Camera & Imaging
The integrated image signal processors (ISPs) define the camera potential of devices using these chipsets.
- Snapdragon 7s Gen 3: Features a triple 12-bit Spectra ISP. It supports single cameras up to 200MP, dual cameras up to 32+32MP, and can record 4K video at 30fps. It includes computational photography features like multi-frame noise reduction.
- Dimensity 7400: Boasts a more advanced Imagiq 765 ISP. It supports single cameras up to 200MP or dual cameras at 32+32MP, but adds support for 4K HDR video recording. It also includes hardware-level depth engines for better bokeh effects and AI-enhanced noise reduction.
The Dimensity 7400’s ISP is generally considered more feature-rich, particularly for video recording. However, final camera quality heavily depends on the manufacturer’s lens hardware and software tuning.
Connectivity & Modem
This area highlights one of the traditional differentiators between the two brands.
- Snapdragon 7s Gen 3: Integrates the Snapdragon X63 5G Modem-RF System. It supports both sub-6GHz and mmWave 5G (in specific variants), Wi-Fi 6E, and Bluetooth 5.3. Qualcomm modems are often noted for their strong signal reception and consistency in various network conditions.
- Dimensity 7400: Includes a MediaTek 5G modem supporting sub-6GHz networks. It also supports Wi-Fi 6E and Bluetooth 5.3. Its 5G UltraSave 3.0+ technology is focused on reducing 5G power consumption.
The Snapdragon platform typically offers more comprehensive global 5G band support, including mmWave in certain regions, which can be a factor for users in areas where that technology is deployed.
AI & Additional Features
AI performance powers features from camera enhancements to voice assistants.
- Snapdragon 7s Gen 3: Leverages the Qualcomm AI Engine, which uses a hybrid architecture of the Hexagon Processor, GPU, and CPU to accelerate AI tasks. It supports popular AI frameworks.
- Dimensity 7400: Uses MediaTek’s APU 655 AI processor. This dedicated AI processing unit is designed to handle AI-camera enhancements, video summarization, and other on-device AI tasks efficiently.
Both offer capable AI performance for mid-range tasks. The efficiency of their respective AI processors contributes to features like live photo filters, speech recognition, and battery management.
