Qualcomm Snapdragon 665 vs Qualcomm Snapdragon 730 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.

Qualcomm Snapdragon 730

The Qualcomm Snapdragon 730 (SD730 Mobile Platform) is a fast mid-range ARM-based SoC largely found on Android tablets and smartphones. It integrates eight cores (octa-core) divided into two clusters. A fast performance cluster contains two ARM Cortex-A76 cores clocked at up to 2.2 GHz and a power efficiency cluster with six small ARM Cortex-A55 cores at up to 1.8 GHz. Depending on the workload only single clusters or all cores can run at different clock speeds.

The chip includes a range of other features like a fast X15 LTE radio (800 Mbits Cat 15 download, 150 Mbps Cat 13 upload), one of the first Wi-Fi 6 wireless radios (802.11ax), satellite positioning (GPS, QZSS, GLONASS, SBAS, Beidou, Galileo), USB-C 3.1, Spectra 350 ISP, Hexagon 688 DSP, H.265 4K30 video en- and decode, an LPDDR4X-3733 dual-channel memory controller and a Adreno 618 Grafikkarte.

The Snapdragon 730 is manufactured in the modern 8 nm process at Samsung.

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).
