Mediatek Helio G90T vs Mediatek Helio G81

Mediatek Helio G90T

The Mediatek Helio G90T is an upper mainstream ARM SoC for smartphones (mainly Android based) that was introduced in 2019. It is manufactured in a 12 nm FinFET process and is equipped with 2x big ARM Cortex-A76 cores with up to 2.05 GHz and 6x small and power efficient ARM Cortex-A55 cores (max. 2 GHz) in two clusters (bigLITTLE). The chip also integrates a ARM Mali-G76 3EEMC4 (should be a MP4 - four cluster variant) clcoked at 800 MHz. Furthermore, the integrated LTE modem supports Cat-12 600 Mbps download and Cat-13 150 Mbps upload speeds. Wi-Fi 5 is also integrated (a/b/g/n/ac). The memory controller supports LPDDR3 and LPDDR4x with up to 2,133 MHz with up to 10 GB capacity.

Mediatek Helio G81

The Mediatek Helio G81 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 1.7 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.
