Mediatek Helio G85 vs Mediatek MT8766B

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.

Mediatek MT8766B

The Mediatek MT8766B is an entry-level ARM SoC for smartphones and tablets (mainly Android-based) that was introduced in 2020. It integrates four ARM Cortex-A53 cores clocked at up to 2 GHz. and a PowerVR GE6300 GPU. It looks very similar to the older Helio A20 (-200 MHz CPU core clock).

The integrated memory controller supports LPDDR4x. Furthermore, a LTE radio with Cat-4 DL (150 Mbps download) and Cat-5 UL (75 Mbps upload) and a 802.11 a/b/g/n/ac Wi-Fi 5 modem is integrated.

The SoC should be produced in the same 12nm process as the Helio A20 (most likely the same chip).
