Samsung Exynos W920 vs MediaTek MT8188J vs MediaTek Dimensity 8020

Samsung Exynos W920

The Samsung Exynos W920 is a dual-core ARM based SoC for IoT (Internet of Things) devices like smartwatches. It was announced in 2021 and integrates two ARM Cortex A55 cores clocked at 1.18 GHz. It is manufactured in the modern 5nm process. In addition to the CPU cores, the chip also integrates a ARM Mali-G68 MP2 GPU, Cat.4 (DL) / Cat.5 (UL) LTE modem, 1080p HEVC/H.264/VP8 video engine and a LPDDR4 memory controller.

MediaTek MT8188J

The MediaTek MT8188J is a mid-range ARM SoC (System-on-a-Chip) introduced in the first quarter of 2023, primarily used in Android-based tablets. It is manufactured using a 12-nanometer process and features a total of eight CPU cores (Octa-Core). These consist of two fast Cortex-A78 cores and 6 Cortex-A55 cores that work together in a big.LITTLE configuration.

The A78 cores of the MediaTek MT8188J can clock at speeds of up to 2.2 GHz, while the A55 cores can reach speeds of up to 2 GHz (going down to 500 MHz). For graphics processing, it employs an ARM Mali-G57 MP2 GPU. Additionally, it includes a video decoder with support for H.264 and H.265.

In addition to the CPU and GPU, the chip integrates an LPDDR4 memory controller, capable of supporting up to 8 GB of RAM. The SoC also includes a modem for WiFi 6, Bluetooth 5.3, and LTE up to Cat.7.

MediaTek Dimensity 8020

The MediaTek Dimensity 8020 is a ARM-based System-on-a-Chip (SoC) similar to the older Dimensity 1100. It was specifically designed for use in Android smartphones and falls into the mid-range category in terms of performance. It supports all current mobile network standards, including 5G with 2CC-CA (200MHz) and FDD+TDD.

The CPU consists of a total of eight cores divided into two clusters. One cluster has four ARM Cortex-A78 performance cores with speeds of up to 2.6 GHz, while the other cluster has four ARM Cortex-A55 power-efficient cores with speeds of up to 2.0 GHz. LPDDR4 RAM can be used as the memory, and it supports UFS 3.1 as the internal storage.

In terms of connectivity, it offers Dual-5G support, as well as Wi-Fi 6 and Bluetooth 5.2.

The integrated graphics unit, ARM Mali-G77 MC9, can power displays with a resolution of up to 2560 x 1080 and a refresh rate of up to 144 Hz (possibly only for Full HD+).

The chip is manufactured by TSMC using the current 6nm process in the mid-range segment.
