Yesterday I began posting quad-core ARM Cortex-A15 SoC benchmarks using an ODRIOID-XU with Exynos 5 Octa, which has a quad-core Cortex-A15 paired with the "little" quad-core Cortex-A7. In this article are more benchmarks of the Samsung Exynos 5 Octa compared to various AMD and Intel CPUs.
When the first ARM Cortex-A15 SoCs started rolling out in devices I found the dual-core A15 performance to be crazy fast for ARM and still find the Cortex-A15 performance to be great for low-power devices. Now, however, there's quad-core Cortex-A15 SoCs and even with the big.LITTLE architecture these four A15 cores can be paired with four A7 cores. In this article are our first benchmark results to share of a Samsung Exynos 5 Octa with a 1.6GHz Cortex-A15 configuration paired with a quad-core Cortex-A7 processor.
Every once in a while Phoronix readers that see photos of my office setup inquire about the glass computer desks I use. These particular desks are very functional, built well out of glass and metal, and are surprisingly affordable.
The 1.0 release of UPower, the abstraction layer for enumerating power devices and other power-related tasks that were formerly handled by HAL and then formerly known as DeviceKit-Power, is approaching.
The latest open-source work being done for improving Linux thermal monitoring and tuning is the TMON project that hopes to be mainlined within the Linux kernel.
Imagination Technologies, a name notorious amongst Linux users largely over the company's shoddy Linux driver support for their PowerVR graphics cores, unveiled a new processor core today. Announced today in London was Imagination's first MIPS "Warrior P-Class" CPU core.
ARM and other Linux stakeholders are still working to bring power-aware scheduling to the kernel.
A set of eight patches were published today for the Linux kernel that implement an extended hardware error log driver that provides enhanced Intel MCA event logging. With this driver, certain errors are more useful for users like being able to report the particular memory RAM DIMM where a memory corrected error happened and other detailed information not currently exposed via the Linux kernel.
As first reported yesterday on Phoronix, there's a new effort to raise one million dollars for a LGPLv3-licensed FPGA-based shader-supported graphics processor. Today the Kickstarter campaign kicked off with details in full on this new project.
A company is going to attempt to open-source their graphics accelerator 2D hardware design under the LGPLv3 license. Additionally, they claim for one million dollars they would be able to come up with a 3D shader-based open-source graphics accelerator.
UPower 0.9.22 was released today as mostly a bug-fix release but there's also a couple of new items.
The Lima graphics driver for open-source ARM Mali GPU support on Linux has some performance advantages of ARM Holdings' binary blob, but there's no upstream interest in having the driver mainlined in Mesa.
Rob Clark of the fast-growing Freedreno project provided a status update earlier this week at the X.Org Developers' Conference concerning his open-source ARM Qualcomm graphics driver, the Lima driver for ARM' Mali, GRATE for NVIDIA's Tegra, and Etnaviv for Vivante graphics hardware.
As a forewarning if you use LM-Sensors' sensor-detect program for detecting available hardware sensor/monitoring drivers of your system hardware, the open-source program is causing "serious trouble" for some newer hardware.
Yesterday's exciting news from LinuxCon NA 2013 was Gabe Newell's keynote where he talked about Linux as the future of gaming and exciting news coming next week. Today the interesting topic at LinuxCon is about IBM investing another billion dollars towards Linux and promoting its POWER architecture.
Apple released the iPhone 5S today and it's powered by their own A7 chip, which is a 64-bit ARM SoC and claims to be up to twice the CPU and graphics performance of its predecessor. The Apple A7 SoC has over one billion transistors and its interesting to see it being a 64-bit processor while ARM doesn't yet have out its own 64-bit chips in the wild yet. While the A7 is interesting, Apple isn't yet ready to comment on the compiler support.
PengPod, a low-quantity Linux tablet vendor, released the PengPod 1040 tablet today that they claim will "transform the PC and Tablet world by merging both elegantly together to fit any lifestyle." But will it really pan out?
While 4K resolution monitors are still extremely expensive, there's growing curiosity over support for 4K monitors by the open-source Linux graphics drivers.
The input merge happened for the Linux 3.12 kernel merge window. When it comes to input drivers for this next major Linux kernel release, the main addition is a Slidebar driver for Lenovo Ideapad laptops.
For those interested in more of my personal views on Linux hardware support, good Linux-compatible hardware, and other open-source/hardware/benchmarking related topics, earlier this week I was on the Everyday Linux podcast talking about such Phoronix topics.
Among the ARM changes for the mainline Linux 3.12 kernel is adding platform support for the Allwinner A20 and A31 SoCs along with continued work on NVIDIA's Tegra 4 support.
Many Phoronix readers seem to be infatuated by the MIPS-based Loongson systems, while the hardware is hard to find -- and even if you manage to find it in western markets, it's very expensive. For those fond of the Loongson processors and happen to have a Radeon chipset, Lemote is playing around with Radeon UVD video acceleration.
For those curious how the performance of System76's high-end Linux laptops have evolved over the past two years, here are some benchmarks comparing the latest Gazelle Professional "Haswell" laptop against the Serval Professional from the Intel "Sandy Bridge" days.
Up for some quick Linux benchmarking this Friday afternoon are tests of the Toshiba Q Series HDTS212XZSTA 128GB SATA III Solid State Drive. This SSD drive has been pitted against five other HDD/SSD disk drives on Ubuntu Linux for some interesting performance tests.
The Allwinner A10 and A13 video decode support has been reverse-engineered as open-source.
While x86_64 hardware has been very common for years and it's now almost impossible to find new PC hardware that is x86-only, the Ubuntu download pages have continued to recommend the 32-bit version of Ubuntu Linux by default for new desktop installations. Fortunately, that may finally change.
A new crowd-funding campaign seeks to produce "the first truly free and fully open-source computer utilizing only non-proprietary hardware and software under the GNU General Public License."
During the first day of the latest virtual Ubuntu Developer Summit, there were some brief remarks made concerning the state of the NVIDIA and AMD Catalyst binary drivers in supporting the Mir Display Server for Ubuntu.
As soon as Apple launched their Haswell-based MacBook Air I purchased the "ultrabook" for its long battery life, great build quality, and impressive design. However, running Linux on the 2013 MacBook Air has been a pain. It wasn't running cleanly but it looks like the major kernel booting problem comes down to a UEFI interaction issue.
For those wondering about using the Oculus Rift VR system on Linux for a virtual reality 3D gaming headset, it should work just fine on your favorite Linux distribution.
