The Dimensity 8450’s APU is generally considered one of its standout features, potentially offering more raw AI compute power for specific generative AI applications. Both platforms enable advanced AI features in smartphones.
Imaging and Camera Support
These chips define the computational photography capabilities of the phones that use them.
- Snapdragon 8 Gen 3: Features the Spectra ISP (Image Signal Processor). It typically supports very high-resolution sensors (e.g., up to 200MP), concurrent processing from multiple cameras, and advanced computational photography features like real-time semantic segmentation for enhanced HDR and low-light performance.
- Dimensity 8450: Incorporates an Imagiq ISP. It also supports high-resolution sensors and multi-camera setups. A key focus is leveraging its powerful APU for AI-enhanced photography, such as real-time bokeh tracking, noise reduction, and video HDR processing.
The final camera quality depends heavily on the smartphone manufacturer’s lens hardware and software tuning. Both ISPs provide a powerful foundation for flagship-level camera systems.
Connectivity and Modem
Connectivity covers cellular, Wi-Fi, and Bluetooth capabilities.
- Snapdragon 8 Gen 3: Includes the integrated Snapdragon X75 5G modem. It is a mature modem platform known for strong performance, carrier aggregation, and global network support across both mmWave and sub-6 GHz bands in most regions. It also typically supports the latest Wi-Fi 7 and Bluetooth 5.4 standards.
- Dimensity 8450: Features an integrated 5G modem supporting sub-6 GHz networks. It also supports Wi-Fi 7 and Bluetooth 5.4. MediaTek modems are common in many global markets and offer strong, efficient performance.
The Snapdragon X75 modem may have an edge in areas where mmWave 5G is deployed or in specific network compatibility scenarios. For most users on sub-6 GHz networks, both will offer excellent connectivity.
