Samsung Exynos 9611 vs Qualcomm Snapdragon 665 vs Qualcomm Snapdragon 636

Samsung Exynos 9611

The Samsung Exynos 9611 (or Exynos 7 Series 9611) is a mid-range SoC for Android based smartphones and tablets. It integrates 8 processor cores in two clusters (bigLITTLE concept). Four ARM Cortex A73 cores at up to 2.3 GHz for demanding tasks and four ARM Cortex A53 at up to 1.7 GHz for power efficiency. Compared to the older Exynos 9610, the 9611 supports higher resolutions for the rear faced camera.

The integrated LTE modem supports 4G at up to 600 Mbps download and 150 Mbps upload. Furthermore, 802.11ac WiFi and Bluetooth 5.0 are also integrated in the chip.

The on-board ARM Mali-G72 MP3 graphics card offers three clusters and support for Vulkan, DirectX 12 and OpenGL ES 3.2.

The Exynos 9611 is manufactured in the modern 10nm FinFET process and therefore relatively power efficient and also suited for smaller smartphones.

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 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).
