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.
Rockchip RK3566

The Rockchip RK3566 is an entry-level ARM SoC (system-on-a-chip) introduced in 2020, which is primarily used in AIot devices and e-ink tablets, for example in Lenovo's Paper Smart. The chip is manufactured in 22nm and integrates four ARM Cortex-A55 cores with up to 2 GHz. As a GPU it integrates a ARM Mali-G52 MP2 (2 cores). Furthermore, a video decoder with H.264 and H.265 support is integrated, among other things.
Besides the CPU and graphics chip, the chip also integrates an LPDDR3/LPDDR4x memory controller, but no cellular modem. Das SoC beinhaltet ein Modem für Wi-Fi 5 (a/b/g/n/ac). Furthermore, an AI unit with 1 TOPS is installed.
