Qualcomm reveals Snapdragon 845 Specs and Features

Qualcomm officially announced yesterday, the arrival of their latest flagship mobile platform — the Snapdragon 845. Today, the company unveiled what’s under the hood of the Snapdragon 845 including the new features it will bring into the mobile computing world.

Qualcomm‘s Snapdragon chips are not just processors but rather a complete platform for internal hardware which include modems, GPU’s, camera modules, WiFi units and more. As such the new Snapdragon chip will include new and improved graphics in the form of Adreno’s 630 GPU, an updated Qualcomm Spectra 280 image signal processor (ISP), a new AI system, the latest Snapdragon X20 LTE modem and the Kryo 385 CPU, among others.

The new Adreno 630 enables devices to capture 64x higher dynamic range color information for video capture and playback on Ultra HD displays. It also has improved color depth for better 4K/Ultra HD video viewing. Qualcomm updated the chips AI and biometric security system by implementing smarter voice commands and adding a secure processing unit (SPU).

As for connectivity, the Snapdragon 845’s X20 LTE modem supports the LTE Cat 18 category bringing with it peak downloads of1.2Gbps, up to 5x carrier aggregation, License Assisted Access (LAA), Dual SIM-Dual VoLTE, and 4×4 MIMO.
