Qualcomm Snapdragon 680 4G vs Mediatek Helio G100 vs Qualcomm Snapdragon 685 4G

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).

The MediaTek Helio G100 is an entry level ARM SoC (system-on-a-chip) that can be used in both smartphones and tablets (mainly Android). Technically comparable to the older Mediatek Helio G99 but with support for up to 200 MP main cameras.

The SoC integrates two ARM Cortex-A76 cores with up to 2.2 GHz for demanding tasks and six small ARM Cortex-A55 cores with up to 2 GHz clock speed in a power-saving cluster.

The integrated 4G LTE modem supports Cat-13 (400 Mbps download, 150 Mbps upload). Wi-Fi 5 (a/b/g/n/ac) is also on board. The memory controller supports LPDDR4x RAM with up to 4266 MHz.

A maximum of UFS 2.2 memory can be used for mass storage.

The MediaTek Helio G100 is manufactured using the 6nm process.

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.
