Qualcomm Snapdragon 662 vs UNISOC T618 vs UNISOC T616

Qualcomm Snapdragon 662

The Qualcomm Snapdragon 662 is a lower mid-range ARM-based SoC largely found in 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.

UNISOC T618

The Unisoc Tiger T618 (former Spreadtrum) is an entry level octa core SoC with two fast ARM Cortex A75 cores at up to 2 GHz and six power efficient ARM Cortex A55 cores at up to 2 GHz. The SoC furthermore includes an LTE modem (TDD-LTE, FDD-LTE, TDSCDMA, WCDMA, CDMA, GSM), a LPDDR3-933 / LPDDR4x-1866 memory controller and an ARM Mali G52MP2 GPU and a tri core ISP. The chip is manufactured at TSMC in 12nm FinFET. AI acceleration is handled by a visual digital signal processor (VDSP) clocked at up to 936 MHz.

UNISOC T616

The Unisoc Tiger T616 (former Spreadtrum) is an entry level octa core SoC with two fast ARM Cortex A75 cores at up to 2 GHz and six power efficient ARM Cortex A55 cores at up to 1.8 GHz. The SoC furthermore includes an LTE modem (TDD-LTE, FDD-LTE, TDSCDMA, WCDMA, CDMA, GSM), a LPDDR4x 1866 MHz memory controller and an ARM Mali G57MP1 GPU (750 MHz max) and a dual core ISP (24 and 8 MPixel support). The chip is manufactured at TSMC in 12nm FinFET.
