Samsung Exynos W920 vs MediaTek Dimensity 8050 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 8050

The MediaTek Dimensity 8050 is an ARM-based SoC (System-on-a-Chip) manufactured at TSMC using the 6nm process.  It supports all current mobile standards including dual-SIM 5G (5G SA & NSA, max 4.7 Gbps download and 2.5 Gbps upload). The SoC also supports Wi-Fi 6 and Bluetooth 5.2.

The MediaTek Dimensity 8050 was specially designed for use in Android smartphones and is classified in the upper mid-range in terms of performance.

The CPU part consists of three clusters: a fast performance core, based on the ARM Cortex A78 architecture and clocked at up to 3 GHz. The second cluster consists of three Cortex-A78 cores with up to 2.6 GHz. Four ARM Cortex-A55 cores with up to 2 GHz are installed as a power-saving cluster.

The integrated ARM Mali-G77 MC9 graphics unit can drive displays with a resolution of up to 2,560 x 1,080 and a refresh rate of up to 144 Hz (possibly only with Full HD+).

Technically, the SoC is similar to the older Dimensity 1300.

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.
