"real" odroid c0 power consumption...?

Unread postby jit » Wed Feb 08, 2017 8:25 pm

Hello all,

reading specs of C0, I can see that it should consume 0.5A "in most cases"... but what are "most cases" ?

I just want to know what is the maximum power consumption with a bare C0, when CPU+GPU are 100% used, but no usb plugged
I can't find the information maybe someone already did such measure ?

If not, I'm going to do it by myself, and post result here ;)

HDMI connection + Ubuntu Desktop + Chromium web brower + Octane benchmark = 0.3~0.4Amp at 5Volt.
If we plug a USB mouse and a keyboard, total power consumption could be 0.5Amp in peak.

Please measure and share the result.
But I'm not sure how to make 100% load on CPU and GPU in parallel.

Ok, I did some test, but like you its not 100% on CPU+GPU... I used games for testing, has this maybe a "true life" use case of CPU + GPU usage.

What I used is : HDMI in 800x480, 1 usb wireless dongle for keyboard + integrated mouse, all running debian jessie with a very light WM.

- If no sdcard, no emmc, no usb : 0.12A
- If no sdcard, no emmc, wireless keyboard dongle : 0.15A
- Boot, without X and no login : 0.26A
- Playing Astromenace : 0.38A
- Playing Aquaria : 0.32 - 0.40A
- Playing Hurrican: 0.28 - 0.34A
- Playing RVGL : 0.30 - 0.36A

When playing Aquaria, CPU was around 80% usage, I guess that GPU was working hard too.
So I would say with no HDMI and no USB, the board should consume no more than 0.4A with CPU and GPU near full load...

Thank you for sharing the informative data to build a battery powered portable game console.
It could be a power consumption table in the real world. :D

BTW, how did you measure the power consumption?
I used this SmartPower2.
