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 and Android.
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.

Package includes: 
- XU4Q : Board + passive heatsink mounted

XU4Q Thermal Analysis in detail : The XU4 comes with a built-in fan which balances cooling at high performance levels. When performance is at peak level, the fan will cool to maintain performance at that high level. On the XU4Q, with the attached heat sink, it will be slightly more durable and quieter (since there is a heat sink instead of a fan).
Sacrificing 10% of performance only at 2.0GHz peak, we will be rewarded with silence. https://wiki.odroid.com/odroid-xu4/hardware/benchmark_xu4_xu4q 

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.

Technical Specifications


We ran several benchmarks to measure the computing power on the XU4. The same tests were performed on the Raspberry Pi 3 Model B, ODROID-C1+, ODROID-C2 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 ~7 times faster than the latest Raspberry Pi 3 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 super fast. The high-performance 2GB DDR3 RAM is an additional advantage allowing most programs to be compiled directly on the XU4.

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!

The XU4 has two standard-sized USB 3.0 SuperSpeed host ports. 
To measure the USB 3.0 performance, we connected an SSD via a USB-SATA bridge JMS567. We used the Samsung SSD 850 PRO 256GB model for this test. 

USB 3.0 access speed is ~10x faster than USB 2.0 on the XU4!

The XU4 has an on-board Gigabit Ethernet controller. Our bi-directional streaming speed was measured at ~910 Mbps

Thanks to the advanced technology of the RTL8153 controller, the XU4's Ethernet controller easily outperforms the connectivity solutions of prior generations.

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. 

Very affordable Seagate external 8TB HDD was connected to the XU4 via a USB 3.0 port. The Gigabit Ethernet port was connected to a Windows 10 PC via a simple switching hub. 

We copied a big 8GB file from the XU4 to the PC via a Samba connection. 
This resulted in a download speed of ~110MB/sec.  The upload speed was measured at ~95MB/sec. 
The transfer speed is very close to the high-end commercial NAS product in the market.

The XU4 is a great solution to make a DIY personal Network 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.
