Mediatek Helio G25 vs UNISOC SC9863A

Mediatek Helio G25

The Mediatek Helio G25 is an entry level ARM SoC for smartphones (mainly Android based) that was introduced in late 2020. It is manufactured in a 12 nm FinFET process and is equipped with 8 ARM Cortex-A53 CPU cores divided in two clusters. A performance cluster with 4 cores clocked at up to 2 GHz and a efficiency cluster clocked at up to 1.5 GHz. Compared to the similar Helio A25, the G25 clocks the GPU (+50 MHz) and the CPU cores higher (+200 MHz).

Furthermore, the SoC integrates a LTE Cat.4 modem, a LPDDR3-933 / LPDDR4-1200 / LPDDR4x-1600 memory controller, a IMG PowerVR GE8320 graphics card and a 1080p30 video de- and encoder (H.265 decoding, H.264 encoding).

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.
