    Phoronix: Radeon Linux Benchmarks: Catalyst 15.3 Beta vs. Linux 4.0 + Mesa 10.6-devel

    Before ending out March, here's some new OpenGL Linux benchmarks comparing the closed-source Catalyst 15.3 Beta driver against the Linux 4.0 development kernel with Mesa 10.6 Git for the freshest open-source graphics driver code.

    I wonder why Unigine benchmarks are omitted, those are where Radeon annihilates Catalyst with up 400% performance difference.

      Use a better PPA

      That's NOT the freshest OSS driver code, not if it's still using LLVM 3.6.

      Big changes are present in 3.7.

        But it seems LLVM 3.7 is not release yet.

          Is there any performance improvement from catalyst 14.12 to catalyst 15.3 beta?

            I was surprised how much of a difference there is. It used to be the open source was nearly as fast as Catalyst, to the point where installing Catalyst was pointless. Now I'm looking at my machines wondering if I should install Catalyst 15.3 Beta. Either there's a huge regression in the drivers or AMD's Catalyst 15.3 Beta is getting serious. Even the 6870 which is usually faster with open source seems to fall apart here.

              good question

                Neither are the Mesa and kernel versions he is testing.

                I just think it's kind of silly to use git versions of those but not LLVM - either go all-git, or all-released. A frankenstein mix of the two is weird, and claiming in the article that it's the latest code is just plain misleading.

                  Good point. I would like to see newest LLVM improvements too.

                    Well Catalyst improved yes, but there is just slight perf regress in radeonsi driver it seems:

                    But looking at xonotic results, r600 seems to have big regression -40% for 6870! If is true, somone who uses r600 should check and eventually bisect that.
