Samsung Exynos W920 vs MediaTek Dimensity 7050 vs MediaTek Dimensity 930

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 7050

The Mediatek Dimensity 7050 (Mediatek MT8791N/TN)  is a mid-range ARM SoC (system-on-a-chip) that can be used in both smartphones and tablets (mainly Android). The SoC integrates two ARM Cortex-A78 cores with up to 2.6 GHz for demanding tasks and six power-saving ARM Cortex-A55 cores with clock rates of up to 2 GHz. The specifications are identical to the old Dimensity 1080.

The chip has an integrated sub-6 GHz 5G modem including dual-SIM support that can reach a maximum download speed of up to 2.77 Gbit/s. Wi-Fi 6 (802.11ax) is supported as well as Bluetooth 5.2.

The memory controller copes with LPDDR4x or LPDDR5 working memory as well as UFS 3.1 mass storage. As an integrated graphics card, the SoC uses the ARM Mali-G68 MC4, which supports displays with 120 Hz as well as HDR10+ at a maximum resolution of 2,520 x 1,440 pixels.

The MediaTek Dimensity 7050 is still manufactured in 6 nm.

MediaTek Dimensity 930

The Mediatek Dimensity 930 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 920, the 930 has a slower clocked CPU, but a faster GPU.

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