Following last week's completion of the Radeon driver power management tests against the AMD Catalyst driver, now it is time to turn the tables on NVIDIA. In this article are some power consumption and thermal tests when comparing the latest open-source "Nouveau" driver code against NVIDIA's closed-source proprietary driver.

Today on Phoronix are not only new benchmarks of the proprietary Catalyst graphics driver compared to the open-source Radeon Linux driver alternative when looking at the OpenGL frame-rates, but also metrics on a number of other fronts. In this article is a graphics driver comparison when looking at the system power consumption, GPU operating temperature, and CPU usage too. The results are quite interesting and not commonly looked at on Phoronix or by users.

The first of the AMD Radeon HD 6000 "Northern Islands" graphics cards launched late last year, and while the open-source Linux driver support is technically there for those interested in this alternative to the proprietary Catalyst driver, the support is still largely broken. Here is a quick look.

Last week we provided a fresh look at the AMD Radeon Gallium3D performance using the latest development code for the Linux 3.0 kernel and Mesa 7.11 library. Today we are now looking at the Gallium3D driver performance of the Nouveau driver that is reverse-engineered to support NVIDIA GeForce graphics processors.

As noted earlier in the week, the open-source AMD Radeon "R600g" driver that supports 3D acceleration on Radeon HD 2000 series graphics cards through the latest Radeon HD 6000 and Fusion graphics processors, is becoming quite fit. The driver is nearing a point of stability, is mature enough for most desktop users, and it is beginning to receive some performance optimizations and other improvements. Thanks to this recent work, plus the ongoing development of the Linux 3.0 kernel, here is a fresh set of AMD Gallium3D Linux driver benchmarks.

It has been about a month since we last delivered ATI/AMD Radeon Linux benchmarks comparing the performance of the open-source driver against the high-performance proprietary driver. Since that point there's been various improvements to the Mesa/Gallium3D driver and there's also been the merge of the latest Radeon DRM code for the next kernel, which will likely be called the Linux 3.0 kernel, but in the DRM pull request was referred to as Gardenshed. Here are these benchmarks on several different Radeon graphics cards.

For the past five months when mentioning Intel graphics at Phoronix, it's been pretty much about their latest-generation Sandy Bridge hardware and most recently about their next-generation Ivy Bridge. The talk has either been about new hardware enablement, performance improvements, or bad regressions. In this article, we are going a generation back to look at how the Clarkdale/Arrandale-Ironlake graphics performance has evolved under Linux over the course of Ubuntu releases.

While last week we reported Intel Sandy Bridge graphics support is still troubling in Ubuntu 11.04 and also the support broke at the last minute in Linux 2.6.39, there's really good news to report this week from the Sandy Bridge Linux land. When using the very latest working Linux driver code, in many cases the OpenGL performance of this open-source driver stack is now faster than Intel's official Windows 7 driver.

With the very latest open-source Linux driver code for the AMD Fusion E-350, the support is finally stable and comparable to that of other recent Radeon HD graphics processors with the open-source driver stack.

This morning after writing Intel Sandy Bridge On Ubuntu 11.04 Is Still Troubling, I proceeded to build the latest Mesa / Linux kernel / libdrm / DDX Git stack to see where the latest Intel SNB code is at and how it's running for the popular Core i5 2500K processor. Before leaving three weeks ago, everything was running great, but to much surprise, this morning it was a broken mess. Intel just regressed hard in their Sandy Bridge support for the about-to-be-released Linux 2.6.39 kernel. Whoops!
