Qualcomm Snapdragon 430 (MSM8937) vs Samsung Exynos 850

Qualcomm Snapdragon 430 (MSM8937)

The Qualcomm Snapdragon 430 (SD430) is a lower mainstream SoC for (Android based) smartphones and tablets. Contrary to the Snapdragon 630, it is still manufactured in a 28-nm process and also consists of an octa-core CPU part with ARM Cortex-A53 cores. However, they are only clocked at up to 1.4 GHz. The integrated X6 LTE modem supports Cat. 4 with maximum transfer rates of 150 Mbps (downstream) and 75 Mbps (upstream). The SoC also includes an Adreno 505 GPU with support for Vulkan and OpenGL ES 3.1. WiFi 802.11ac and Bluetooth 4.1 are supported as well. The memory controller supports LPDDR3 clocked at 800 MHz (so probably dual-channel DDRL-1600). 

Samsung Exynos 850

The Samsung Exynos 850 is a System on a Chip (SoC) for entry level smartphones (Android based). It was announced in May 2020 and the first device with it is the Samsung Galaxy A21s. The chip integrates a processor with 8 small ARM Cortex-A55 cores that clock with up to 2 GHz (octa core).

The multi threaded performance is quite good thanks to 8 cores, the single threaded performance suffers a bit from the small A55 cores, although the clock rate of up to 2 GHz can help a bit.

Furthermore, the SoC integrates a LTE modem (Cat.7 2CA up to 300 MBit/s download, Cat.13 2CA 150 MBit/s upload), a Wi-fi 5 modem (802.11ac), LPPDDR4x memory controller, eMMC 5.1 flash memory controller and a video engine for FHD 60fps encoding and decoding (H.265, H.264, VP9).

It is manufactured in the modern 8nm LPP process at Samsung and should offer a good power efficiency and therefore it is also suited for small smartphones.
