The A22 is built around a quad-core Cortex-A53 CPU cluster, which in this latest SoC will be clocking at up to 2GHz. Those CPU cores will in turn be paired up with an Imagination PowerVR GE8320 GPU, a single cluster GPU design released by Imagination last year. Overall this is relatively similar to the MT6739, following the same CPU and GPU architectures but with more powerful configurations chosen. However beyond that, the A22 immediately starts setting itself apart from the MT6739 thanks to its manufacturing process: it is the first entry-level MediaTek SoC to be produced on a sub-28nm process, with MediaTek specifically using TSMC’s 12nm process, the same used for the Helio P60.
MediaTek isn’t especially promoting the use of TSMC’s 12nm process, but the choice is none the less an important one. The most immediate benefit to users are the power savings MediaTek will see from the newer process; the company expects to do very well here thanks to the process and what they feel is a market-leading power & task management technology in the form of the latest CorePilot. As for OEMs, the benefit of the smaller 12nm is just that: it’s smaller. And since die size is king in the entry-level market, it means that the A22 stands to be a very competitive chip indeed, maximizing the number of chips produced per wafer and keeping SoC costs to a minimum.
Overall however, MediaTek’s strongest focus on the SoC isn’t on its core configuration of performance; as should be obvious from the core specifications of the phone, the SoC isn’t going to burn up the charts in terms of performance. Rather the company is trying to differentiate itself and the A22 from a feature standpoint, particularly in the areas of camera support and LTE performance.
It is a great chip.
