The folks at LoveRPi.com recently sent over an Orange Pi One when they had also sent over the ODROID-C2 $40 64-bit ARM development board for review. Here are some benchmarks of the Orange Pi One compared to several other ARM boards.
The Orange Pi One is powered by an Allwinner H3 SoC that features four Cortex-A7 cores and ARM Mali graphics. The Orange Pi One has 512MB DDR3 RAM, one USB 2.0 port, 100M Ethernet, HDMI, TF card slot, and camera interface. For anyone wanting to turn an ARM SBC into a desktop or any heavy use-cases, the Orange Pi One would be a tough fit given the specs: the Raspberry Pi 3 is spec'ed even better than this board.
