This architecture typically delivers a substantial increase in AI performance, often quoted as up to 4.35x faster than its predecessor for certain models. This enhances features like camera processing, voice assistants, and on-device language models.
Connectivity and Modem
Both chipsets offer premium connectivity, but the newer model includes more advanced specifications.
- Snapdragon 8 Gen 1: Integrated the Snapdragon X65 5G Modem-RF System, supporting peak download speeds up to 10 Gbps. It also featured the FastConnect 6900 system for Wi-Fi 6E and Bluetooth 5.2.
- Snapdragon 8 Gen 2: Integrates the newer Snapdragon X70 5G Modem-RF System, which introduces AI-enhanced antenna tuning and supports peak download speeds up to 10 Gbps. For wireless connectivity, it uses the FastConnect 7800 system, adding support for Wi-Fi 7 (when available) and Bluetooth 5.3 with lower latency audio.
Imaging and Camera Support
The Spectra Image Signal Processor (ISP) is crucial for camera capabilities.
- Snapdragon 8 Gen 1: Featured the 18-bit Spectra ISP, capable of capturing photos from three 36MP cameras simultaneously or an 8K HDR video.
- Snapdragon 8 Gen 2: Upgrades to a new cognitive ISP, the Qualcomm Spectra ISP. It supports real-time semantic segmentation for optimizing different parts of a photo individually (like face, sky, hair) and can capture photos from three 36MP cameras or video from two 64MP cameras simultaneously. It also adds support for the AV1 codec for decoding 8K HDR video at 60 fps.
