Qualcomm Snapdragon 662 vs Mediatek Helio A20 MT6761D vs Qualcomm Snapdragon 636

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.

Mediatek Helio A20 MT6761D

The Mediatek Helio A20 MT6761D is an entry-level ARM SoC for smartphones and tablets (mainly Android-based) that was introduced in 2020. It integrates four ARM Cortex-A53 cores clocked at up to 1.8 GHz. It integrates a PowerVR GE6300 GPU clocked at up to 550 MHz. The integrated memory controller supports LPDDR4x (max. 4 GB at 1200 MHz). Furthermore, a LTE radio with Cat-4 DL (150 Mbps download) and Cat-6 UL (50 Mbps upload) and a 802.11 a/b/g/n/ac Wi-Fi 5 modem is integrated.

Compared to the similar named A22 MT6761, the MT6761D offers lower clocked CPU and GPU cores and a slower LTE modem, but is produced in the modern 12 versus 16nm process.

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).
