Today, Qualcomm announced the launch of the new Qualcomm® Snapdragon™ 845 mobile platform. Designed for technology-enthusiastic consumers and targeting top-level flagship mobile devices, Snapdragon 845 fully leverages Qualcomm's industry-leading mobile heterogeneous computing expertise to create a platform that supports immersive multimedia experiences including XR (extended reality) , on-device AI , and lightning-fast connection speeds. At the same time, it introduces a new secure processing unit (SPU) to bring vault-like security performance.
Immersion
The Snapdragon 845 Mobile Platform will enable consumers to shoot cinematic quality videos and break the boundaries between the real and virtual worlds . Snapdragon 845 integrates the Qualcomm Spectra™ 280 ISP and the Qualcomm® Adreno™ 630 visual processing subsystem. These new architectures bring high performance, realistic cinematic quality video capture, and outstanding imaging to flagship mobile devices. Snapdragon 845 can capture up to 64 times more high dynamic range color information than its predecessor to support video capture and playback on Ultra HD Premium displays, and its predecessor is also the mobile industry's first platform to support Ultra HD Premium content playback. This huge increase in color information includes 10-bit color depth that supports more than 1 billion shades of color, which can be displayed in the Rec.2020 wide color gamut, so that your precious imaging memories can be displayed in 1 billion shades of color.
除了视频拍摄体验的提升,全新 Adreno 630 视觉处理子系统架构将变革娱乐、教育和社交互动,使其更具沉浸感和直观性,旨在为包括 VR、AR 和 MR 在内的全新 XR 体验提供创新。骁龙845 是 首款支持室内空间定位(room-scale)六自由度(6DoF)和即时定位与地图构建(SLAM)的移动平台 ,从而实现诸如避免墙壁碰撞等特性。此外,与前代产品相比,骁龙845 所引入的“Adreno 视觉聚焦”可以显著降低功耗,提升视觉质量,并增强 XR 应用性能。
AI
Snapdragon 845 is Qualcomm's third-generation AI mobile platform. Compared with the previous generation system-on-chip (SoC), Snapdragon 845 brings nearly three times the overall AI performance improvement - turning mobile terminals into excellent personal assistants; simplifying the shooting of pictures and videos; improving the VR gaming experience, and making voice interaction more natural. Snapdragon 845 uses the Qualcomm Aqstic audio codec (WCD9341) and a low-power audio subsystem with excellent power consumption to achieve enhanced always-on keyword detection and ultra-low power voice processing, optimize voice-driven smart assistants, and enable users to interact with terminals through voice at any time throughout the day .
In addition to supporting Google TensorFlow and Facebook Caffe/Caffe2 frameworks, the Snapdragon Neural Processing Engine (SNPE) SDK now supports Tensorflow Lite and the new ONNX, helping developers easily use the frameworks of their choice , including Caffe2, CNTK and MxNet. Snapdragon 845 also supports the Google Android NN API.
Safety
As users’ demand for security grows, the security solutions in our mobile platforms are also evolving. As personal data stored in terminals has grown significantly, terminal users are in urgent need of enhanced privacy protection. In addition, payment companies are also looking for more secure authentication mechanisms to enhance reliability. Snapdragon 845 introduces a hardware-isolated subsystem, the Security Processing Unit (SPU) , which aims to add vault-like security features to the existing layers of Qualcomm’s mobile security solutions, thereby enhancing biometric authentication security and user/application data key management to encrypt important information.
connect
Snapdragon 845 features our most advanced suite of wireless technologies in a smartphone platform, supporting advanced LTE, Wi-Fi, and Bluetooth features . Snapdragon 845 integrates Qualcomm Technologies’ second-generation Gigabit LTE solution, the Snapdragon X20 LTE modem. Its lightning-fast connection speeds allow users to enjoy immersive XR experiences in more places, download a 3GB movie in 3 minutes before boarding a flight, and access large files or applications in the cloud at high speeds, just as if they were stored in the phone’s memory. The Snapdragon X20 modem supports a wide range of technology and band configurations, covering licensed, unlicensed, and shared spectrum, accelerating the adoption of Gigabit LTE around the world as operators prepare for 5G. The modem supports Category 18 LTE peak download speeds of up to 1.2Gbps , up to five-carrier aggregation, License Assisted Access (LAA), dual-SIM dual VoLTE, and 4x4 MIMO on up to three aggregated carriers.
Snapdragon 845 also supports advanced 60GHz 802.11ad Wi-Fi , adding support for diversity antennas for a more stable, multi-gigabit network experience up to 4.6Gbps; and integrates 802.11ac Wi-Fi with advanced features, which can achieve up to 16 times faster connection setup speeds compared to previous generations; dual-band concurrent (DBS) support for an expanding application portfolio; and 30% improvement in carrier-grade Wi-Fi network capacity utilization. The platform's proprietary improvements to Bluetooth 5 allow users to broadcast audio to multiple wireless speakers, smartphones or other terminals at the same time; in addition, it can reduce the power consumption of wireless earbuds by up to 50% compared to previous generations.
