Mediatek MT6739 vs Mediatek MT8766B vs MediaTek MT8168

Mediatek MT6739

The MediaTek MT6739 is a 64-bit ARM-based SoC launched in 2017 primarily for small budget Android devices. The quad-core processor is based on the Cortex-A53 architecture and clocks up to 1.5 GHz. It integrates an LTE modem (Cat. 4 DL / Cat 5 UL) and a PowerVR GE8100 at 570 MHz (the predecessors used ARM Mali GPUs). Furthermore, the SoC integrates a 802.11 a/b/g/n Wi-Fi adapter and a video de- and encoder in hardware.

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).

MediaTek MT8168

The MediaTek MT8168 is an ARM based entry-level to mid-range SoC for (Android based) tablets. It offers four ARM Cortex-A53 processor cores (quad-core) that are clocked with up to 2 GHz. Furthermore, an ARM Mali-G52 MC1 (or MP1) graphics card, a LPDDR4x memory controller, Bluetooth and dual-band Wifi-5 802.11 b/g/n/ac are integrated in the SoC. The integrated camera ISP supports sensors with up to 13 MPix an Full HD videos at 60 fps.

The performance is situated in the entry level of 2020 and between a Snapdragon 429 and Snapdragon 632.
