UNISOC SC9863A vs Mediatek Helio G85

UNISOC SC9863A

The Unisoc SC9863A (formerly Spreadtrum) is an entry level octa core SoC with 8 ARM Cortex-A55 cores in two clusters. One performance cluster with up to 1.6 GHz and a efficiency cluster with up to 1.2 GHz. The SoC also integrates an LTE modem (TDD-LTE/FDD-LTE/TD-SCDMA/WCDMA/GGE), a PowerVR IMG8322 /GE8322 graphics card and 1080p video support.

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.
