That’s about all I know so far. Hisilicon mobile SoCs have not found their way in many handsets in the past, apart from Huawei smartphones. We’ll see if that one becomes more popular.

HiSilicon shows some smart design choices in this chip. It is clearly designed to be relatively cheap to manufacture (relatively limited chip die area) while still providing good performance for low/mid-range devices. In the past, HiSilicon has been using CPU cores with a relatively large die area such Cortex-A9 and Cortex-A15, which do not result in a particularly cheap or power-efficient chip. However, the Cortex-A53 is direct successor to the very power efficient and extremely small Cortex-A7 core, which means even with eight cores the chip will still be relatively small. Other companies are at an advanced stage of introduction… Read more »
