Intel Sandy Bridge Gains On Linux 3.17 Extend Beyond Graphics

Filed under
Graphics/Benchmarks
Linux

Yesterday I shared some benchmarks showing Intel Sandy Bridge HD Graphics performance increasing on Linux 3.17 for this several year old architecture. This came as a surprise but the good news is the performance improvements on this new Linux kernel don't stop with OpenGL but extend to CPU performance too.

Linux

Besides the recent work to support OpenGL Geometry Shaders for Sandy Bridge in Mesa, users of Intel "Sandy Bridge" HD Graphics can also be thankful for the forthcoming Linux 3.17 kernel. Early testing of Linux 3.17 has revealed that for at least some Intel Sandy Bridge hardware are OpenGL performance improvements with the newer kernel code.

Intel's Latest Linux Graphics Code Competes Against OS X 10.9

Filed under
Graphics/Benchmarks

Tests I carried out last month with a Haswell-based Apple MacBook Air showed Linux largely smashing OS X 10.9 with the latest open-source graphics driver code on Linux over Apple's OpenGL driver. Today I'm testing the latest OS X 10.9.4 state against the newest Linux kernel and Intel Mesa driver code on Ubuntu while this time using an older Sandy Bridge era Apple Mac Mini.

Open-Source Radeon Graphics Have Some Improvements On Linux 3.17

Filed under
Graphics/Benchmarks

Early benchmarking of the Linux 3.17 kernel have indicated faster performance for AMD's open-source Linux graphics driver thanks to Radeon DRM improvements.

There's plenty of Radeon changes for Linux 3.17 among which is properly-working AMD Radeon R9 290 (Hawaii) graphics support after these high-end GPUs were busted on the open-source Linux driver for countless months. Linux 3.17 also expands where Radeon Dynamic Power Management (DPM) is enabled, supports uncached and write-combined GTT buffers, Userptr support, and there's GPU VM improvements among other fixes and improvements.

AMD's Catalyst Linux Driver Preparing For A World Without An X Server?

Server

AMD's proprietary Catalyst Linux driver installer is interestingly being prepared for an environment without an X.Org Server.

While there's no announcement out of AMD indicating any future support directions for their Catalyst Linux driver, it seems their Catalyst driver will soon be equipped with an option for building the driver packages without X.Org Server support, a.k.a. no building of the fglrx DDX driver.

Mesa 10.2.6 Has Plenty Of OpenGL Driver Bug Fixes

Filed under
Graphics/Benchmarks

For those living on the Mesa 10.2 stable series rather than the experimental Mesa 10.3 code, there's a new point release out today.

Carl Worth of Intel released Mesa 10.2.6 as the latest bug-fix update. Mesa 10.2.6 has at least 28 bugs fixed, including many affecting core Mesa, some AMD RadeonSI fixes (affecting Hawall and Tahiti hardware), and various other fixes. Anuj Phogat contributed the most fixes at 15 followed by Marek Olšák at 4.

Mesa Now Supports Another OpenGL 4.5 Extension

Filed under
Graphics/Benchmarks

While Mesa is still racing towards OpenGL 4.0 compliance, another OpenGL 4.5 extension can now be crossed off the Mesa TODO list.

Some Mesa developers have already started tackling some of the easier OpenGL 4.5 extensions and today another can be crossed off the list. Thanks to Tobias Klausmann. GL_ARB_conditional_render_inverted is now supported by Mesa. The core work for GL_ARB_conditional_render_inverted is complete and is implemented currently by the Gallium3D-based Nouveau NVC0 (Fermi+), Softpipe, and LLVMpipe drivers. Support will surely come in time for mainline Mesa with this extension for the RadeonSI Gallium3D and Intel drivers.

Edubuntu Vs UberStudent: Return To College With The Best Linux Distro

Importantly, there are a handful of programs that are on Edubuntu that UberStudent doesn’t have, such as KAlgebra, Kazium, KGeography, and Marble. Instead, UberStudent has a smaller collection of applications but it does include some useful items when it comes to writing papers that Edubuntu does not have. So ultimately, Edubuntu includes more programs that are information-heavy, while UberStudent includes more tools that can aid students in their studies but doesn’t directly give them any sort of information.

Zotac Nvidia Jetson TK1 review

The Jetson TK1, Nvidia’s first development board to be marketed at the general public, has taken a circuitous route to our shores. Unveiled at the company’s Graphics Technology Conference earlier this year, the board launched in the US at a headline-grabbing price of $192 but its international release was hampered by export regulations. Zotac, already an Nvidia partner for its graphics hardware, volunteered to sort things out and has partnered with Maplin to bring the board to the UK. In doing so, however, the price has become a little muddled. $192 – a clever dollar per GPU core – has become £199.99. Compared to Maplin’s other single-board computer, the sub-£30 Raspberry Pi, it’s a high-end item that could find itself priced out of the reach of the company’s usual customers. Read more

New Human Interface Guidelines for GNOME and GTK+

I’ve recently been hard at work on a new and updated version of the GNOME Human Interface Guidelines, and am pleased to announce that this will be ready for the upcoming 3.14 release. Over recent years, application design has evolved a huge amount. The web and native applications have become increasingly similar, and new design patterns have become the norm. During that period, those of us in the GNOME Design Team have worked with developers to expand the range of GTK+’s capabilities, and the result is a much more modern toolkit. Read more
