I’ve made a comparison video of the NanoPi M4, the Rock Pi 4B, Odroid N2 and the Khadas VIM3.
All have got their own strong and weak points. The Khadas excels in raw CPU power.
Here’s my video.
Comparison NanoPi M4 - RockPi4 - Odroid N2 - Khadas VIM3
I’ve just bought a Samsung Bar Plus USB3 flash drive for the Khadas VIM3. Read speeds up to 300MB/s. I’ll use this as root device now.
I’ll make a video about it with the Khadas VIM3 in a few weeks.
