Mediatek Helio G81 Ultra

Mediatek Helio G81 Ultra

The Mediatek Helio G81 Ultra is a mainstream ARM SoC for smartphones (mainly Android based) that was introduced in 2020. It is manufactured in a 12 nm FinFET process and integrates 8 CPU cores. Two fast ARM Cortex-A75 cores with up to 2 GHz for performance tasks and six small ARM Cortex-A55 with up to 2 GHz for efficiency. All eight cores can be used together thanks to Heterogeneous Multi-Processing support. The integrated GPU is a ARM Mali-G52 MC2 (MP2) with two clusters at up to 950 MHz. The SoC also integrates the HyperEngine that handles a dynamic management of CPU, GPU and memory.

Compared to the old Helio G80, the G81 offers support for 120Hz displays.

The SoC integrates furthermore a LTE radio with Cat-7 (download) / Cat-13 (upload) support, Wifi 5 (ac), Bluetooth 5.0, LPDDR4x 1800 MHz and eMMC 5.1 storage.
