Qualcomm Snapdragon 665 vs HiSilicon Kirin 710A

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.

HiSilicon Kirin 710A

The HiSilicon Kirin 710A is a ARM-based mid-range Octa-Core-SoC for Android based smartphones and tablets. It is based on the Kirin 710, but manufactured in 14nm FinFET at SMIC (China) versus the TSMC in 12nm. It was announced mid 2020 and contains 8 processor cores (4x Cortex-A73 at up to 2 GHz, 4x Cortex-A53 at up to 1.7 GHz, BigLITTLE), an ARM Mali G51 MP4, a dual-channel LPDDR4 memory controller and a LTE radio (600 Mbps down, 150 Mbps up). Therefore, the CPU part is similar to the Kirin 960 and 970 (both higher clocked), but the graphics card is a lot slower.
