Qualcomm Snapdragon 6s Gen 3 vs Qualcomm Snapdragon 660 vs Qualcomm Snapdragon 662
Qualcomm Snapdragon 6s Gen 3
► remove from comparison
The Qualcomm Snapdragon 6s Gen 3 (SM6375) is an ARM-based SoC for smartphones and tablets in the upper mid-range segment. Launched in mid-2024, the chip offers two fast ARM Cortex-A78-based cores with up to 2.3 GHz and 6 ARM Cortex-A55-based power cores with up to 2 GHz.
The design of the chip and the technical data are similar to the older Snapdragon 695. The Qualcomm Snapdragon 6s Gen 3 is manufactured using the older 6 nm technology and has a higher maximum clock rate as well as some new features compared to the 695. As a result, the performance in our tests with the Motorola Moto G85 is also slightly higher than the older Snapdragon 695.
The integrated graphics card is the Adreno 619. The 5G modem called Snapdragon X51 achieves a maximum of 2.5 GBit / 0.8 GBit (download/upload) and supports mmWave. The FastConnect 6200 subsystem offers Bluetooth 5.2 and Wi-Fi 5 (8x8 sounding, dual band, 2x2). All important satellite positioning systems such as GPS, QZSS, GLONASS, SBAS, Beidou and Galileo are supported.
The image signal processor for the cameras supports 3 cameras. Up to 108 megapixels are possible with the main camera and the recording of images in HEIC format is also possible.
Qualcomm Snapdragon 660
► remove from comparison
The Qualcomm Snapdragon 660 (SD660) is a fast mid-range ARM-based SoC largely found on Android tablets and smartphones. Announced in mid 2017, the SD660 is the successor to the Snapdragon 625. It features 8 Kryo 260 cores (custom design, 64-Bit capable) that are divided in two clusters. A fast cluster of four cores with up to 2.2 GHz and a power saving efficiency cluster with up to 1.8 GHz. Both clusters can also used together.
In addition to the 8 CPU cores, the SoC integrates a mid range Adreno 512 GPU with a LPDDR4 memory controller (dual-channel 1866 MHz) and supports Wi-Fi (802.11ac + MIMO, max. 867 Mbps), Bluetooth 5, and LTE (X12 LTE modem with up to 600 Mbps download and 150 Mbps upload).
Performance
In Benchmarks of the Oppo R11, the CPU part of the Snapdragon SD660 performs between former high end Socs like the Snapdragon 821 in the Pixel XL and the Snapdragon 835. The graphics performance is however much lower, as the Adreno 512 is only a slight upgrade of the older Adreno 510 (due to the higher clock speed).
CPU
The Snapdragon 660 is based on a similar concept as ARM's big.LITTLE, which combines a low power CPU cluster (2x Kyro clocked at up to 1.8 GHz) and a performance CPU cluster (2x Kyro clocked at up to 2.2 GHz). The clock speed of each cluster can be individually adjusted (but not per core) and the lowest clock speed is 310 MHz (unverified).
Power Consumption
Thanks to the new 14 nm process, the energy efficiency has been improved noticeably compared to its 20 nm predecessors.
Qualcomm Snapdragon 662
► remove from comparison
The Qualcomm Snapdragon 662 is a lower mid-range ARM-based SoC largely found in Android tablets and smartphones. It features 8 Kryo 260 cores (custom design, 64-Bit capable) that are divided in two clusters. A fast cluster of four cores with up to 2 GHz (Kryo 260 Gold - Cortex-A73 derivate) and a power saving efficiency cluster with up to 1.8 GHz (Kryo 260 Silver - Cortex A53 derivate). Both clusters can also be used together.
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 (X12 LTE modem with up to 600 Mbps download and 150 Mbps upload).
Power Consumption
Thanks to the new 11 nm LPP process, the energy efficiency should be quite good.
