Unisoc T7255 (T616) vs Qualcomm Snapdragon 680 4G
Unisoc T7255 (T616)
► remove from comparison
The Unisoc T7255 (formerly Unisoc T616) 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 further includes an LTE modem (TDD-LTE, FDD-LTE, TDSCDMA, WCDMA, CDMA, GSM), an LPDDR4x-1866 memory controller and an ARM Mali G57 MP1 GPU (750 MHz max) and a dual core ISP (24 and 8 MPixel support). The chip is manufactured by TSMC on a 12nm FinFET process.
Qualcomm Snapdragon 680 4G
► remove from comparison
The Qualcomm Snapdragon 680 (SD680, SM6225) is a mid-range ARM-based SoC largely found on Android tablets and smartphones. It features 8 Kryo 265 cores (custom design, 64-Bit capable) that are divided in two clusters. A fast cluster of four cores with up to 2.4 GHz (Kryo 265 Gold - Cortex-A73 derivate) and a power saving efficiency cluster with up to 1.8 GHz (Kryo 265 Silver - Cortex A53 derivate). Both clusters can also be used together. Compared to the older Snapdragon 665, the clock speeds are higher.
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 (X11 LTE modem with up to 390 Mbps download).
The SoC is produced in 6nm (compared to the older 11nm LPP process of the similar Snapdragon 665).
