I tried HiKey970 half a year ago, but NOT quite focused on it. There seems to be NO good operating system for this particular board. During this god-damn-it COVID-19, I now have some time, and seriously would like to fullfill some of my ideas on this particular 96board:

It looks HackerBoards has done a thorough comparison of almost all types of SBCs. Let's just select the boards that we're interested in and carry out our comparison. Clearly, HiKey970's performance is outstanding.
