Introduction of ODROID-XU Lite @$139

ODROID-XU is Samsung Exynos-5410 Octa-core based single board computer for developers.
It has 4 big Cortex-A15 cores and 4 small Cortex-A7 cores. The clock frequency of big cores is 1.6Ghz.
The XU board was launched in August-2013 and used for various applications with outstanding performance and various peripherals.

Recently we got the 1.4Ghz version of Exynos-5410 with relatively much lower price.
So we announce the lower cost version of ODROID-XU for may cost sensitive projects.
The price of XU-Lite is only US$139 while XU is US$169.
Yes, it is $30 cheaper. All other features are exactly same only except the clock frequency of Cortex-A15.

Here is a comparison chart of performance. We measured the performance with the Antutu on Android platform.

The difference of the performance is around 8%.

22 years ago(26-Aug-1991), a young student in Finland announced Unix/Minix based Operating System.
Yes, it is Linux OS and his name is Linus Tovalds.

He released Kernel 3.11-rc7 today with the celebration of 22nd birthday of Linux.
We’ve just ported it to Exynos-5410 based ODROID-XU.

Here is the booting log.

Welcome to Linaro 13.07 (GNU/Linux 3.11.0-rc7-00060-g4521a9d armv7l)

UART/USB2.0/eMMC/Cortex-A15/DRAM/Ethernet are working now.
We need to port USB3.0, GPU and many other devices on the board.

You can download the full Kernel source code via this link.
https://github.com/hardkernel/linux/tree/odroid-3.11-rc7

We already informed the performance of ODROID-XU (Exynos-5410) as described in below link.
https://www.hardkernel.com/ko/blog/how-much-faster/
Those tests were performed in Linux/Ubuntu platform.

Many people are also asking us the performance in Android platform.
So we decided to compare the performance of XU with X2/U2(Exynos-4412 Prime).
We used the famouse Antutu benchmarking tool.

This is the test result of ODROID-X2 1.7Ghz default clock.

This is the test result of ODROID-X2 2.0Ghz over clock.

This is the test result of ODROID-XU 1.6Ghz default clock.

This is the test result of ODROID-XU 1.8Ghz over clock.

For easier comparison, I made simpler charts.
XU shows obviously much higher performance than X2. 

XU vs X2 (Default clock)

XU vs X2 (Over clock)

Please note that above tests were done under Performance Governor mode instead of OnDemand Governor mode to show the maximum peformance.

ODROID-XU has 2 x SuperSpeed USB 3.0 interfaces and 4 x HighSpeed USB 2.0 interfaces.

I want to introduce the USB 3.0 feature in ODROID-XU.
There is a standard A-Type 3.0 host connector and a micro A-B OTG 3.0 connector on the board.

If you need additional USB 3.0 host of standard A-type connector,
you can use 2 x USB 3.0 ports simultaneously with a Micro A to Standard A cable.

This item is available in our e-store.

We performed a benchmarking test with our USB3.0 to SATA3 HDD/SSD interface kit.
http://www.hardkernel.com/main/products/prdt_info.php?g_code=G137448544866
This is the PCB of USB3.0 to SATA3 HDD/SSD interface kit.

Tested SSD is OCZ’s Vertex3 128GB SSD.

Test Root File System : Linaro Ubuntu with Linux Kernel 3.4.5
Read Test Command : dd if=./test of=/dev/null bs=1M count=1000 iflag=nocache oflag=nocache
Write Test Command : dd if=/dev/zero of=./test bs=1M count=1000 iflag=nocache oflag=nocache conv=fdatasync

Test result
Write Speed : 190 MB/S
Read Speed : 151 MB/S

We also made a same test with USB 2.0 port.
Wrtie Speed : 25.5 MB/S
Read Speed : 22.8 MB/S

The throughput of storage on USB 3.0 is about 7~8 times faster than USB 2.0 in the real world.

We also tested our USB 3.0 to Gigabit Ethernet adapter performance.

This iPerf test shows about 60MByte/sec transfer rate. 
It is 5~6 times faster than the 10/100 Ethernet speed.
I think we can improve the device driver and get more speed up to 80~90MByte/sec.

Let’s enjoy the SuperSpeed USB 3.0 performance with our tiny ARM embedded platform.

How Much Faster ? The ODROID-XU is based on Samsung Exynos5 Octa processor Exynos-5410 which has ARM’s big.LITTLE architecture with Cortex-A15 Quad + Cortex-A7 Quad and Samsung’s LPDDR3 2GB. Every developer wants to know the performance of new platform. The Samsung Exynos5 Octa SoC is mighty competitive as shown by following initial benchmarks compared to a Calxeda quad-core Cortex-A9 SoC, the TI OMAP4460 dual-core A9 1.2GHz SoC, and an Intel Atom D525 1.8GHz dual-core CPU plus Hyper Threading.

The first tests were done with Ubuntu 13.04 Linaro(13.07) server version and Kernel 3.4.5 to feel the speed of ODROID-XU. We used the famous Phoronix test suit for benchmarking on Linux.
Let’s start the bench marking with NAS Parallel Benchmarks which were developed by NASA. The NAS Parallel Benchmarks (NPB) are a small set of programs designed to help evaluate the performance of parallel supercomputers. The benchmarks are derived from computational fluid dynamics (CFD) applications and consist of five kernels and three pseudo-applications in the original “pencil-and-paper” specification (NPB 1). The benchmark suite has been extended to include new benchmarks for unstructured adaptive mesh, parallel I/O, multi-zone applications, and computational grids.

Starting with the scientific NAS Parallel Benchmarks test cases, the ODROID-XU with its Exynos5 Octa totally slams all of the x86 and ARM comparison hardware. The Intel Atom D525 at 1.8GHz that is dual-core plus also has Hyper Threading was also beaten by the ARM Cortex A15 quad core.

The ODROID-XU system had greater performance of 7-Zip compression.

The x264 video encoding also was found best on the ARM Cortex A15 Quad. It is getting closed to a real time encoding system.

The Smallpt is a global illumination renderer. It is 99 lines of C++, is open source, and a famous benchmarking tool.
Less is better ! ODROID-XU is better.

The Samsung Exynos5 Octa performance is quite compelling. Being found in a $149 ODROID-XU that can be loaded with Android or Linux distributions is also a very attractive bargain.
For those looking to get into ARM Linux/Android development, the ODROID-XU will prove to be a world’s best performance.

We also want to introduce a real time energy monitoring feature.
When the system performance is increasing, the power consumption and heat are also increasing. So we need to find the best balanced points of performance vs. low-energy racing.
ODROID XU+E model has 4 separated current/voltage sensors between PMIC and SoC to collect the power consumption of A15 cores, A7 cores, GPU and DDR3-RAM in parallel to optimize system energy consumption.
The real time monitor window is always visible if you enable the option. The window is transparency and overlay display. It is showing the CPU/GPU DVFS data, temperature, CPU load, voltage, current, power and other valuable information for system developers.

If you are a professional developer, you must purchase ODROID-XU+E instead of ODROID-XU.
You will meet the easy way to create energy efficient OS and application software.

Enjoy this video how we can monitor the performance and the energy consumption.
