I. RK3368H-  high performance-cost ratio 8-core 64-bit solution

RK3368H is an upgraded version of RK3368, which has better performance and is more cost effective. Internal process of RK3368H is optimized; internal modules such as HDMI and Ethernet are reduced to improve bus efficiency. In terms of hardware, PINTOPIN is maintained with RK3368, and formerly designed hardware can be directly mounted to use. RK3368H supports Android 7.1, runs a higher score (as high as 48000 in antutu) and chip performance is given to full play. Its technical advantages are as follows:

1. 64-bit big.little architecture, Octa-core Cortex-A53, and frequency is up to 1.5GHz;
2. GPU is PowerVR SGX6110;
3. Support H.264 H.265 video decoding
4. Support light office OS such as Remix,Phoenix and Light Biz OS
