A quick google found
http://wenku.baidu.com/view/aef3b509844769eae009ed23.html

which as expected shows a lot of similarity with the I/O of A10.

Core: 400MHz/533MHz ARM926EJ-S 
Memory: Up to 1GB SDR/DDR/DDR2/LPDDR SDRAM

Accelerated 2D graphics. No 3D graphics engine.
Accelerated HD codecs engine

I/O capabilities very similar to A10, but with slight differences.
- No built-in HDMI. External transmitter needed for LCD->HDMI.
- Apparently have a built-in smartcard interface
