MediaTek Dimensity 8020 vs Qualcomm Snapdragon 778G 4G

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.

Qualcomm Snapdragon 778G 4G

The Qualcomm Snapdragon 778G 4G (SDM778G 4G Mobile Platform) is a fast mid-range ARM-based SoC largely found on Android tablets and smartphones. It integrates eight cores (octa-core) divided into two clusters. A fast performance cluster with four cores based on the ARM Cortex-A78 architecture with up to 2.4 GHz and a power efficiency cluster with four small ARM Cortex-A55 cores at up to 1.8 GHz. Depending on the workload only single clusters or all cores can run at different clock speeds. In contrast to the Snapdragon 778 5G, the 778G 4G does not offer a 5G modem, but only supports 4G/LTE.

Thanks to the new Cortex-A78 cores, the CPU performance increases by up to 40% compared to the old Snapdragon 768G according to Qualcomm. In our benchmarks, the 778G is able to reach the performance of the old high end chip Kirin 990. 

The integrated Qualcomm Adreno 642L offers a 40% higher performance compared to the old Adreno 620 in the predecessor. This is partly thanks to the fast memory controller with LPDDR5-3200 support.

The integrated 6th gen AI engine called Hexagon 770 offers a 2x improvement and up to 12 TOPS of performance. The Spectra 570 ISP (image signal processor) supports up to three cameras. The satellite system supports all major standards like Beidou, Galileo, GLONASS and GPS.

The G specifies an optimized SoC for gaming and e.g. Qualcomm offers updates for the graphics driver.

The Snapdragon 778G is manufactured in the modern 6 nm process at TSMC (vs the 5LPE of the 780G).
