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.
The 1.5 GHz MediaTek MT6735 is a 64-bit ARM-based SoC launched in 2014 primarily for small budget to mainstream Android devices. The quad-core processor is manufactured in 28 nm and is based on the Cortex-A53 architecture. It integrates a cat.4 LTE modem with CDMA2000 and an ARM Mali-720 GPU capable of decoding and encoding videos of up to 1080p30. Compared to the MT6732, the MT6735 utilizes a slower graphics unit.
Processor
The Cortex-A53 is the successor to the popular Cortex-A7 design. In addition to the jump from 32-bit to 64-bit architecture (ARMv8 ISA) to address more than 4 GB of memory, the new design offers better branch prediction and higher performance-to-power ratio that rivals the Cortex-A9. The four cores of the MT6732 are clocked at up to 1.5 GHz and sits roughly in between the Qualcomm Snapdragon 610 (4x Cortex-A53 at 1.7 GHz) and Snapdragon 410 (4x Cortex-A53 at 1.2 to 1.4 GHz). The power-efficient processor is fit for common tasks like browsing and running light applications.
Graphics
The integrated single-core Mali-T720 is an entry-level GPU clocked at up to 600 MHz (450 MHz likely). Most Android games will play at acceptable frame rates on medium resolutions and quality.
Features
The MT6732 SoC integrates a memory controller (32-bit LPDDR3, 6.4 GB/s), multiple radios (WLAN, Bluetooth, GPS), and a cellular modem (GSM, UMTS, GPRS, HSPA+, HSUPA, TD-SCDMA, EVDO, and LTE Cat 4). Its integrated video engine allows for 1080p playback at 30 FPS. Cameras are supported up to 13 MP.
