With Mesa 7.9 just around the corner and it sporting a new GLSL compiler, support for new OpenGL extensions, and months worth of other changes to core Mesa and its drivers, we decided to run some benchmarks of the latest Intel Arrandale graphics processor with the past few Mesa releases to see how the performance compares. We also have ATI and Nouveau Mesa benchmarks on the way.

Over the next few weeks there are a number of new Phoronix benchmarks to be published concerning the performance of Mesa 7.9 for both the Mesa classic and Gallium3D drivers from the different GPU vendors. Included in those tests will be new Intel Mesa benchmarks of their only officially supported 3D driver using one of the Arrandale processors, but for those currently missing out on the X Developers' Summit in Toulouse or PhoronixFest at Oktoberfest, here's a bonus article. For this extra round of benchmarking, we took one of the original Intel Atom benchmarks with i945 graphics and ran it with every major Mesa release since Mesa 7.4.

For the past three years we have hosted an annual Linux Graphics Survey in which we ask tens of thousands of users each time their video card preferences, driver information, and other questions about their view of the Linux graphics stack. This year we are hosting the survey once again to allow the development community to get a better understanding of the video hardware in use, what open-source and closed-source drivers are being used, and other relevant information that will help them and the Linux community.

AMD continues to abide by their commitment to provide open-source support for their graphics cards and as proof of that this afternoon they have released their initial hardware acceleration code that supports the ATI Radeon HD 5000 "Evergreen" family of consumer grade graphics processors. While this Evergreen support isn't yet finished and for the time being is targeted towards Linux developers and enthusiasts, you can now play around with your ATI Radeon HD 5000 graphics processor on an open-source driver while having 2D EXA, X-Video, and OpenGL acceleration.

With the imminent release of X.Org Server 1.9, last week we delivered benchmarks of Intel's 2D driver performance with X.Org Server 1.9. In those tests we found Intel's UXA (UMA Acceleration Architecture) performance only changed a bit -- for either better or worse -- with the updated X Server, but today we are looking at the 2D EXA performance using ATI Radeon hardware using this soon-to-be-released X Server.

X.Org Server 1.9 is set to be released as soon as next week, has already been pulled into Ubuntu 10.10, and is part of the X.Org 7.6 katamari. While X.Org Server 1.9 does not bring many exciting end-user changes like previously releases that introduced RandR 1.2, Multi-Pointer X / X Input 2.0, and other new technologies, there are plenty of bug fixes and other minor improvements throughout the X Server. In this article, we are looking at how the Intel DDX driver performance changes when upgrading from X.Org Server 1.8.2 to the latest X.Org Server 1.9 development code.

Last month we tested out Intel's new GLSL compiler for Mesa when running the ATI Radeon classic Mesa and Gallium3D drivers to see how this GL Shading Language compiler designed by Intel employee's for their hardware and open-source driver work for the other open-source drivers, since all of the Mesa drivers will be affected once this "GLSL2" compiler is merged into the Mesa code-base by month's end. The experience using Intel's new shader compiler with the ATI Radeon graphics driver worked fine except for Warsow where serious regressions were visible, but in the other games that are capable of running off Mesa, the experience was fine. What we have been curious to test since then with this new OpenGL shader compiler has been the LLVMpipe driver -- a Gallium3D driver we have been very excited about as it finally provides a better software rasterizer for Linux by leveraging Gallium3D and the Low-Level Virtual Machine (LLVM) compiler infrastructure for accelerating the Mesa state tracker atop a modern multi-core CPU that supports SSE4 instructions. We have now finished running tests of the Intel's GLSL2 branch with the most recent LLVMpipe driver code.

Whether you are an owner of an ATI FirePro V3800 that retails for just over $100 USD, the proud owner of an ATI FirePro V8800 that goes for over $1,300 USD, or any of the FirePro products in-between, you will want to update your graphics driver when AMD puts out their next stable software update. Back in March AMD put out an amazing FirePro Linux driver that increased the performance of their workstation graphics cards already on the market (and the other Evergreen-based workstation cards that entered the market soon after) by an astonishing amount. Our independent tests of this proprietary Linux driver update found that the performance in some workstation applications had increased by up to 59% by simply installing this updated driver while other OpenGL tests had just improved rather modestly with 20%+ gains. AMD though is preparing to release another driver update for Microsoft Windows and Linux that ups their workstation graphics performance even more! We have run some tests of this new beta driver against their older driver with both their low-end and ultra-high-end FirePro products and have found the improvements again to be astonishing.

With Intel developers earlier this week expressing their plans to merge their new GLSL compiler into Mesa by the end of next month, which besides providing various shader compiler optimizations and being a better framework going forward is already set to correct 50+ bugs, we decided to try out this Mesa "GLSL2" compiler. However, as Intel explicitly stated they haven't tested this new GL Shading Language compiler that's been in development for months with any other hardware drivers (or even Gallium3D) besides their own Intel DRI driver, we decided to see how well it works with the open-source Radeon classic and Gallium3D drivers. It ended up being both good and bad.

Last quarter we compared the Catalyst and Mesa driver performance using an ATI Radeon HD 4830 graphics card, compared the Gallium3D and classic Mesa drivers for ATI Radeon X1000 series hardware, and ultimately found that even with the ATI R500 class graphics cards the open-source driver is still playing catch-up to AMD's proprietary Catalyst Linux driver. In this article we have similar tests to show the performance disparity with ATI's much older R300 class hardware. Even with Radeon hardware that has had open-source support much longer, their drivers are not nearly as mature as an outdated Catalyst driver in the same configuration.
