The Qualcomm Snapdragon 636 (SDM636) is a mid-range octa-core SoC with eight custom Kryo 260 cores at up to 1.8 GHz, an Adreno 509 GPU, a LPDDR4-2666 memory controller (1333 MHz) and a X12 LTE (Cat 12/13, 300 Mbps down, 150 Mbps up) modem. Furthermore, the chip supports 802.11ac WiFi and Bluetooth 5.0. It is manufactured in 14nm FinFet. Qualcomm states a 40% faster performance compared to the old Snapdragon 630 (8x ARM Cortex-A53).
The Unisoc Tiger T619 (former Spreadtrum) is an entry level octa core SoC with two fast ARM Cortex A75 cores at up to 2.2 GHz and six power efficient ARM Cortex A55 cores at up to 1.8 or 2 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 (850 MHz max) and a dual core ISP (24 and 8 MPixel support). The chip is manufactured at TSMC in 12nm FinFET.
Compared to the T616, the T619 offers 200 MHz higher clocked A75 cores and a 100 MHz higher clocked GPU.
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.
