AMD Kaveri's Open Radeon Performance Now Multiple Times Faster

Earlier this month I shared some basic OpenGL benchmarks between AMD's Kaveri APU on the Catalyst driver and the open-source RadeonSI Gallium3D driver. Now that more time has passed I'm back with another round of Linux graphics driver testing on the AMD A10-7850K, this time looking at the impact when forcing Dynamic Power Management and toggling color tiling for maximum performance.

Open-Source NVIDIA Driver Is Still Sour For Some GPUs

Nouveau, the reverse-engineered open-source NVIDIA Linux graphics driver that's been in development now for the better part of a decade, is working brilliantly for some NVIDIA GeForce graphics cards while for other NVIDIA GPUs the experience is a sloppy mess. Using the Linux 3.13 kernel and Mesa 10.1-devel Gallium3D driver code installed on top of Ubuntu 13.10, here's what the experience is like when trying a number of GeForce graphics cards with this latest open-source driver code.

AMD Radeon Gallium3D Catches Up To Catalyst For Some Linux Games

Yesterday I ran the latest RadeonSI Gallium3D vs. Catalyst AMD Linux driver comparison, effectively another round of open-source vs. closed-source GPU driver testing. In yesterday's article it was found the RadeonSI performance is improving a lot but the AMD Catalyst Linux driver remains much faster. In this article are benchmarks of the older "R600" Radeon Gallium3D driver compared to the Catalyst driver with graphics cards from the Radeon HD 6000 series and older where the open-source R600g driver provides support and in a more mature state.

RadeonSI Gallium3D Is Improving, But Still Long Shot From Catalyst

While NVIDIA's binary driver is much faster and better than AMD's Catalyst, on the open-source driver side is where AMD has been shining. While their RadeonSI Gallium3D driver for Radeon HD 7000 series GPUs and newer is not nearly as well off as their pre-HD 7000 series (R600g) Gallium3D driver, they are making progress. In this article are benchmarks showing the "out of the box" performance on Ubuntu 13.10 with the modern open-source driver, benchmarks with the latest kernel and Mesa and LLVM, and then the AMD Catalyst driver. A range of modern Radeon HD 7000 and R9 graphics processors were used for this open-source versus closed-source driver testing.

NVIDIA Is Still Killing AMD Over Linux OpenGL Performance

Back in November I published my review of the AMD Radeon R9 290 on Linux. This high-end AMD Radeon "Hawaii" graphics card ended up being a wreck on Linux: its performance was devastating. Radeon R9 290X owners have also reported their Linux performance with the Catalyst driver has been less than stellar. In new tests conducted last week with the latest AMD and NVIDIA binary graphics drivers, the high-end AMD GPUs still really aren't proving much competition to NVIDIA's Kepler graphics cards. Here's a new 12 graphics card comparison on Ubuntu.

AMD Kaveri: Gallium3D vs. Catalyst Drivers

Now having looked at the Windows 8.1 vs. Ubuntu Linux performance, carried out an initial GPU comparison, and compared several Intel/AMD processors, our latest performance investigation with AMD's A10-7850K "Kaveri" APU is looking at the Radeon R7 Graphics performance on Ubuntu Linux when using the open-source "RadeonSI" Gallium3D driver and then using the closed-source AMD Catalyst driver.

The Linux 3.13 Kernel Is A Must-Have For AMD RadeonSI Users

The Linux 3.13 kernel that will be released in the very near future is very worth the upgrade if you are a RadeonSI user -- in particular, the Radeon HD 7000 series GPUs and newer on the Gallium3D Linux graphics driver -- but other open-source graphics driver users as well may also see nice improvements in the new kernel release. Here's some benchmarks showing off the gains found with the Linux 3.13 kernel for Radeon HD and R9 graphics cards.

Intel Ivy Bridge Linux Performance Stepped Up In 2013

In continuation from last month's Intel Haswell Linux Performance Improved A Lot In 2013, here are benchmarks of Intel "Ivy Bridge" HD Graphics 4000 when comparing the performance over the past year.

Early Ubuntu 14.04 Intel XMir Benchmarks

While Ubuntu on the desktop won't be shipping with Mir/XMir by default until Ubuntu 14.04, since I did some recent Wayland benchmarks on Fedora 20, I decided to run some benchmarks of Ubuntu 14.04 in its development state when comparing the OpenGL gaming performance of running through the X.Org Server (the default) versus running Unity 7 with XMir.

Intel Celeron, Pentium Haswell HD Graphics On Mesa 10.1-devel

In several Phoronix articles I've already shared Mesa 10.1-devel benchmarks of this latest open-source graphics driver code currently under development. Most of the open-source graphics tests at Phoronix are done on higher-end hardware, so for this article we're checking on the latest open-source graphics performance when using the low-end Celeron and Pentium processors of the Haswell generation.
