Qualcomm Snapdragon 665 vs Qualcomm Snapdragon 835 (8998)

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 835 (8998)

The Qualcomm Snapdragon 835 Mobile Platform (MSM8998) is a high-end SoC for smartphones (mostly Android based) that was released early 2017. Its one of the first processors that is manufactured in 10 nm (LPE FinFET at Samsung). The SD835 is the successor to the Snapdragon 821.

It integrates 4x Kryo 280 at 2.45 GHz (max) for performance and 4x Kryo 280 at 1.9 GHz (max) for efficiency. Furthermore offers an X16 LTE modem, 802.11a/b/g/n/ac/ad WiFi, a dual-channel 32-Bit 1866 MHz LPDDR4x memory controller, an UFS 2.1 controller, Hexagon 682 DSP, Spectra 180 Image Seonsor Prozessor, Bluetooth 5.0, GPS, GLONASS, Baeidou, Galileo Satellite Support.
