Raspberry Pi single board alternatives

[Accablant]

I have now been using openplotter for a couple of weeks on Raspberry Pi 4, 4GB version, for sail routing in Finland and Estonia, running o-chart vector charts on opencpn for both countries. Like some others have already reported, RPIO just does not seem to have enough gpu power to do the job on a screen resolution higher than 1024x768. But there are a plenty of single boards around, so I am wondering if someone would have tested alternatives to recommend? The list of potential candidates includes at least Orenge Pi 4B, odroid XU4, ASUS tinkerboard s and rock pi 4, all sporting some versions of Mali gpu
