Qualcomm Snapdragon 665 vs Mediatek Helio P23 MT6763T vs Qualcomm Snapdragon 636

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.

Mediatek Helio P23 MT6763T

The Mediatek Helio P23 MT6763T is a mainstream ARM SoC for smartphones (mainly Android based) that was introduced in 2017. It is manufactured in a 16 nm FinFET+ process and is equipped with 8 ARM Cortex-A53 CPU cores. The cores are divided in two clusters, a performance cluster clocked at up to 2.3 GHz (2.5 GHz for a single core only) and a power efficiency cluster clocked at up to 1.65 GHz. The chip also includes an LTE modem (Cat. 7 DL / Cat. 13 UL with Dual-SIM support) and a 802.11a/b/g/n WiFi modem. The integrated ARM Mali-G71 MP2  GPU is clocked at up to 770 MHz and has two cluster (from 32). The integrated memory controller supports DDR4x (Dual-Channel?) at 1500 MHz and LPDDR3 (Single Channel only) at 933 MHz. The video engine supports H.264 de- and encoding but only decoding (playback) of H.265/HEVC.

Qualcomm Snapdragon 636

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).
