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.

Open-Source RadeonSI Gallium3D vs. AMD Catalyst On Linux

Towards the end of June I published AMD RadeonSI Gallium3D benchmarks, the open-source Linux graphics driver supporting the Radeon HD 7000/8000 series hardware on Linux. While the alternative to the Catalyst driver can accelerate OpenGL, it's very slow. Open-source driver benchmarks were shown in that article compared to older generations of AMD Radeon hardware backed by the mature R600 Gallium3D driver. In this article are benchmarks comparing the open-source "RadeonSI" driver to the proprietary AMD Catalyst GPU driver on the Radeon HD 7850/7950 graphics cards. As an additional driver reference point were also Radeon HD 7950 Cayman results; all testing happened from Fedora 19 Linux.

The First Benchmarks Of Unity On XMir: There's A Performance Hit

With Thursday's announcement that Mir will ship by default in Ubuntu 13.10 on the desktop, many Ubuntu users were caught by surprise that this experimental display server will be ready by October. Up to now, Ubuntu 13.10 was expected to continue using an X.Org Server by default on the desktop (with only an experimental option for Mir) while the new Ubuntu Touch project would be using Mir on mobile devices, until next year. With the pressed timeline for the migration to Mir, at Phoronix we have already carried out our first Mir benchmarks. In this article are the first benchmarks of Intel graphics when running on Ubuntu 13.10 with a native X.Org Server (as done now on current Ubuntu Linux releases) and then when deploying the same Unity desktop environment atop XMir with the Mir unity-system-compositor.
