MT8768 Processor

8768 or MTK8768 is an MCU processing unit for running Android made my MediaTek, a Taiwan based fabless chip company. A big player in processors for android based devices and MediaTek chips are used by many different manufacturers to build their own technology around it.

MT8768T

The MT8768 is a modern processor with its debut in 2020.

Cores

There are 8 cores in the MT8768 which makes it an Octa-Core processor. These 8 cores boost processing power without the need for huge increases of clock speed.

All 8 cores are based on the ARM Cortex-A53 MPCore with 4 having the potential to be clocked at 2.3GHz while the other 4 ARM Cortex-A53 MPCore processing cores are clocked at 1.8Ghz.

This 1:1 split of the clock rates is to provide a granular step in performance by bring on the extra clock speed when needed. This is balanced with the lower clock speed and directly the lower power consumption of the slower cores. A balance of performance and power saving can be struck by managing these 8 cores in software.

While a battery device like a phone or tablet would benefit from this power saving feature, it is not relevant to the android headunit. But many mass produced phone and tablet processors find their way in to the android headunits. It is cheaper to re-purpose an existing phone chip than produce a new design for the headunits.

Tablets

The MT8768T was used to power the Samsung Galaxy Tab A7 10.4 where it was called by its marketing name: Helio P22T. With RAM being equal, an android headunit with the MT8768T would behave in response top taps, apps to load and boot time just like the Samsung Galaxy Tab it was originally fitted to.

It would behave quite acceptably, suitable for a Samsung in 2020, and many miles away from the quad cores that are often found in the android headunits.

RAM

Memory type can be of LPDDR3 or LPDDR4x. Both types are compatible with the 8768 but the decision is usually financial and the slower, yet cheaper DDR3 is often employed.

The 8767 is usually coupled to 4Gb RAM in 2020 but if there is an option for more, 6Gb or 8Gb would be better for future app support.

Graphics

The graphics capabilities for the Helio P22T (Mediatek MT8768T) is the IMG PowerVR GE8320-class graphics processor. The GE8320 class graphics processing is ideal for an android headunit and acceptable for mid to low end phones and tablets. The 3D capability is a key feature in phone and tablets to enable the modern games. An android headunit does not have this need for speedy 3D graphics, so a slower, yet cheaper graphics subsystem is the accepted norm in a headunit.

Suitability for an Android Headunit

Is the Helio P22T/MT8768T a good processor for an android head unit?
Yes, the MediaTek 8768 is a modern, quick processor designed for running android. It will perform well in an android headunit. Coupled to 6Gb or 8Gb RAM it will stay useful for the years to come.

On a scale of the year 2014 for an 8227L quadore, the MT8768T is in another dimension and a much better choice of processor MCU for android.
