Mediatek MT8165 vs Mediatek MT8766B

Mediatek MT8165

The MediaTek MT8165 is a 64-bit ARM-based SoC for Android devices launched in 2014. The quad-core processor is manufactured in 28 nm and based on the Cortex-A53 architecture. In addition to the CPU core, it integrates an ARM Mali-760 MP2 GPU and a LPDDR3 memory controller (32-bit, 800 MHz, 6.4 GB/s).

Processor

The Cortex-A53 is the successor to the popular Cortex-A7 design. In addition to the jump from 32-bit to 64-bit architecture (ARMv8 ISA) to address more than 4 GB of memory, the new design offers better branch prediction and higher performance-to-power ratio that rivals the Cortex-A9. The four cores of the MT8165 are clocked at up to 1.5 GHz and sits roughly in between the Qualcomm Snapdragon 610 (4x Cortex-A53 at 1.7 GHz) and Snapdragon 410 (4x Cortex-A53 at 1.2 to 1.4 GHz). The power-efficient processor is fit for common tasks like browsing and running light applications.

Graphics

The integrated dual-core Mali-T760 MP2 is a mid-range GPU clocked at up to 500 MHz. Most Android games will run at acceptable frame rates on medium resolutions and quality.

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).
