cards on the open (Gallium3D) and closed-source (Catalyst) drivers and running various Linux OpenGL workloads.

    A critical thing to note, these tests did not use LLVM 3.4. Which will help the 7000 series on up allot.

      Interesting to see the 270X and 7950 results on Xonotic in Ultimate setting... were there any rendering issues?

      By the way it would be nice if there were benchmarks done with AA and/or AF.

        Some cards branded as HD7000s or even HD8000s do not use the GCN architecture, so you should say "GCN cards" instead.

          Radeon 6870

          The Radeon 6870 seems to be the sweet spot according to those benchmarks - worst case being 50% performance, mostly getting close to 90%.

          I think that was also the last WLIV5 card, before they moved to WLIV4 for the 69xx and then a mixture of WLIV4 and GCN for later cards.

          (Inclusion of the latest LLVM may change the sweetspot...)

            Noted in the first set of Unigine benchmarks... And in the conclusion.

            AFAIK for the HD7XX series, all <= HD7600 are VLIW, the rest is GNC, don't know about the HD8xxx...

              Maybe AMD can provide ppa for LLVM with their work?

              It would speed up testing. (And Oibaf could add that to his drivers then)

                The names of the cards are unreadable…

                Is it just me?

                    Xonotic Ultra doesn't even work with LLVM 3.4 on HD 7950.

                      Does all the changes are in separate repo or in upstream LLVN svn?
                      Because there are a llvm debs:
                      deb http://llvm.org/apt/unstable/ llvm-toolchain main

                        I had minimum font size set to 12 in Firefox’ preferences; turning it to none makes the text readable (while at the same time making some other text barely readable because too small.)

                            Thanks for your reviews Michael, It's great to see how the open driver keeps getting better and better. I'll become a premium subscriber this upcoming Friday in thanks for your efforts.
                            The numbers look great only the 7850 looks odd in the Xonotic tests using the open driver I wonder what's different about this card? Number seems to be about half of what it should be compared to the rest of the cards in it's range.

                              Does Oibaf drivers use LLVM in r600g?

                              Just curious if the LLVM 3.4 update would make a difference there or not. Might be an interesting test for Michael to show which backend is performing better for that driver, as well.
