Samsung Exynos 7884B vs Qualcomm Snapdragon 665

Samsung Exynos 7884B

The Samsung Exynos 7884B (also called Exynos 7 Series) is a upper mid-range system-on-a-chip (SoC) for smartphones and tablets. It integrates two big ARM Cortex-A73 cores clocked at up to 1.56 GHz. Furthermore, there are six power efficient Cortex-A53 cores at up to 1.35 GHz, an ARM Mali-G71 MP2 GPU and a LPDDR4x memory controller. Compared to the faster Exynos 7885, the CPU cores of the 7884B are clocked clearly lower. Furthermore, the integrated LTE modem is also slower (150 / 50 Mbit download / upload). 802.11ac WiFi, Bluetooth 5.0 and FM Radio are also in the chip. It is manufactured in 14nm FinFET at Samsung and therefore a rather power efficient SoC.

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.
