ODROID-C1+
The ODROID-C1+ is esteemed to be the most powerful low-cost single board computer available, as well as being an extremely versatile device. Featuring a quad-core Amlogic processor, advanced Mali GPU, and Gigabit Ethernet, it can function as a home theater set-top box, a general purpose computer for web browsing, gaming and socializing, a compact tool for college or office work, a prototyping device for hardware tinkering, a controller for home automation, a workstation for software development, and much more.

The C1+ is the latest revision of the original C1.
It replaced the original C1 in July 2015. Compared to the C1 it has :
- Standard Type-A HDMI connector - An included heat sink on board - An I2S bus to support HiFi audio add-on boards - CEC function that doesn't require the RTC backup battery - A power path from USB OTG port as well as DC barrel connector - Improved SD-card compatibility Because of the above changes, the original cases and heat sinks are not compatible. |

STORY ABOUT THE ODROID-C1+
We had received tons of requests for the following model of ODROID-W. So, we started survey for components for ODROID-W2. Finding out the right CPU was the key of this project. Our original target was similar cost and similar performance as ODROID-W. But we realised that we cannot make ODROID-W2 once we reached to Amlogic S805 quad core processor. The performance of Amlogic S805 1.5Ghz quad core processor is outperforming Broadcom BCM2835.
We launched the ODROID-C1 in December 2014 and RPi2 was released in February 2015.
Here is the comparisons to give you better understanding of ODROID-C1.

Computing performance comparisonWe ran a simple, popular benchmark called Unix-Bench, SysBench and N-Bench to compare the performance of the two boards. Tests were done using several manufacturer-provided images based on a clean install, and the “apt-get update && apt-get upgrade” commands were first run to ensure that both boards was up-to-date. The RPi2 was clocked at 900Mhz using a Sandisk UHS-1 8GB SDCard running the Raspbian OS. The C1 was clocked at 1.5Ghz using an 16GB eMMC with Ubuntu 14.04 OS. Both units were powered by a 5V/2A power supply and connected to the 1920x1080 HDMI output. |

Benchmarks(Index Score) | ODROID-C1+ | Raspberry Pi 2 | Ratio |
Dhrystone-2 | 1262.8 | 1006.6 | 1.25 |
Double-Precision Whetstone (x3) | 1318.8 | 1076.1 | 1.23 |
Nbench2.2.3 Integer ( x40) | 1208.0 | 840.0 | 1.44 |
Nbench2.2.3 | 1050.0 | 809.0 | 1.30 |
SysBench CPU ( 1/T * 50000) | 863.6 | 669.3 | 1.29 |
SysBench RAM | 998.3 | 574.7 | 1.74 |
The results show that the CPU computing benchmark is about 30% faster on the C1 and RAM memory access speed is about 75% faster on the C1. Note that above benchmark scores were converted to make an easier comparison.
Storage I/O comparison
To obtain the results in the storage I/O comparison graph, type the following lines at a command prompt. The first command tests the write speed, and the second command tests the read speed:
$ dd if=/dev/zero of=test.tmp oflag=direct bs=500K count=1024
$ dd if=test.tmp of=/dev/null iflag=direct bs=500K count=1024

If you use the eMMC storage, you can get about two to three times faster storage I/O read performance. However, an affordable microSD UHS-1 card can still achieve reasonably fast speeds thanks to the advanced SD 3.01 host controller in the S805 processor. The MicroSD card read performance on C1 is still about 1.7 times faster then RPi if you use the UHS-1 memory card.

As one can see from the testing results, the quad-core 1.5GHz ODROID-C1+ can easily outperform the Raspberry Pi 2 board. Many test results show about 140% more performance from the ODROID-C1+ platform. Even though both platforms are Linux-friendly computing devices, the performance to cost ratio is much higher with the ODROID-C1+. If you are considering a tiny computer for general purpose computing, software development, or as a project platform, the ODROID-C1+ will give you a lot more satisfaction and fun with incredible performance for a very low price.
