[Update May 2017: Rockchip has renamed RK1108 to RV1108.]
Rockchip has introduced RV1108 ARM Cortex A7 SoC with a 600 MHz DSP targeting visual communication, consumer electronics, automotive DVR, and security applications thanks to its 8-channel I2S audio codec and 1440p H.264 video encoder and decoder.

There’s no much more information at this stage, and beside the evaluation board shown above, I could not find devices based on Rockchip RV1108 processor yet. Some code has been pushed to GeekboxZone Linux kernel repo in Github.
The company also unveiled Rockchip PX5 octa-core Cortex A53 processor for automotive applications with support for ADAS algorithms, and 4K60 video decoding, but there’s even less information than for RV1108 so far.
