Qualcomm Snapdragon 685 4G vs Mediatek Helio G81
Qualcomm Snapdragon 685 4G
► remove from comparison
The Qualcomm Snapdragon 685 (SD685, SM6225-AD) 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 2.8 GHz (Kryo 265 Gold - Cortex-A73 derivate) and a power saving efficiency cluster with up to 1.9 GHz (Kryo 265 Silver - Cortex A53 derivate). Both clusters can also be used together. According to Qualcomm the SD685 is around 15% more CPU performance and 10% more GPU performance compared to the old SD680 (thanks to higher clock speeds).
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.
Mediatek Helio G81
► remove from comparison
The Mediatek Helio G81 is a mainstream ARM SoC for smartphones (mainly Android based) that was introduced in 2020. It is manufactured in a 12 nm FinFET process and integrates 8 CPU cores. Two fast ARM Cortex-A75 cores with up to 2 GHz for performance tasks and six small ARM Cortex-A55 with up to 1.7 GHz for efficiency. All eight cores can be used together thanks to Heterogeneous Multi-Processing support. The integrated GPU is a ARM Mali-G52 MC2 (MP2) with two clusters at up to 950 MHz. The SoC also integrates the HyperEngine that handles a dynamic management of CPU, GPU and memory.
Compared to the old Helio G80, the G81 offers support for 120Hz displays.
The SoC integrates furthermore a LTE radio with Cat-7 (download) / Cat-13 (upload) support, Wifi 5 (ac), Bluetooth 5.0, LPDDR4x 1800 MHz and eMMC 5.1 storage.
