AMD Compiler Optimization Benchmarks With GCC 4.10 (GCC 5.0)

Filed under
Graphics/Benchmarks

As a continuation to yesterday's brief GCC 4.9 vs. GCC 4.10 (GCC 5.0) comparison with the AMD A10 A-Series "Kaveri" APU, here's some benchmarks when using the GCC 4.10 development snapshot and trying a variety of CFLAGS/CXXFLAGS to see the current impact on their performance for a variety of Linux benchmarks.

GCC 5.0 Doesn't Show Much Difference Yet For AMD's Steamroller

Filed under
Graphics/Benchmarks

GCC 4.10 has been under development since the 4.9.0 release near the beginning of the year. However, at the GNU Tools Cauldron it was agreed upon that GCC 4.10 will most likely become GCC 5.0 upon its release in 2015. The GCC version scheme is also being shaken up for future releases. Years ago there was talk of GCC 5.0 being modular and more like LLVM but to date there's no "killer features" of GCC 5.0 at this point in its SVN code-base.

AMD Quietly Releases Catalyst 14.8 Linux Driver

Linux

Back on 8 August there was evidently the Catalyst 14.8 Linux driver replace to succeed the Catalyst 14.6 Beta that was last updated in mid-July. AMD didn't make any announcement about the 14.8 Linux driver update and we didn't even notice until now when a Phoronix reader stumbled across Catalyst 14.8.

Unfortunately AMD didn't publish a change-log for the Catalyst 14.8 Linux driver update so we're really not sure what (if any) significant changes made it into this latest release, but we would certainly assume there's more Linux game bug-fixes to be found in this newest version. Given it was released at the end of last week, there's not OpenGL 4.5 support expected. It's also likely too soon to expect any Linux 3.16 kernel compatibility.

Linux 3.17 Doesn't Do Much For AMD Kaveri's Graphics Performance

Filed under
Graphics/Benchmarks

Following yesterday's RadeonSI Gallium3D vs. Catalyst comparison using the new AMD A10-7800 Kaveri APU with Radeon R7 Graphics, I then upgraded to the latest Git code for the Linux 3.17 kernel to look for performance changes.

Trying The Configurable 45 Watt TDP With AMD's A10-7800 / A6-7400K

Filed under
Graphics/Benchmarks

AMD Kaveri APUs feature a configurable TDP whereby users can opt to run their A-Series APUs with a lower power consumption and operating temperature but at the cost of slightly reduced performance.

AMD Kaveri: Catalyst vs. RadeonSI Gallium3D On Linux

Filed under
Graphics/Benchmarks

With the recently released AMD A10-7800 Kaveri APU I carried out some new benchmarks comparing the open and closed-source Linux GPU driver performance for AMD with their Catalyst and RadeonSI Gallium3D solutions. When running the open-source Ubuntu driver tests, multiple versions of Mesa and the Linux kernel were used.

NVIDIA Already Publishes An OpenGL 4.5 Linux Driver

Graphics/Benchmarks
Linux

While the OpenGL 4.5 specification is fresh off the press and we haven't even seen the Khronos SIGGRAPH announcement yet, NVIDIA has already made public their OpenGL 4.5 beta drivers for Linux and Windows.

The NVIDIA 340.23.01 Linux driver is available today and provides beta support for OpenGL 4.5 and the OpenGL Shading Language (GLSL) 4.50 versions. For tapping all of the potential of OpenGL 4.5, a Fermi, Kepler, or Maxwell GPU is needed. This is conveniently the GeForce 400 series and newer, which is only what's supported now after NVIDIA dropped pre-Fermi support from their mainline Linux driver.

The Khronos Group Is Developing A New Graphics API From The Ground-Up

Filed under
Graphics/Benchmarks

Khronos announced a call for participation in a next-generation OpenGL initiative. The announcement reads, "Khronos announced a call for participation today in a project to define a future open standard for high-efficiency access to graphics and compute on modern GPUs. Key directions for the new ground-up design include explicit application control over GPU and CPU workloads for performance and predictability, a multithreading-friendly API with greatly reduced overhead, a common shader program intermediate language, and a strengthened ecosystem focus that includes rigorous conformance testing. Fast-paced work on detailed proposals and designs are already underway, and any company interested to participate is strongly encouraged to join Khronos for a voice and a vote in the development process."

Nouveau's Big Batch Of Changes Land In Linux 3.17

Filed under
Graphics/Benchmarks

Being merged into the mainline kernel code-base for Linux 3.17 was the big DRM feature pull that included enhancements to the Intel and AMD Radeon graphics drivers (among the other smaller DRM/KMS drivers), but missing from action was the open-source NVIDIA driver. The Nouveau driver changes were delayed by some last-minute bug-hunting but now a separate pull request was issued to land the Nouveau driver updates for Linux 3.17.

Next Week We Should Hear All About OpenGL 5.0

Filed under
Graphics/Benchmarks

Wednesday is the day we've been waiting for when hopefully the lid will be lifted on OpenGL 5 by the Khronos Group.

On 13 August is when the Khronos Group will be announced the next-generation OpenGL at SIGGRAPH in Vancouver. Given that it's going to be going head-to-head with DirectX 12, AMD's Mantle API, and to some extent Apple's Metal, we (and others) assume this is most likely where they're going to make the jump to OpenGL 5.0 rather than OpenGL 4.5 for the next-gen functionality.

Firefox OS media-casting stick strikes Kickstarter gold

The first Firefox OS based media player has arrived on Kickstarter, in the form of a $25 open-spec HDMI stick that supports Chromecast-like content casting. The Matchstick, which has already zoomed past its Kickstarter campaign’s $100,000 funding goal, with 28 days still remaining, was teased back in June by Mozilla developer evangelist Christian Heilmann. The unnamed prototype was billed as an open source HDMI stick that runs Mozilla’s Linux-based Firefox OS and offers casting capabilities. Few details were revealed at the time except that the device used the same DIAL (DIscovery And Launch) media-casting protocol created by Netflix and popularized by Google’s Chromecast. Read more

Open source history, present day, and licensing

Looking at open source softwares particularly, this is a fact that is probably useful to you if you are thinking about business models, many people don't care about it anymore. We talk about FOSS, Free and Open Source Software, but if we really are strict there's a difference between free software and open source software. On the left, I have free software which most typically is GPL software. Software where the license insures freedom. It gives freedoms to you as a user, but it also requires that the freedoms are maintained. On the right-hand side, you have open source software which is open for all, but it also allows you to close it. So here we come back to the famous clause of the GPL license, the reciprocity requirement which says, "If I am open, you need to be open." So software that comes under the GPL license carries with it something that other people call a virus. I call it a blessing because I think it's great if all software becomes open. Read more
