Unisoc T7255 (T616) vs Mediatek Helio G80 vs Mediatek Helio P90

Unisoc T7255 (T616)

The Unisoc T7255 (formerly Unisoc T616) 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 1.8 GHz. The SoC further includes an LTE modem (TDD-LTE, FDD-LTE, TDSCDMA, WCDMA, CDMA, GSM), an LPDDR4x-1866 memory controller and an ARM Mali G57 MP1 GPU (750 MHz max) and a dual core ISP (24 and 8 MPixel support). The chip is manufactured by TSMC on a 12nm FinFET process.

Mediatek Helio G80

The Mediatek Helio G80 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 950 MHz. 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.

Mediatek Helio P90

The Mediatek Helio P90 is an upper mainstream ARM SoC for smartphones (mainly Android based) that was introduced in 2019. It is manufactured in a 12 nm FinFET (12FFC) process and is equipped with 2x big ARM Cortex-A75 cores (2.2 GHz max.) and 6x small and power efficient ARM Cortex-A55 cores (2 GHz max.) in two clusters (bigLITTLE). The processor also integrates a Cat-12 (600 Mbps DL) / Cat-13 (150 Mbps UL) LTE Modem (4G), a PowerVR GM 9446 GPU, and ISP for 64 MP photos and 4K videorecording, and a AI Processing Unit with a theoretical performance of 1165 Giga-Multiply-Adds per second. The memory controller on the die supports dual-channel LPDDR4x-1866 (8 GB max.) and flash memory can be connected by UFS 2.1.

The CPU performance should be slightly below a Snapdragon 730 (e.g. in the Reno2 Z in our benchmarks) and therefore in the upper middle-class of 2019 smartphones.
