The Battle of the Raspberries and the Oranges
We put all of the Raspberry Pi boards and Orange Pi boards through their paces to give you an idea of how these single board computers perform. We did not include the Raspberry Pi Zero because it does not belong in this league.
Raspberry Pi 3 > Orange Pi PC > Orange Pi Plus > Orange Pi One > Raspberry Pi 2
Please note: Orange Pi is not as user friendly as Raspberry Pi. Do not simply consider performance along when choosing your single board computer. You must also consider your use case, software compatibility, compatible accessories, learning curve, and requirements.
