I’ve just discovered another dual core Rockchip SoC called RK3068, but it may not be new, as I can find some references as far back as September 2012. Amazingly, I can’t seem to find any announcement, and details are scarce. Very few products feature this chipset, but Risun D05, an Android mini PC, is one of them, so let’s have a closer look.
Risun D05 specifications based on Alibaba listing:
- SoC- Rockchip RK3068 dual core ARM Cortex A9 @ 1.6 GHz with dual core Mali-400 GPU
- System Memory – 1 GB DDR3
- Storage – 4 GB NAND Flash, with option for 8GB or 16GB, + micro SD card slot (Up to 32GB)
- Video Output – HDMI 1.4 male
- Video Codecs – MPEG 1, MPEG-2, MPEG 4,H.263, H.264, AVS, VC 1, RV, VP6 VP8, Sorenson Spark, MVC 1920x1080P 60FPS.
- Video Encoder – H.264,VP8,MVC(1080P)
- Audio Formats – MP1, MP2, MP3, WMA, WAV, OGG, OGA, APE, FLAC, AAC, M4A, 3GPP
- Connectivity – Wi-Fi 802.11 b/g/n + optional micro USB to Ethernet adapter.
- Power Supply – 5V/1A via Micro USB
- Dimensions – 81.6 x 28.5 x 8.5 mm
- Weight – 50g
The device runs Android 4.1. I found the device on Alibaba, and Risun is the only company selling RK3068 mini PCs for $30 to $50 (FOB price). Risun also has a website where they list D02 and D03 mini PCs, but there’s no information about D05 yet.
I found out about RK3068 on rockchip-linux IRC channel, as one developer posted the picture below comparing MK806 (RK3066) with an RK3068 evaluation board from JDS, a Japanese company.
RK3068 is much smaller than RK3066, and allows for smaller HDMI TV stick designs. Both SoCs feature a dual core ARM Cortex A9 processor @ 1.6GHz, and are manufactured using 40nm process technology, but RK3068 apparently comes with a Mali-400 MP2 GPU, whereas RK3066 comes with Mali-400 MP4.
An article from PCOnline (in Chinese) seems to imply RK3068 directly supports 3G modules. Unedited Google translation:
Rockchip RK3068 CPU specifications on many parameters and we have been very familiar with RK3066 dual core solution is very close, they are also dual-core A9 1.6GHz clocked CPU, also support DDR3 memory, support 1080P HD video formats hardware decoding. However, RK3068 scheme can support 3G module, call the Internet.
That’s about all I know for now.
