Samsung Exynos 7870 Octa vs Qualcomm Snapdragon 625 vs Qualcomm Snapdragon 630

Samsung Exynos 7870 Octa

The Samsung Exynos 7 Octa is a 64-bit SoC for mainstream smartphones and tablets (usually Android based). It was announced in February 2016 and integrates eight Cortex-A53 cores, which are manufactured in a modern 14-nm process. Compared to the previous 28-nm-SoCs, the performance was increased and the power consumption is 30 % lower according to Samsung. The integrated LZE Cat.6 modem reaches transfer rates of up to 300 Mbps (downstream) and 50 Mbps (upstream). The dual-channel memory controller supports LPDDR3-1866 RAM.

The graphics adapter ARM Mali-T830 MP2 (core clock of 700 MHz according to Wikipedia) is also used in combination with the HiSilicon Kirin 650 SoC. Besides OpenGL ES 3.2, it also supports OpenCL 1.2 as well as DirectX 11 (FL 9_3). The performance is sufficient for common Android games from 2016 at medium details.

Qualcomm Snapdragon 625

The Qualcomm Snapdragon 625 (SD625) is a mid-range octa-core SoC with eight ARM Cortex-A53 cpu cores at up to 2 GHz, an Adreno 506 GPU, a DDR3L-1866 memory controller and a X9 LTE (Cat 7, 4G+, 300 Mbps down, 150 Mbps up) modem. Furthermore, the chip supports 802.11ac WiFi and Bluetooth 4.1. It is manufactured in 14nm FinFet. The processor performance should be similar to a HiSilicon Kirin 650, which also offers 8 Cortex A53 cores at up to 2 GHz. However, due to the modern manufacturing process, power consumption and throttling should be better with the Snapdragon 625.

Qualcomm Snapdragon 630

The Qualcomm Snapdragon 630 (SDM630) is a mid-range octa-core SoC with eight ARM Cortex-A53 CPU cores at up to 2.2 GHz, an Adreno 508 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. The processor performance should similar to the older Snapdragon 626 which offers similar clock speeds. Compared to the 626, the 630 however supports faster memory and offers faster LTE, Wifi and Bluetooth standards.
