This one has a gigabit port, Orange Pi Zero is just 100 MBit/s (but adds wifi). The Orange Pi also seems to be a bit more expensive (close though).
Does this have enough HP to work as a caching proxy or mini firewall?
For simple workloads (e.g. serving static files via HTTP) I'm pretty sure it could saturate a gigabit connection.
