【A83T】

This is the fourth Allwinner SoC which uses Power VR instead of MALI for GPU. See also SoCs A31, A31s and A80.

The H8 and R58 are nearly identical variants of the A83T.

Overview

A product verification board was created and several boards were sent to developers that applied for them. That board came with buildoot and Linux 3.4. There was no GUI in that image.
