- CC1800 processor (ARM926 400MHz).
- 320x240 LCD, slightly larger than the A320 one.
- 64MB RAM.
- 2.4 GHz communication module. This is a true radio device and not just a keyboard hack. Enables multiplayer and custom peripherals.
- USB OTG port, which allows connecting USB devices, but you'll need external +5V power (i.e. a powered hub).
I would say that the CC1800 CPU core belongs in the same class than the JZ4732 in the A320, however, being an ARM architecture has the advantage of the existing assembly optimized emulation cores. I bet that the VPU will allow a sizeable boost in performance by offloading the color conversion work from the SDL code.
64MB vs. 32MB in the A320 are a big advantage too.
