The Snapdragon 855 features multi-gigabit 4G connectivity with the built-in Snapdragon X24 LTE modem, and the Snapdragon X50 can be added to support 5G for both Sub-6 GHz and mmWave frequency bands. Not just that, it also offers powerful next-generation Wi-Fi performance via the Qualcomm Wi-Fi 6-ready mobile platform, offers WPA3 security, supports mmWave Wi-Fi and industry first 802.11ay-based platform for speeds up to 10 Gbps and brings wire-equivalent low latency.

Moreover, the new Qualcomm Spectra 380 ISP integrates numerous hardware accelerated computer vision (CV) capabilities such as hardware-based depth sensing enabling video capture, object classification, and object segmentation all in real-time in 4K HDR at 60fps, which lets you capture a video and accurately replace selected objects or backgrounds in the scene in real-time all with 4K HDR resolution. It is also first to support video recording using HDR10+ and also has support for HEIF file format encoding.

This flagship chipset also includes new Elite Gaming Experience that includes;

• Cinematic color grading in true HDR (>1 billion colors)
• Filmic tone-mapping, demanding physically based rendering (PBR)
• Support for the Vulkan 1.1 graphics library
• Custom algorithms designed to reduce dropped frames by >90%.
• Multiplayer gaming is improved by reducing latencies using existing 802.11 standards
