Rockchip PX3 and PX4 Processors Are Designed for Automotive Infotainment & Dashboards

Rockchip PX2 processor, similar to Rockchip RK3066 but targeting industrial and automotive applications, was launched in 2014. Rockchip now has at least two new member in their PX family with PX3 and PX4 specifically designed for automotive infotainment and car dashboards thanks to dual display support, at least according to one article on Elezine.

Rockchip PX3 is definitely confirmed with its own page on Rockchip website, and features a quad core Cortex A9 @ 1.4 GHz with a Mali-400MP4 GPU, and while there’s no info about PX4 yet on the company website, the SoC should come with a quad core Cortex A53 processor @ 1.3 GHz with a Mali-T722 GPU, as well as HDMI 2.0 video output, and H.265 video decoding.

The article also lists 7 key function of Rockchip solutions:

1. “Quick startup and fast revert track”
2. Navigation system with free updates
3. HD video recording (car DVR)
4. Advanced ADAS algorithm to achieve the trajectory, distance between vehicles, license plate recognition, collision avoidance and other functions
5. Dual screen support
6. Mobile Internet control
7. Support for 1080p H.264 decoding and voice recognition input

I could not find system or demo with dual display system with PX3 (dashboard + infotainment), but did find a video of a double DIN car stereo based on Rockchip PX3 processor and running Android 4.4.

Auto Pumpkin sells several PX3 based stereo for various car models on their website for $250 and up. Cold boot time is rather standard however (25 to 30 seconds). I found about PX3 processor via one IloveRockchip tweet boasting about a “large screen in-vehicle navigation for Dongfeng Kadjar”, but I could not find any details, as maybe the news is only reported in Chinese media.
