To complement the Intel Haswell Linux OpenGL benchmarks that we have been publishing on Phoronix for the past week, up today are some Intel Linux 2D performance benchmarks of Haswell with the Intel Core i7 4770K CPU. The 2D performance is comparing Intel's default UXA accelerated code-paths against the experimental SNA acceleration back-end.

With the continued speculation and FUD about the future of Wayland at a time when Canonical is investing heavily into their own Mir Display Server alternative, Eric Griffith with input from Daniel Stone have written an article for Phoronix where they lay out all the facts. The "Wayland Situation" is explained with first going over the failings of X, the fixings of Wayland, common misconceptions about X and Wayland, and then a few other advantages to Wayland. For anyone interested in X/Wayland or the Linux desktop at a technical level, it's an article certainly worth reading!

After yesterday's Intel Sandy Bridge and Ivy Bridge Linux graphics comparison using the very latest Intel Linux graphics driver, here are new benchmarks using the latest Windows and Linux Intel OpenGL graphics driver. Facing competition this morning is Microsoft Windows 7 Pro x64 and Ubuntu 13.04 with its updated open-source stack.

In revisiting the OpenGL graphics and gaming performance for an older Intel Core i5 "Sandy Bridge" Apple system, the Ubuntu 13.04 performance with Intel's open-source graphics driver is now easily surpassing Apple's OpenGL driver found in OS X 10.8.3.
Curious to see how the performance of the open-source ATI/AMD Linux graphics driver is evolving for aging hardware, a new round of OpenGL benchmarks were carried out on the once-popular ATI Radeon HD 4870 "RV770" graphics card. The performance was compared between the Mesa 7.11, 8.0, 9.0, 9.1, and 9.2-devel Git releases from an Ubuntu Linux system to see how the performance has changed for this driver in the past two years.

One of the exciting features of LLVM 3.3 that is due out next month is the final integration of the AMD R600 GPU LLVM back-end. This LLVM back-end is needed for supporting Gallium3D OpenCL on AMD Radeon graphics hardware, "RadeonSI" HD 7000/8000 series support, and can optionally be used as the Radeon Gallium3D driver's shader compiler. In this article are some benchmarks of the AMD R600 GPU LLVM back-end from LLVM 3.3-rc1 when using several different AMD Radeon HD graphics cards and seeing how the LLVM compiler back-end affects the OpenGL graphics performance.
With the AMD R600 Gallium3D shader optimizing back-end having been merged last week, new benchmarks were carried out at Phoronix to see the impact of the experimental shader optimizations on multiple AMD Radeon HD graphics cards.

Yesterday after publishing the 15-way open-source vs. closed-source NVIDIA/AMD Linux graphics comparison there were some requests by Phoronix readers to also show how the LLVMpipe software rasterizer performance is in reference. For this article to end out the month are the OpenGL performance results from nine lower-end AMD Radeon and NVIDIA GeForce graphics cards running with their respective Mesa/Gallium3D drivers compared to the LLVMpipe software driver in two configurations.

One week after delivering updated Radeon Gallium3D vs. AMD Catalyst benchmarks on Ubuntu Linux, we have to share this morning similar results for the open-source and reverse-engineered "Nouveau" Linux graphics driver compared to the proprietary NVIDIA Linux graphics driver. While the Nouveau driver has come a long way and does support the latest Fermi and Kepler GPUs, it's not without its share of shortcomings. Eleven NVIDIA GeForce graphics cards were used in this latest Phoronix comparison.

Last week after a modern Intel Gallium3D driver was proposed for mainline Mesa, a side discussion ended up being ignited about making the i915 Gallium3D driver the default for older generations of Intel graphics hardware. To see where the i915 Gallium3D driver is at compared to the i915 Classic Mesa DRI driver, here are some new benchmarks from aging Intel i945 hardware.
