UNISOC T750 vs Qualcomm Snapdragon 665

UNISOC T750

The Unisoc T750 (Tanggula, former Spreadtrum) is a mid range SoC for Android based smartphones and tablets. It integrates an octa-core CPU with two clusters. Two fast ARM Cortex-A76 cores clocked at up to 2 GHz and six small ARM-Cortex-A55 cores at again up to 1.8 GHz for efficiency. The faster T760 SoC offers two more A76 cores, a faster GPU and a faster memory controller.

The integrated memory controller supports LPDDR4X with up to 1866 MHz. The integrated ISP supports two main cameras (up to 64 MPix). The integrated graphics card is an ARM Mali-G57 MC2 (2 cores) at up to 680 MHz. The integrated modem supports Wi-Fi 5 WLAN, 5G (TDD+FDD CA Sub-6GHz), and Cat15DL / Cat18 UL LTE.

The chip is manufactured in the modern 6nm process.

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.
