UNISOC T618 vs Mediatek Helio G85

UNISOC T618

The Unisoc Tiger T618 (former Spreadtrum) is an entry level octa core SoC with two fast ARM Cortex A75 cores at up to 2 GHz and six power efficient ARM Cortex A55 cores at up to 2 GHz. The SoC furthermore includes an LTE modem (TDD-LTE, FDD-LTE, TDSCDMA, WCDMA, CDMA, GSM), a LPDDR3-933 / LPDDR4x-1866 memory controller and an ARM Mali G52MP2 GPU and a tri core ISP. The chip is manufactured at TSMC in 12nm FinFET. AI acceleration is handled by a visual digital signal processor (VDSP) clocked at up to 936 MHz.

Mediatek Helio G85

The Mediatek Helio G85 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 1.8 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 1000 MHz (up from 950 MHz from the otherwise similar Helio G80). The SoC also integrates the HyperEngine that handles a dynamic management of CPU, GPU and memory.

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.
