Qualcomm Snapdragon 732G vs Qualcomm Snapdragon 870 5G

Qualcomm Snapdragon 732G

The Qualcomm Snapdragon 732G (SD732G Mobile Platform) is a fast mid-range ARM-based SoC largely found on Android tablets and smartphones. It integrates eight cores (octa-core) divided into two clusters. A fast performance cluster contains two ARM Cortex-A76 cores clocked at up to 2.3 GHz and a power efficiency cluster with six small ARM Cortex-A55 cores at up to 1.8 GHz. Depending on the workload only single clusters or all cores can run at different clock speeds. Compared to the 730G, the 732G offers a 100 MHz higher A76 CPU clock.

Compared to the normal Snapdragon 730, the 732G is optimized for gaming. This means the graphics card is higher clocked (also compared to the 730G, Qualcomm stateds 15% more performance) and the chip also offers optimized WiFi. The GPU also supports higher resolutions. Furthermore, the SoC is able to record videos in 720p with up to 960 fps.

The chip includes a range of other features like a fast X15 LTE radio (800 Mbits Cat 15 download, 150 Mbps Cat 13 upload), one of the first Wi-Fi 6 wireless radios (802.11ax), satellite positioning (GPS, QZSS, GLONASS, SBAS, Beidou, Galileo), USB-C 3.1, Spectra 350 ISP, Hexagon 688 DSP, H.265 4K30 video en- and decode, an LPDDR4X-3733 dual-channel memory controller and a Adreno 618 Grafikkarte.

The Snapdragon 732G is manufactured in the modern 8 nm process at Samsung.

Qualcomm Snapdragon 870 5G

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.
