MediaTek Dimensity 6020 vs Qualcomm Snapdragon 680 4G vs MediaTek Dimensity 820
MediaTek Dimensity 6020
► remove from comparison
The Mediatek Dimensity 6020 is a lower mid-range SoC with an integrated 5G modem. It includes two fast ARM Cortex-A76 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). The specifications are similar to the old Dimensity 700 SoC.
Furthermore, the chip integrates a 2 core ARM Mali-G57 MC2 GPU, a Wi-fi 5 modem, a LPDDR4x-2133 memory controller, a AI processing unit (APU 3.0) and video de- and encoding.
The Dimensity 6020 is manufactured in the older 7nm process like the Dimensity 700.
Qualcomm Snapdragon 680 4G
► remove from comparison
The Qualcomm Snapdragon 680 (SD680, SM6225) is a mid-range ARM-based SoC largely found on Android tablets and smartphones. It features 8 Kryo 265 cores (custom design, 64-Bit capable) that are divided in two clusters. A fast cluster of four cores with up to 2.4 GHz (Kryo 265 Gold - Cortex-A73 derivate) and a power saving efficiency cluster with up to 1.8 GHz (Kryo 265 Silver - Cortex A53 derivate). Both clusters can also be used together. Compared to the older Snapdragon 665, the clock speeds are higher.
In addition to the 8 CPU cores, the SoC integrates a mid range Adreno 610 GPU with a LPDDR4 memory controller (dual-channel) and supports Wi-Fi (802.11ac + MIMO, max. 867 Mbps), Bluetooth 5, and LTE (X11 LTE modem with up to 390 Mbps download).
The SoC is produced in 6nm (compared to the older 11nm LPP process of the similar Snapdragon 665).
MediaTek Dimensity 820
► remove from comparison
The Mediatek Dimensity 820 is a fast mid-range SoC with an integrated 5G modem. It includes four fast ARM Cortex-A76 cores at up to 2.6 GHz and four power efficient Cortex-A55 cores at up to 2 GHz (Octa-Core with Heterogeneous Multi-Processing). Furthermore, the chip integrates a 5 core ARM Mali-G57 MC5 GPU, a Wi-fi 5 modem, a LPDDR4x memory controller, a AI processing unit (APU 3.0) and video de- and encoding. The Dimensity 820 is manufactured in the modern 7nm process and should be very power efficient.
