Linux Benchmarks – Rockchip RK3288 vs Exynos 5422 vs AllWinner A80 vs Intel Atom Z3735F

With all these Intel Atom Z3735F been released right now at a price similar to ARM based mini PCs, many people, including myself, are wondering about the performance of the low cost Intel processor against their ARM competitors. Ian Morrison just published some results from Phoronix Test Suite comparing the performance of Firefly-RK3288 (Rockchip RK3288), ODROID-XU3 Lite (Samsung Exynos 5422 BIN2), and A80 OptimusBoard (Allwinner A80) in Linux (Ununtu 12.04.5), against the performance of MeegoPad T01 (Intel Atom Z3735F) running Linux from a Live CD on a USB drive. Some of the benchmarks failed because Phoronix Test Suite got apparently confused with the file systems located on a USB drive, but at least we’ve got a comparison point, and the results are a bit confusing, as they’re no clear winner. In some tests like FFmpeg, the Intel SoC really crushed the ARM competition being at least twice as fast as […]

3D Graphics Acceleration in Linux on Allwinner A80 based Cubieboard4

Allwinner A80 is a powerful octa-core processor found in development boards and TV boxes such as Cubieboard4 or Tronsmart Draco AW80. Some early Ubuntu images and instructions had already been released for A80 Optimusboard and Draco AW80, but none of these featured GPU drivers for 3D acceleration, which to be honest, has limited advantages in Linux desktop distributions since desktop environments and most apps require full OpenGL support, i.e. not only OpenGL ES, and the only ARM SoC that can provide OpenGL support without external graphics card is Nvidia Tegra K1 SoC. Having said that GPU drivers would pave the way for smooth OpenELEC / Kodi user interface support in Allwinner A80 Linux distributions. That’s only one part of the puzzle, since the GPU normally handles the user interface, while the VPU takes care of video decoding. The good news is that CubieTech release updates images for their Cubieboard4 (CC-A80) […]

Iliad’s Online Labs Offers Quad Core ARMv7 Dedicated Servers

Iliad (Free) is a French company known to bring the price of technology down for the masses. Several years ago, they disrupted the Internet broadband market, by bringing low cost triple play broadband services to market, and more recently they entered the mobile market with 2 Euros 3G/4G monthly subscriptions. The company also owns Online.net providing hosting services, and which has recently launched a public preview for Online Labs cloud platform. Most hosted solutions nowadays relies on x86 servers and virtualization, but Online Labs instead features dedicated physical ARM servers connected to SSDs. The company call their custom-made credit-card size server modules C1 boards, completely unrelated to ODROID-C1 boards, as those are powered by a quad core ARMv7 Marvell processor with 2GB RAM, and a 1Gb/s network interfaces. These are then assembled into racks as shown below. And finally 16 racks are inserted into a chassis with a control board, […]

How to Install Ubuntu ARM64 on Nexus 9 Tablet

HTC Nexus 9 is one of the first 64-bit ARM platform with powerful ARMv8 cores (e.g. not Cortex A53) that both commercially available, and relatively affordable at $399 to $599, at least significantly cheaper than the server boards such as Applied Micro X-C1. The tablet comes with Android 5.0 Lollipop, but for those of you who wish to have an ARM64 platform running Ubuntu or other 64-bit Linux operating systems, Ubuntu installation instructions provided by Ryan Houdek, Dolphin emulator developer, might come handy, especially it won’t affect your Android installation provided you have already unlocked your bootloader. The instructions are fairly long so I won’t reproduce them all here, so I recommend you check the detailed instructions on XDA, but the short summary below may give an idea of the amount of work needed: Install dependencies such as Aarch64 toolchain:

sudo apt-get install gcc g++ git gcc-4.9-aarch64-linux-gnu g++-4.9-aarch64-linux-gnu

1	sudo apt-get install gcc g++ git gcc-4.9-aarch64-linux-gnu g++-4.9-aarch64-linux-gnu

Build a initramfs with buildroot. You’ll need to enable […]

TyGL OpenGL ES 2.0 Backend for WebKit Speeds Up Web Rendering by Up to 11 Times

ARM, Szeged University in Hungary, and Samsung Research UK have been working on TyGL, a new backend for WebKit accelerated with OpenGL ES2.0, and developed and tested on ARM Mali-T628 GPU found in Samsung ARM Chromebook. It will typically provide 1.5 to 4.5 times higher performance, but in the best cases, it can achieve up to eleven times the performance of a CPU-only rendered page. The key features of TyGL include: Web rendering accelerated by GPU – Batching of draw calls delivers better results on GPUs. TyGL groups commands together to avoid frequent state changes while calling the Graphics Context API. Automatic shader generation – TyGL generates complex shaders from multiple shader fragments, and ensures the batches fit into the shader cache of the GPU. Trapezoid based path rendering – Work in progress. It will leverage GPU capabilities such as the Pixel Local Storage extension for OpenGL ES. No software […]
