The recently announced Redmi 6A by Xiaomi in China introduced the world to a MediaTek Helio A22 chipset. The chipset made by the Taiwanese silicon maker is mid-range chipset and is part of the company’s new goal of bringing premium features down to more affordable offerings. The details revealed by MediaTek about the chipset certainly reveals so.

The Helio A22 is a quad-core chipset with four ARM Cortex-A53 cores with a max frequency of 2GHz. That is combined with a IMG PowerVR GE-class GPU. The chipset supports both LPDDR4X and LPDDR3 RAM along with support for eMMC 5.1 storage type. The A53 cores are efficiency cores built on ARM’s v8-A architecture and can be paired in a big.LITTLE configuration with other A53 cores.

According to MediaTek, the Helio A22 is 30 percent faster in computing and 72 percent better in graphics. The chipset uses MediaTek’s CorePilot technology  which provides intelligent CPU scheduling based on power intake, thermal management. The technology homebrewed by MediaTek assigns the workload to different CPU cores efficiently.

The chipset also comes with a ultra-low power sensor hub for apps that require always-on sensor readings, such as a pedometer or a language processor. These apps will engage the sensor hub instead of taxing the CPU, thereby saving more power.

Furthermore, the Helio A22 brings Edge AI onboard, although in a rudimentary form. The capabilities will allow for FaceID, smart photo album, and single and dual camera bokeh effects in smartphones. However, MediaTek’s NeuroPilot platform gives developers the ecosystem to leverage the AI capabilties of the chip. The platform is fully compliant with Android Neural Networks API and comes with common AI frameworks.

The Helio A22 uses MediaTek’s WorldMode 4G LTE modem that provides 4G dual SIM support with dual VoLTE/ViLTE. There’s also the company’s TAS 2.0 smart antenna tech that optimises the signal using multiple cameras.

Over its previous generation, the MediaTek Helio A22 now includes multi-GNSS options for multiple GPS standards. It is also 24 percent more power efficient thanks to the onboard sensor hub. There’s also support for Bluetooth 5 for twice the speed and four times the range.
