  • Linux on ARMThe latest ARM Linux benchmarks to share at Phoronix is a comparison of Ubuntu 12.10, Linaro 12.10, Fedora 17, and Arch Linux when running from the dual-core Cortex-A9 OMAP4460-based PandaBoard ES development board.

  • Linux on ARMGoogle announced the Chrome OS project two years ago, and with it came the first Chromebook: the CR-48. The Chrome OS concept seemed revolutionary at the time. In 2010 we were well into the latest round of questioning whether today's PCs were fast enough. The Ultrabook revolution hadn't yet begun, and the iPad was starting to gain momentum.

  • Linux on ARMAfter delivering some AMD Vishera multi-core scaling benchmarks for reference on Saturday, here's some similar tests conducted from a Calxeda ECX-1000 quad-core ARM server node.
     

  • Linux on ARMLast week I began delivering benchmarks of the low-power yet massively scalable Calxeda EnergyCore ECX-1000 ARM Server and followed the initial tests with some ARM compiler benchmarks and other benchmarks from this 5-Watt Linux Server.

  • Linux on ARMAfter yesterday publishing the first extensive benchmark results for the Calxeda EnergyCore ECX-1000 ARM Servers in the form of the 1.1GHz and 1.4GHz quad-core ARM Cortex-A9 nodes running Ubuntu 12.04 LTS and Ubuntu 12.10, here are more benchmarks to share today from the "5-Watt ARM Server" on Linux.

  • Linux on ARMEarlier this month I was down in Texas visiting the Calxeda office where for the past four years they have been busy trying to revolutionize the server market through ultra-low power ARM-based servers. This morning one of their partners, Boston Limited, is formally launching their energy-efficient "Viridis" server built around Calxeda's EnergyCore ECX-1000 hardware. In this article are the first of some public Calxeda ARM benchmarks on Ubuntu Linux while more results will be out in the coming days.

  • Linux on ARMUsing the Fedora ARM remix on the raspberry Pi, I couldn't help but noticing how slow it was. I thought it was due to the Pi's weak hardware, but since I accidentally corrupted my root filesystem on the Pi, I decided to try Raspbian for  a change.

  • Linux on ARMThe latest Linux ARM benchmarks at Phoronix are comparing the performance of Gentoo Linux against Linaro 12.08 from a 1.4GHz quad-core ARM Cortex-A9 development board.
     

  • Linux on ARMHere's the latest benchmarks of the low-cost ODROID-X, a $129 quad-core ARM Cortex-A9 development board out of Korea with ARM Mali 400 graphics. For just $129 USD, the ODROID-X development board is very interesting with packing Samsung's quad-core Exynos 4412 ARM Cortex-A9 processors running at 1.4GHz per core, Mali-400 MP Core graphics, six USB 2.0 ports, 10/100 Ethernet, and support for running Android and/or Ubuntu/Linaro.

  • Linux on ARMHere's some interesting test results recently uploaded to OpenBenchmarking.org that compares the performance of ARM Cortex A8 and Cortex A9 cores running at 1.0GHz against an Intel Atom N450. All three systems running at 1.0GHz were also running Gentoo Linux. Clock-for-clock, can the latest-generation ARM Cortex-A9 take out the Intel Atom? For the most part, yes.

  • Linux on ARMThe Linaro organization offers monthly builds of Android and Ubuntu for their member SoC vendors, but are these Linaro-optimized Ubuntu builds any faster than the normal Ubuntu for ARM images? Here are some benchmarks of Linaro 12.08 compared to recent upstream Ubuntu Linux releases.

  • Linux on ARMHere are some more benchmarks of the ODROID-X, a $129 ARMv7 development board that packs four Cortex-A9 cores along with Mali-400 graphics to provide a fairly impressive punch. There's even some comparative numbers to a Sony PlayStation 3 running Linux.

  • Linux on ARMThe Linux 3.5 kernel for Texas Instruments OMAP4 devices has finally been uploaded into the Quantal repository for Ubuntu 12.10. With the upgraded kernel release, here are some new benchmarks of the popular PandaBoard ES compared to earlier Ubuntu 12.10 development snapshots, Ubuntu 12.04 LTS, and Ubuntu 11.10 from the dual-core Cortex-A9 ARMv7 development hardware.

  • Linux on ARMBack in June there were Calxeda's ARM Highbank performance claims of delivering 15x performance-per-Watt superior performance to Intel's Xeon x86 processor. At long last, independent benchmarks of a quad-core Calxeda Highbank board are beginning to surface.

  • Linux on ARMWhen it comes to operating systems for the TI OMAP4 PandaBoard and PandaBoard ES, Ubuntu Linux is usually the winner for several reasons. However, with last month's release of Fedora 17 for ARM, how is the Red Hat sponsored distribution running on these ARM development boards? 

  • Linux on ARMLast week I shared results from the Phoronix 12-core ARM Linux mini cluster that was constructed out of six PandaBoard ES development boards. Over the weekend, a 96-core ARM cluster succeeded this build. While packing nearly 100 cores and running Ubuntu Linux, the power consumption was just a bit more than 200 Watts. This array of nearly 100 processor cores was even powered up by a solar panel.

  • Linux on ARMLast week I shared my plans to build a low-cost, 12-core, 30-watt ARMv7 cluster running Ubuntu Linux. The ARM cluster that is built around the PandaBoard ES development boards is now online and producing results... Quite surprising results actually for a low-power Cortex-A9 compute cluster. Results include performance-per-Watt comparisons to Intel Atom and Ivy Bridge processors along with AMD's Fusion APU.

  • Linux on ARMHere's an update on the LLVM/Clang vs. GCC compiler benchmarking on ARM hardware under Linux. Last month on Phoronix I shared a few basic benchmarks of GCC vs. LLVM/Clang Compilers On ARMv7 Linux. GCC 4.6.3 on Ubuntu 12.04 was doing much better than LLVM/Clang 3.0 from the Precise repository.

  • Linux on ARMWhile Ubuntu 12.04 already did a very good job at enhancing the ARM performance, Ubuntu 12.10 already has a number of performance improvements for ARM devices. With Ubuntu 12.04 for ARM there were performance improvements thanks to switching to ARM hardfp binaries by default rather than the soft floating-point version.

  • Linux on ARMWhile comparing compiler performance of different Linux code compilers on different software stacks and hardware configurations is nothing new at all to Phoronix, usually it's done on x86 hardware. However, with ARM hardware becoming increasingly common and much more powerful, here's a comparison of the GCC and LLVM/Clang compilers on a dual-core ARM development board.
