Qualcomm Snapdragon 665 vs Mediatek MT6753

Qualcomm Snapdragon 665

The Qualcomm Snapdragon 665 (SM6125) is a fast mid-range ARM-based SoC largely found on Android tablets and smartphones. It features 8 Kryo 260 cores (custom design, 64-Bit capable) that are divided in two clusters. A fast cluster of four cores with up to 2 GHz (Kryo 260 Gold - Cortex-A73 derivate) and a power saving efficiency cluster with up to 1.8 GHz (Kryo 260 Silver - Cortex A53 derivate). Both clusters can also be used together.

In addition to the 8 CPU cores, the SoC integrates a mid range Adreno 610 GPU with a LPDDR4 memory controller (dual-channel)  and supports Wi-Fi (802.11ac + MIMO, max. 867 Mbps), Bluetooth 5, and LTE (X12 LTE modem with up to 600 Mbps download and 150 Mbps upload).

Power Consumption

Thanks to the new 11 nm LPP process, the energy efficiency should be quite good.

Mediatek MT6753

The ARM-based Mediatek MT6753 SoC (System on a Chip) is a mid-range mobile processor announced in mid 2015 for smartphones and tablets (mostly Android based). It integrates 8 ARM Cortex-A53 cores consisting of 4 high-performance cores clocked at up to 1.5 GHz plus 4 low-power cores. Furthermore, the SoC integrates a Cat. 4 LTE radio and an ARM Mali-T720 MP4 GPU clocked at 600 MHz with 802.11n WiFi and Bluetooth connectivity.

The Cortex-A53 is the successor to the Cortex-A7 and introduces 64-Bit support (ARMv8-ISA). Its performance-per-Watt is significantly higher and is even slightly ahead of the old Cortex-A9. If utilizing all 8 of its cores, the Cortex-A53 can rival competing mobile processes in the high-end class range. However, no practical software has been specifically coded to use all 8 cores at such high performance levels.

The MT6753 is manufactured in 28nm and should be suited for smaller smartphones.
