NOTE:
1. The active cooling fan is mounted on the XU4 board by default. It spins only when the CPU load is high and the temperature of the CPU hits a minimum threshold temperature. Like most fans, a slight hum can be expected when active.

 


 

 ODROID-XU4

ODROID-XU4 is a new generation of computing device with more powerful, more energy-efficient hardware and a smaller form factor. 
Offering open source support, the board can run various flavors of Linux, including the latest Ubuntu 15.04 and Android 4.4 KitKat and 5.0 Lollipop.

By implementing the eMMC 5.0, USB 3.0 and Gigabit Ethernet interfaces, the ODROID-XU4 boasts amazing data transfer speeds, a feature that is increasingly required to support advanced processing power on ARM devices. 
This allows users to truly experience an upgrade in computing, especially with faster booting, web browsing, networking, and 3D games.

 

The XU4 is fully software compatible with XU3!(软件完全兼容XU3,但比XU3更小巧)
However, the XU4 is more compact, more affordable and more expandable.

* Samsung Exynos5422 Cortex™-A15 2Ghz and Cortex™-A7 Octa core CPUs
* Mali-T628 MP6(OpenGL ES 3.0/2.0/1.1 and OpenCL 1.1 Full profile)
* 2Gbyte LPDDR3 RAM PoP stacked
* eMMC5.0 HS400 Flash Storage
* 2 x USB 3.0 Host, 1 x USB 2.0 Host
* Gigabit Ethernet port
* HDMI 1.4a for display
* Size : 82 x 58 x 22 mm approx.(including cooling fan)

A MicroSD card or an eMMC module is required to boot the OS. We strongly recommend an eMMC module for faster OS booting, quicker application launching, seamless multi-tasking and efficient access to the cloud.

 

NOTE:
1. The active cooling fan is mounted on the XU4 board by default. It spins only when the CPU load is high and the temperature of the CPU hits a minimum threshold temperature. Like most fans, a slight hum can be expected when active.

CPU/RAM PERFORMANCE

We ran several benchmarks to measure the computing power on the XU4. The same tests were performed on the Raspberry Pi 2 Model B, ODROID-C1, ODROID-U3 and ODROID-XU4.

The values of the test results were scaled uniformly for comparison purposes. The computing power of the XU4 was measured to be ~3-4 times faster than the latest Raspberry Pi 2 thanks to the 2Ghz Cortex-A15 cores and much higher memory bandwidth. Using the XU4 as a computer provides a "desktop like" experience, unlike the sluggish performance of most single-board computers! 
Particularly for developers, compiling code on the XU4 is about 3 to 4 times faster. The high-performance 2GB DDR3 RAM is an additional advantage allowing most programs to be compiled directly on the XU4.

SD/eMMC PERFORMANCE

The XU4 can boot from a MicroSD card or an eMMC module. An easy-access hardware switch is provided to select the boot interface (MicroSD/eMMC). The MicroSD interface supports the higher performance UHS-1 mode as well. 
File access of a 512MB file (read/write) on three different storage options shows distinct performance differences. 
The eMMC 5.0 storage is ~7x faster than the MicroSD Class-10 card in read tests. The MicroSD UHS-1 card is ~2x faster than the MicroSD Class-10 card in read tests. The MicroSD UHS-1 card provides a great low-cost option for many applications!

USB 3.0 PERFORMANCE

ETHERNET PERFORMANCE

The XU4 has an on-board Gigabit Ethernet controller. Our bi-directional streaming speed was measured at ~880Mbps. 
Thanks to the advanced technology of the RTL8135 controller, the XU4's Ethernet controller easily outperforms the connectivity solutions of prior generations

NETWORK STORAGE PERFORMANCE

These days, network storage applications like NAS and cloud services are popular. We ran the famous OMV (Open Media Vault) OS on the XU4 to measure network storage performance. 
An SSD was connected to the XU4 via a USB 3.0 to SATA bridge. The Gigabit Ethernet port was connected to a Windows 8 PC via a simple switching hub. 

We sent a big 1.6GB file from the XU4 to the PC via a Samba connection. This resulted in a download speed of ~75-85MB/sec. 
The upload speed was measured at ~70MB/sec. Even though this performance is great, we are working on optimizing it even further. 

The XU4 is a great solution to make a DIY personal cloud storage server!

Heterogeneous Multi-Processing (HMP) solution 

The ODROID-XU4, equipped with four big cores (ARM® Cortex® -A15™ up to 2.0GHz) and four small cores (ARM® Cortex® -A7™ up to 1.4 GHz), provides improved processing capabilities while maintaining the most efficient power consumption available. With the big.LITTLE™ HMP solution, the Exynos-5422 can utilize a maximum of all eight cores to manage computationally intensive tasks.

OpenGL ES 3.0 and OpenCL 1.1 for Linux and Android platforms 

The ARM® Mali™-T628 MP6 GPU offers key API support for OpenGL ES 1.1, OpenGL ES 2.0 and OpenGL ES 3.0, OpenCL 1.1 Full Profile and Google RenderScript. Mali-T628 is the GPU of choice for use in the next generation of market-leading devices, optimized to bring breathtaking graphical displays to consumer applications such as 3D graphics, visual computing, augmented reality, procedural texture generation and voice recognition. You can download the full featured OpenGL ES and OpenCL SDK from ARM Mali Developer website. It's free! 

This screen-shot shows OpenGL-ES applications and the Kodi media player with Ubuntu 15.04 Mate desktop on the HMP enabled Kernel 3.10 LTS.
