ODROID-C4 (Hardkernel) 4GB RAM Cortex-A55 2.016GHz SoC Amlogic S905X3 Mali-G31

ODROID-C4 is a new generation single board computer that is more energy efficient and faster performing than ODROID-C2 which was introduced over four years ago as the world’s first affordable ARM 64bit computer.

The main CPU of the ODROID-C4 is built with a quad-core Cortex-A55 cluster with a new generation Mali-G31 GPU. The A55 cores run at 2.0Ghz without thermal throttling using the stock heat sink allowing a robust and quiet computer. The CPU multi-core performance is around 40% faster, and the system DRAM performance is 50% faster than the ODROID-C2.

CPU performance

Dhrystone-2, Double-Precision Whetstone, 7-zip compression benchmark results show the ODROID-C4 system performance is 40 ~ 55% faster than the previous generation ODROID-C2. USB Host

We measured the USB3 transfer speed with a UAS capable SSD.

The average ~340MB/s of throughput should be acceptable for many applications.

Since four USB host ports share a single root hub, the transfer rate will be lower if you use multiple USB3 devices at the same time. 

GPIO (40Pin Header)

The ODROID-C4 GPIO interface is similar to C2 and fully supports a 3.3Volt interface. This is beneficial for using various peripherals without complicated level shifters as with the XU4’s 1.8Volt GPIOs. Another big improvement is a faster SPI bus interface with a maximum frequency of about 100Mhz. It is significantly faster than the ODROID-C2’s 400Khz software “bit-banged” SPI.

Power consumption

Thanks to the modern 12nm fabricated S905X3 CPU, the power consumption and heat dissipation are relatively very low.

Therefore, we can enjoy a quiet and powerful computer with high energy efficiency.

Idle state: ≃ 0.18 Watt
Heavy load state: 3.1~3.3 Watt (stress-ng –cpu 4 –cpu-method matrixprod)
No cables are attached except DC power input and USB-UART debug console cable.

Note:

• The power consumption in “IDLE” is measured when a device is not being operated for 5 minutes since the CPU governor is set to ‘performance’.
• The measured power consumption is not absolute and could vary in certain conditions.
