Nouveau Benchmarks Lack Change On Mesa 9.2

Phoronix benchmarks have already shown that Mesa 9.2 dramatically improves the Intel Haswell Linux experience and that there's even some performance gains for other intel GPUs. On the AMD Radeon side, Mesa 9.2 also improves the performance for AMD hardware. How does Mesa 9.2 change the game for the Nouveau driver with NVIDIA graphics hardware? Here's some new results looking at the Mesa 9.1 vs. Mesa 9.2 performance for Nouveau, the reverse-engineered open-source NVIDIA graphics driver.

AMD Fusion Linux Gallium3D Performance Has Improved A Lot

The performance of the open-source AMD Radeon Linux graphics driver for AMD Fusion APUs has improved a lot, but the Gallium3D driver performance still isn't yet on par with the AMD Catalyst binary driver. In this article are a variety of tests from an AMD APU including with the Linux 3.11 dynamic power management support, Mesa Git, and when using the R600 SB shader optimization back-end.

AMD Gallium3D & Catalyst Drivers Compete Against Windows

While this week we published benchmarks that showed how NVIDIA's Linux driver can compete with Windows 8 -- when using the closed-source drivers and not the open-source Nouveau solution -- and that even the FreeBSD NVIDIA performance is competitive, this isn't the case for AMD's drivers. From the same Core i7 Haswell system as used for the NVIDIA testing, AMD Radeon graphics cards were tested on Windows 8 and Linux. It wasn't a surprise that the open-source Radeon Gallium3D was much slower than Catalyst, but took us off guard a bit was that the Linux Catalyst driver does take some noticeable performance hits over the Microsoft Windows driver in some OpenGL workloads.

Radeon DPM Is Fantastic For Power Use, Thermal Performance

One of the most exciting features of the upcoming Linux 3.11 kernel is the open-source Radeon driver's support for dynamic power management (DPM). We have already done preliminary benchmarks and found that Radeon DPM can boost the GPU's performance in cases where the boot clock speeds are slower than their rated frequencies (as in the case of AMD APUs and modern high-end GPUs). For other GPUs, Radeon DPM can lead to lower power consumption and better operating temperatures. Here's looking at the Linux Radeon DPM performance with the Linux 3.11 Git kernel.

R600 Gallium3D Loses To AMD Catalyst Legacy Driver On Windows 8

For those ATI/AMD customers with graphics cards of the Radeon HD 2000/3000/4000 generations, they are supported by the "Catalyst Legacy" driver but this older proprietary driver branch is seldom updated for new Linux kernel and X.Org Server releases. Thus, the only real option for those with these older Radeon GPUs is to use the open-source Radeon Gallium3D graphics driver. But how does this driver compare to the still-maintained Catalyst Legacy driver for Windows 8? Here are some benchmarks.

Mesa 9.2 Can Boost Intel Haswell Graphics 30~40% On Linux

Yesterday I shared open-source Linux graphics benchmarks showing the Intel Ivy Bridge performance improving on Mesa 9.2 over the earlier releases of this important open-source Linux graphics driver component. However, for the latest-generation Intel "Haswell" graphics, Mesa 9.2 is an even more important upgrade. Here's a look at the performance benefits in moving from Mesa 9.1 to the soon-to-be-released Mesa 9.2.

Mesa 9.2 Brings Some Performance Improvements For Intel IVB

With Mesa 9.2 due to be released next month, here's the very latest Git benchmarks of Mesa 9.2-devel on an Intel Core i5 Ultrabook with HD 4000 "Ivy Bridge" graphics compared to the stable Mesa release versions going back to Mesa 8.0.

Previewing The Radeon DPM Performance On Linux 3.11

As promised, now that Linux 3.11-rc1 has been released, it's time for the new dynamic power management support of the Linux 3.11 kernel for AMD Radeon graphics. This first article previews the possible OpenGL performance gains for an AMD APU when enabling "DPM" for allowing the graphics core to properly re-clock based upon its workload.

Mesa 7.11 To Mesa 9.2 R600 Gallium3D Performance

For those with older generations of AMD/ATI Radeon graphics processors that may not be running the very latest Mesa Gallium3D driver release, here are benchmarks comparing every major Mesa release between Mesa 7.11 and Mesa 9.2.

Mesa 9.2 & The R600 SB Back-End Are Good For AMD APUs

From the AMD A10-6800K "Richland" APU I've delivered OpenGL Linux benchmarks of the Radeon HD 8670D graphics and also compared the open-source Gallium3D performance to that of Catalyst. Catalyst still reigns supreme, but in this article are some benchmarks showing the performance between Mesa 9.1 and 9.2 Git and also when deploying the experimental R600 SB shader optimization back-end.
