RK3399 vs PX6

RK3399 processor was faster than the Android headunits, and the PX6 processor was also found in similarly specified Android headunits. Usually, 4 GB RAM and 64 GB ROM are modern SoC devices ideally suited to running Android.

No contest

There is no contest between the PX6 and the RK3399 because they can be considered exactly the same.

Both have the same dual-core Cortex A72 processors and a quad-core Cortex A53 processor making them a ‘hexacore’ processor – but often incorrectly described as ‘octa-core’ in the sales pitch (8 cores sounds better than 6 cores), which is just misleading.


As far as everything goes, the RK3399 is a bit of a mouthful, and PX6 is much easier to remember in the minds of headunit buying customers.
