Samsung Exynos W920 vs MediaTek Dimensity 8020 vs MediaTek Dimensity 7020

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 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.

MediaTek Dimensity 7020

The Mediatek Dimensity 7020 is a fast mid-range SoC with an integrated 5G modem. It includes two fast ARM Cortex-A78 cores at up to 2.2 GHz and six power efficient Cortex-A55 cores at up to 2 GHz (Octa-Core with Heterogeneous Multi-Processing). Furthermore, the chip integrates a IMG BXM-8-256 GPU, a Wi-Fi 5 modem, a LPDDR5 / LPDDR4X memory controller, a AI processing unit  and video de- and encoding.

The 5G modem supports NR 2CC and mixed duplex (TDD/FDD) and dual SIM. The download speeds can reach up to 2.77 Gbit/s.

Compared to the Dimensity 930, the 7020 offers the same specifications and seems to be a rebrand.

The Dimensity 930 and 7020 are manufactured in the modern 6nm process and should be very power efficient.
