I would guess it is a rockchip processor not unlike most android sticks.
Processing Speed 1.5GHz, Operating System : Powered By Google Android 4.0, Flash 11
Built-in 1GB DDR III RAM , Built-in Wi-Fi (802.11b/g/n)
What's really weird is I don't see optical, coax, or hdmi audio in.
Just hdmi (for the video presumably) and a headphone in connection.
