Qualcomm Snapdragon 7s Gen 2
► remove from comparison
The Qualcomm Snapdragon 7s Gen 2 (SM7435-AB) is an ARMv9-A-based SoC for tablets and smartphones in the upper mid-range segment.
The Qualcomm Snapdragon 7s Gen 2 integrates a total of 8 cores divided into two clusters. The ARM Cortex-A78 cluster for high performance offers four cores with up to 2.4 GHz. The remaining 4 cores are based on the more energy-efficient A55 architecture and can be clocked at up to 1.95 GHz. All cores can run simultaneously or just a single cluster.
The SoC is similar to the Snapdragon 7 Gen 1 which offers a slightly lower clocked efficiency cluster and a different named GPU. The similar named Snapdragon 7+ Gen 2 is clearly faster with newer CPU cores. Although the naming suggest it, there was no Snapdragon 7s Gen 1.
LPDDR5 RAM is supported, with a frequency of up to 6,400 MHz.
The Snapdragon X62 5G modem is used as the modem. It supports a range of SA and NSA 5G mmWave and sub-6 GHz frequencies as well as Dynamic Spectrum Sharing (DSS). The X62 can achieve a maximum downlink speed of up to 2.9 Gbit/s in 5G networks.
The Adreno 710 forms the graphics subsystem. The GPU is capable of driving FHD+ displays at up to 144 Hz.
The Qualcomm Snapdragon 7s Gen 2 is manufactured using the modern 4nm EUV process.
Qualcomm Snapdragon 7 Gen 1
► remove from comparison
The Qualcomm Snapdragon 7 Gen 1 (SM7450-AB 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. Four fast cores based on the ARM Cortex-A710 architecture with up to 2.4 GHz and four additional A510 based cores with up to 1.8 GHz in a power efficiency cluster.
According to ARM, the performance cores are 10 percent faster and 35 percent more efficient than the old Cortex-A78 cores. The efficiency cores are supposed to be 35 percent more powerful and 20 percent more efficient than the old Cortex-A55 cores. The Snapdragon 7 Gen 1 supports up to 16 GB of LPDDR5-3200 RAM and UFS-3.1 flash memory. The SoC uses the integrated Adreno 644 for graphics card.
The Adreno graphics chip supports HDR10, HDR10+, Dolby Vision as well as HLG and relies on a hardware-accelerated H.265 and VP9 decoder. The 7th generation Qualcomm AI Engine offers features like Camera Deep Learning Face Detect (DLFD) and Video Super Resolution (VSR).
The Qualcomm Spectra Triple ISP (Image Signal Processor) enables three cameras to capture photos and videos simultaneously. The chip supports 200-megapixel cameras as well as 4K HDR video recording.
The Snapdragon X62 5G modem integrated in the SoC allows simultaneous data transfers of 5G-mmWave as well as sub-6 GHz, enabling bandwidths of up to 4.4 GBit/s. Qualcomm's FastConnect 6700 is responsible for local communication, which supports Bluetooth 5.2 and Wi-Fi 6E, among other things. Speeds of up to 2.9 GBit/s are to be achieved via Wi-Fi 6E.
The SoC is manufactured in a modern 4 nm process at Samsung.
