  • Practical Applications and Benchmarks of GPU Computing via RenderScript and OpenCL with ARM Mali-T6XX GPU

    Linux on ARMSince the announcement of ARM Mali-T604 in 2010, ARM has explained that GPGPU (General Purpose computing on GPU), aka GPU Compute, would be one of the key features of their new Mali graphics processor, and the company now expects GPGPU to become mainstream in embedded and mobile devices in 2014 and beyond.

  • ODROID-XU's ARM big.LITTLE A7 + A15 Octa-Core

    Linux on ARMThe ODROID-XU is the latest exciting ARM development board. Rather than aiming for low-cost like the Raspberry Pi, the ODROID-XU currently offers maximum performance when it comes to open ARM development boards.

  • ARM Cortex-A15 Quad-Core Linux ODROID-XU Tests

    Linux on ARMWhen 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.

  • Comparing Linux/Arm JVMs Revisited

    Linux on ARMIt's been about 18 months since we last compared Linux/Arm JVMs, and with the formal release of the much anticipated Java SE Embedded for Arm hard float binary, it marks a good time to revisit JVM performance. The information and results that follow will highlight the following comparisons:

  • Ubuntu 12.04 Now Boots on Rockchip RK3188 mini PCs (T428, MK908, Rikomagic MK802 IV…)

    Linux on ARMAfter the release of the RK3188 Linux kernel source code last week, Ian Morrison (Linuxium) has managed to boot Ubuntu 12.04 with XFCE desktop on Tronsmart T428. However, as Tronsmart refused to release their source code, further Linux development is likely to happen on Rikomagic MK802 IV, because Rikomagic released the code for their device, so development work will be easier.

  • Raspberry Pi's Raspbian Improves Its Performance

    Linux on ARMThe Debian-based "Raspbian" Linux distribution for the Rasperry Pi ARM development board is now a heck of a lot faster thanks to recent software improvements.

  • ODROID-U2 Part 2: Benchmarking the ARM Beast

    Linux on ARMLast week's article discussed some of the broad differences between the ODroid-U2 machine and other ARM offerings. While ARM CPUs offer wonderful computing power per watt, in this article we'll dig into just how fast the ODroid-U2 can perform various tasks. I'll throw in some benchmarks from large desktop machines so you can get an idea of whether the ODroid-U2 might be fast enough to perform your given workload.

  • Mini PCs (MK802+, UG802, GK802 & iStick A200) Linux Performance Comparison

    Linux on ARMIan MORRISON (linuxium) has tested Linux with several mini PCs powered by different processors. The main point of his tests was to evaluate the performance difference between running Ubuntu 12.04 natively, or in a chroot in Android using tools such as Complete Linux Installer. I previously tried Linux on Android in ODROID-X, and found the applications start time when running from an low-end SD card pretty dismal, and the graphics performance poor.

  • Benchmarking Ubuntu Linux On The Google Nexus 7

    Linux on ARMLast month I delivered extensive benchmarks of Ubuntu Linux on the Google Nexus 10 using the recently released Ubuntu Touch Developer Preview. In that article were benchmarks from the Samsung Exynos 5 Dual (Cortex-A15) tablet against a range of ARM Cortex and Intel/AMD x86 systems.

  • Running Modern Linux On The CompuLab Trim-Slice

    Linux on ARMAt the beginning of last year I tested the CompuLab Trim-Slice, which was a great ARM-based Linux desktop for the time. While the hardware now shows its signs of aging in the fast-paced ARM world, modern Linux distributions can still be loaded up on the platform.

  • GCC Link-Time Optimizations On The ARM Cortex-A9

    Linux on ARMThe ARM Linux benchmarks continue. This time around we're looking at how the GCC LTO (Link-Time Optimization) performance fairs when running from a quad-core NVIDIA Tegra 3 Cortex-A9 tablet.

  • ARM Cortex-A15 Compiler Optimizations

    Linux on ARMThe latest in our series of ARM Linux benchmarking is looking at the impact of GCC compiler optimizations on the ARM Cortex A15-based Samsung Exynos 5 Dual.
     

  • GCC 4.8 To Bump Up Speed On NVIDIA's Tegra 3

    Linux on ARMHow's the NVIDIA Tegra 3 performance with its four Cortex-A9 cores performing under the forthcoming GCC 4.8 release? Here's some new benchmarks, similar to the recent compiler testing with the ARM Cortex-A15.

  • Benchmarking Ubuntu Linux On The Google Nexus 10

    Linux on ARMAfter spending the better part of the past week running continuous open-source Linux benchmarks on the Exynos5-powered Google Nexus 10, the first extensive benchmark results for the Nexus 10 tablet running the Ubuntu Touch Developer Preview are now available. This performance comparison from Ubuntu on the dual-core ARM Cortex-A15 powered device is compared to numerous other ARMv7 and x86 devices.

  • GCC 4.8 Compiler Performance On ARM Cortex-A15

    Linux on ARMAre there any performance improvements in store for GCC 4.8 as it affects the ARMv7 Cortex-A15 processor on SoCs like the Samsung Exynos 5 Dual? Here's some benchmark results to find out.

  • Benchmarking Ubuntu Touch Yields Mixed Results

    Linux on ARMPerformance testing of Ubuntu Linux -- in the form of the brand new Ubuntu Touch Developer Preview -- on the Google Nexus smart-phones continues to move forward, but so far findings are mixed.

  • Benchmarking The Google Nexus With Ubuntu

    Linux on ARMTests are running full-speed this weekend on benchmarking the performance of the brand new Ubuntu Touch/Tablet Developer Preview with the Google Nexus 7 and Nexus 10 devices. Here's a preview with some initial findings from performance testing these mobile ARM devices using Ubuntu Linux.

  • New ARM X.Org Driver Promises Better Performance

    Linux on ARMWhile xf86-video-sunxifb sounds like an old X.Org driver from the Sun Microsystems days for some obscure SPARC system, this driver is a fork of the xf86-video-mali DDX driver. What makes this ARM X.Org graphics driver interesting is that it promises better performance on the Allwinner A10/A13 SoC compared to the ARM vendor's official driver.

  • Fedora 18 Fails At ARM Wrestling Arch, Ubuntu, Linaro

    Linux on ARMFedora 18 was officially released this week for x86/x86_64, but the ARM version of Fedora 18 "Spherical Cow" is still under development. Fedora 18 for ARM went into beta last week and since then benchmarks were carried out comparing Spherical Cow on ARM to other popular ARM Linux distributions.

  • Linaro 12.12 Enhances ARM Linux Performance

    Linux on ARMFor kicking off a new week of Linux benchmarking at Phoronix is a round of ARMv7 performance benchmarks using Linaro 12.12. The Linaro 12.12 release from December was compared to Ubuntu 12.10, Linaro 12.10, Fedora 17, and Arch Linux on the PandaBoard ES with its Texas Instruments OMAP4460 Cortex-A9 SoC.
