MediaTek Dimensity 7020 vs Samsung Exynos 9820 vs MediaTek Dimensity 900

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.

Samsung Exynos 9820

The Samsung Exynos 9 9820 is a mobile SoC for smartphones and tablets. It was announced late 2018 and was first integrated in the Samsung Galaxy S10 smartphones early 2019. The SoC integrates three clusters of processor cores with different architectures. Two big Samsung custom M4 cores clock up to 2.7 GHz and deliver peak performance. Two additional ARM Cortex-A75 are also for performance tasks and clock at up to 2.3 GHz. Finally, four small and power efficient ARM-Cortex A55 cores clock at up to 1.9 GHz are in the third cluster. The different clusters can run simultaneously thanks to DinamIQ.

The integrated LTE modem supports LTE-Advanced Pro Cat.20 (8CA 2 Gbps download, 3CA 316 Mbps upload). The integrated graphics card is a ARM Mali G76MP12 with 12 cores.

The performance of the CPU part is positioned in the high end segment for smartphone processors. The single core performance is, thanks to the big custom cores, a strong suit of the CPU and reaches the levels of Apples mobile SoCs. The direct competitor Snapdragon 855 can be left behind in single-core benchmarks like Geekbench and operates on par in multi-core benchmarks. The predecessor Exynos 9810 can be bested by around 17% in our first benchmarks with the Galaxy S10 Plus.

The SoC is produced at Samsung in the new 8nm LPP process that should also help with some of the performance gains.

MediaTek Dimensity 900

The Mediatek Dimensity 900 is a fast mid-range SoC with an integrated 5G modem. It includes two fast ARM Cortex-A78 cores at up to 2.4 GHz and six power efficient Cortex-A55 cores at up to 2 GHz (Octa-Core with Heterogeneous Multi-Processing). Furthermore, the chip integrates a 4 core ARM Mali-G68 MC4 GPU, a Wi-fi 6 modem, a LPDDR4x memory controller, a AI processing unit  and video de- and encoding.

The Dimensity 900 is manufactured in the modern 6nm process and should be very power efficient.
