PX30 Android Headunit Processor

The PX30 processor has found its way into the android headunit, There are always questions on these processing cores and the PX30 SoC is no different. We answer some of the more common PX30 questions to help you make an informed purchase of your android headunit.


PX30 Questions and Answers

Is the PX30 a good processor for an Android Head Unit?

No, the PX30 is a poor choice for an android head unit.

Can you call the PX30 a fast processor?

No, the PX30 is not a fast processor.

Which is better, the PX30 or the RK3326 for an Android car stereo?

PX30 and RK3326 perform the same in an android head unit.

Is the PX30 Processor a Quadcore?

Yes, the PX30 is a quadcore processor


Quadcore PX30

The PX30 is based on the RK3326 processor an made for low power, smart AI, VoIP and IoT devices. Nothing special, just a workhorse that would sit in a black box doing its work. Some how it made its way into an android headunit and has been powering them along.

Cores

The PX30 has four Cortex A35 cores of the ARMv8-A variety. It’s not very well positioned for the sales pitch when 8 cores beats 4 cores and quite often you see the PX30 android headunits with only 2Gb RAM. Considering 8 or 6 cores with 4Gb or 6Gb being the current norm, why would anyone consider the outdated PX30 when there are much better looking options?

More cores makes processing quicker, generally. Different generations of cores affect the processing power along with the clock speed of the cores. Unfortunately the PX30 is only clocked at 1.5Ghz so its not going to be the much faster clocked and cored later generations.

PX30 Block Diagram

All very impressive looking PX30 block diagram, but the quad cores, clocked at 1.5Ghz are aimed at very low power devices that are not designed to be heavy on the processing. The 32bit memory controller limits access to a maximum of 2Gb RAM, which for a modern system is very limiting.

RAM

The PX30 can address 2Gb RAM
Compatible RAM systems are DDR4-1600, DDR3 L-1600, LPDDR3-1600 or LPDDR2-1066

RK3326

The RockChip RK3326 is virtually identical to the PX30 processor. While they have some very subtle differences, when comparing the PX3 with the RK3326 performance they operate at the same level.

PX30 Quadcore

The PX30 android headunit SoC is a quadcore chip. Unfortunately the term ‘quadcore’ has left a bad impression on the buyers. This was after the 8227L faked android headunits that were also powered by a different quadcore processor.

Why?

Why buy an android headunit based on the PX30 SoC? Only the cost could be an answer. While being a big step up from the 8227L, it is way behind the much quicker UIS7862 or even the very common PX6 based units. The PX30 would be better placed in a VoIP box sat in an office managing telephone calls than being the powerhouse behind your in car entertainment and android apps.

Overall

The PX30 is not a good choice for an android headunit. This due to the very low level of processing power at a low clock rate. The addressable level of RAM is usually limited to 2Gb. Android headunits perform more fluidly and nicer to use when 4Gb RAM or more and 6 or more high speed cores are used. The PX30 android headunit will be disappointingly slow compare to modern standards.
