Qualcomm Snapdragon 630 vs Samsung Exynos 850 vs Qualcomm Snapdragon 435

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.

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.

Qualcomm Snapdragon 435

The Qualcomm Snapdragon 435 (SD435) 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 X9 LTE modem supports Cat. 4 with maximum transfer rates of 300 Mbps (downstream) and 100 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). The main difference to the Snapdragon 430 is the faster LTE modem.
