perfomance is around these small cheap windows tablets or the intel compute stick, depending on what you want to do its fast enough. So far im happy with it especially the onboard arduino can be quite usefull if u use it in a situation where you dont have a lot of space and want to have a lot of cabling for example robots with vision…
also it has 3 usb ports compared to the compute stick for example.
i use it to track fiducials with reactivision (ps eye) and display some movies/pictures. works fine.
but: there is termical problem. the cpu is on the bottom of the board, means heat cannot escape. result: cpu clocks down to slower speeds. some poeple solve that by adding fans and better thermal paste.
fo me it was enough to just place the board vertical instead of lying flat on the desk.
