Qualcomm Snapdragon 6s Gen 3 vs Qualcomm Snapdragon 870 5G
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 870 5G
► remove from comparison
The Qualcomm Snapdragon 870 5G Mobile Platform (SM8250-AC) is a high-end smartphone and tablet SoC that Qualcomm announced in mid 2021. The SoC integrates a fast ‘Prime Core’ that clocks up to 3.2 GHz and three additional ARM Cortex-A77 performance cores, which can reach up to 2.42 GHz. These are complemented by four power-saving ARM Cortex-A55 cores that clock up to a maximum of 1.8 GHz. Compared to the similar and older Snapdragon 865+, the Prime Core clocks 100 MHz faster and the GPU is slightly higher clocked.
Therefore, the Snapdragon 870 is slightly faster than the old Snapdragon 865 and 865 Plus and slots in behind the high end Snapdragon 888.
The Mobile Platform integrates a Qualcomm X55 5G modem with Sub-5 and mmWave support and global 5G bands with up to 7.5 GBit/s (download) speed. The SmartConnect 6800 modem supports Wi-Fi 6 with 8x8 MU-MIMU and 60 GHz 11ay up to 10 Gbps.
The integrated GPU is still called Adreno 650 and offers a slightly higher clock speed of 670 MHz.
The on board Hexagon 698 DSP now offers a KI performance of up to 15 TOPS (up from 7 TOPS in the 855) and still uses a combination of CPU, GPU, HVX and Tensor cores. The Spectra 480 ISP is also untouched. The integrated Computer Vision Engine (CV-ISP) now supports Dolby Vision, 8K videos and 200 megapixel photos.
The built-in memory controller supports LPDDR5 with up to 2,750 MHz and LPDDR4X with 2,133 MHz.
The SoC is manufactured in the modern and power efficient 7nm process.
