STORY ABOUT THE ODROID-C2

Here is the comparisons to give you better understanding of ODROID-C2.

ODROID-C2 vs ODROID-C1 vs Raspberry Pi2

Both are Linux-friendly ARM® single-board computers for various applications and purposes.

Hardware Comparison

The ODROID-C2 has many advantages over the Raspberry Pi2.

The processor is an S905 2GHz Quad-core from Amlogic with 2GByte DDR3 RAM, Gigabit-Ethernet and IR-receiver. The size of this computer is still only 85 x 56 mm with a weight of 40g, and offers silent operation, 2~5W average power usage, and instant portability, since it fits in a shirt pocket.

One powerful feature of the ODROID-C2 is an SD 3.01 standard compatible UHS-1 MicroSD card, as well as the faster eMMC module, can be ordered with the ODROID-C2, and arrives with the popular Ubuntu operating system already installed. Insert the MicroSD card into the slot, connect a monitor, a keyboard, a mouse, Ethernet and power cable, and that’s all you need to do to use the ODROID-C2! Browse the web, play games, run office programs, edit photos, develop software, and watch videos right away.

The ODROID-C2 also has a 40+7pin GPIO header to make a physical interface between the board and the outside world. The 40+7pin interface headers include PWM, I2C, I2S, UART, ADC and GPIO function.

The IR receiver and ADC features on the ODROID-C2 offer many options for building great DIY projects.

CPU and RAM performance comparison

We ran several different benchmarks to measure the computing power on the ODROID-C2. The same tests were performed on the Raspberry Pi 2, ODROID-C1, ODROID-U3 and ODROID-XU4 for easier comparison.The values of the test results were scaled uniformly for comparison purposes. The computing power of the C2 was measured to be ~2-3 times faster than the latest Raspberry Pi 2 thanks to the 2Ghz Cortex-A53 cores and much higher memory bandwidth. The high-performance 2GB DDR3 RAM is an additional advantage allowing most programs to run smoothly on the C2.

Benchmarks (Index Score)	Raspberry Pi 2	ODROID-C1	ODROID-U3	ODROID-C2	ODROID-XU4

Antutu Scores on Android5.1 Lollipop

ODROID-C2 shows around 33,700pts while ODROID-C1+ shows around 21,200pts. So you can run Android OS more smoothly. Note that the XU4 shows around 51,000pts thanks to the much faster A15 cores and Mali-T628 MP6 GPU cores. But the ODROID-C2 has higher rate of the “Performance per Dollar” probably.

Storage I/O comparison The C2 can boot from a MicroSD card or an eMMC module. The MicroSD interface supports the higher performance UHS-1 mode as well. File access of a 512MB file (read/write) on two 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!To obtain the results in the storage I/O comparison graph, type the following lines at a command prompt.
Write speed command :
$ dd if=/dev/zero of=test.tmp oflag=direct bs=8M count=64Read speed command :
$ dd if=test.tmp of=/dev/null iflag=direct bs=8M count=64

	ODROID-C2	ODROID-C1	Raspberry Pi2
MicroSD UHS-1 Read(MB/s)	36.7	32.5	19.2
MicroSD UHS-1 Write(MB/s)	15.5	14.2	13.2
eMMC Read(MB/s)	125.0	62.2	NA
eMMC Write(MB/s)	124.0	25.2	NA

Ethernet Performance ComparisonThe ODRID-C2 has an on-board Gigabit Ethernet controller. Our bi-directional streaming speed was measured at ~900Mbps.
Thanks to the doubled Tx buffer in S905, the upload speed is twice faster than C1.

	ODROID-C2	ODROID-C1	Raspberry Pi2
iperf Server on SBC (Mbit/sec)	935.0	9280	98.6
iperf Server on PC (Mbit/sec)	928.0	392.0	66.5

Test condition
Server mode : iperf -s
Client Mode : iperf -c [ip address] -P 10 -W 32k

The 4K HDMI output shows gorgeous desktop screen on 3840 x 2160 UHD resolution.
But the rendering speed is not good due to the limited performance.4K video playback on the Android OS is quite stable and fast for 4K/HEVC playback on a real 4K display.

BOARD REVISION HISTORY

Board Revision 0.0

When we first got the information of S905 and its price, we were so amazed. We had started outlining the product concept. It was rather simple. The ODROID-C1+ fulfils the most of customers’ requirement.

The hardware design of the ODROID-C2 was started from May 2015. The performance of the S905 is twice faster than S805, and it support HS400 eMMC Mode which also increase the data transfer speed two time faster. The RAM is also doubled to 2GB on C2 while the C1+ has 1GB. There are 4 x 512MB RAMs, two on top and two on bottom.

The first revision had same blue color as C1+.

This revision was used only for internal software development and evaluation.

Board Revision 0.1

It took around two months to evaluate and update the hardware design. The first revision board was on our hands in September 2015. The color of the C2 PCB is changed to black from this revision for easier distinguish from the C1+ board.

ARMv8 64bit processor requires more optimization work than our expectation. After 9months software work, we could send around 40 units of this revision to forum members in January 2016. http://forum.odroid.com/viewtopic.php?f=135&t=18683
We give special thanks to our valuable forum members for the feedback and support on this project.

We officially announced this project via our forum in February 2016.

Board Revision 0.2

This is the first mass production version.
A few missing/wrong GPIO pins on the 40pin header are corrected.
