Tencent Technology Guo Xiaofeng December 7 report
US time on the 6th, Xiaolong Technology Summit into the next day. Qualcomm released specific features and parameters of the Snapdragon 845 mobile platform. Among them, XR (augmented reality), the terminal side AI, the introduction of a new security processing unit (SPU) to become the biggest bright spot.
Immersion: The Snapdragon 845 mobile platform will enable consumers to capture movie-level video and break the boundaries between reality and the virtual world. Snapdragon 845 integrates Qualcomm Spectra 280 ISP and Qualcomm Adreno 630 vision processing subsystem. These new architectures bring high-performance, immersive movie-quality video capture to the flagship mobile device, as well as great video.
Compared to its predecessors, the Snapdragon 845 captures up to 64x higher dynamic range color information to support video capture and playback on the Ultra HD Premium display, while its predecessors are the first in the industry to support Ultra HD Premium Content playback platform. This dramatic increase in color information includes a 10-bit color depth that supports more than 1 billion colors, which can be displayed in the wide color gamut of Rec.2020, enabling your precious image memory to be displayed in 1 billion colors.
In addition to the enhanced video capture experience, the new Adreno 630 visual processing subsystem architecture revolutionizes entertainment, education and social interaction, making it more immersive and intuitive, designed to deliver on the new XR experience including VR, AR and MR Innovation. The Snapdragon 845 is the first mobile platform to support room-scale 6 DOF (6DoF) and real-time location and map construction (SLAM) for features such as avoiding wall collisions. In addition, Snapdragon 845 introduces "Adreno visual focus" that dramatically reduces power consumption, improves visual quality, and enhances XR application performance over previous generations.
Artificial Intelligence (AI): The Snapdragon 845 is Qualcomm Technologies' third-generation AI mobile platform. The Snapdragon 845 brings nearly three times the AI overall performance improvement over the previous system-on-chip (SoC) - transforming mobile devices into great personal assistants; simplifying picture and video capture; enhancing VR Game experience, and make voice interaction more natural.
Snapdragon 845 With the Qualcomm Aqstic audio codec (WCD9341) and power-hungry low-power audio subsystem, enhanced always-on keyword detection and ultra-low power voice processing, voice-optimized intelligent assistant so that Users can interact with the terminal at any time throughout the day.
In addition to the Google TensorFlow and Facebook Caffe / Caffe2 frameworks, the Snapdragon Neural Processing Engine (SNPE) SDK now supports both Tensorflow Lite and the new ONNX, making it easy for developers to use the framework of their choice, including Caffe2, CNTK and MxNet . Snapdragon 845 also supports Google Android NN API.
Security: Due to the substantial growth of personal data stored in the terminal, end users urgently need to enhance privacy protection. In addition, payment companies are looking for more secure authentication mechanisms to enhance reliability. Snapdragon 845 introduces the Hardware Isolation Subsystem & Security Processing Unit (SPU), designed to add security features such as vaults to existing layers of Qualcomm Technologies' mobile security solutions to enhance the security of biometric authentication and User / Application Data Key Management to encrypt important information.
Connectivity: The Snapdragon 845 is equipped with the latest wireless technology suite on the smartphone platform that supports advanced LTE, Wi-Fi and Bluetooth features. Snapdragon 845 integrates Qualcomm Technologies' second-generation gigabit LTE solution & nbsp; & nbsp; Snapdragon X20 LTE modem.
For example, the connection speed allows users to enjoy the immersive XR experience in more places, download a 3GB movie in 3 minutes before boarding, and get large cloud files or applications at high speed, as these files and programs are stored in the mobile phone Same in memory
The Snapdragon X20 modem supports a wide range of technology and frequency band configurations, coverage licenses, license-exempt and shared spectrum, accelerating the worldwide adoption of gigabit LTE when operators prepare for 5G. The modem supports Category 18 LTE peak download speeds of up to 1.2Gbps, up to five carrier aggregation, LAA, dual SIM dual VoLTE, and 4x4 MIMO on up to three aggregated carriers.
The Snapdragon 845 also supports advanced 60GHz 802.11ad Wi-Fi and adds support for diversity antennas to enable more stable, multi-gigabit network speeds up to 4.6Gbps; and integrates 802.11ac Wi with advanced features -Fi, enabling up to 16x faster connection setup speeds than its predecessors; dual-band concurrency (DBS) for a growing portfolio of applications; and 30% increase in capacity utilization for carrier-grade Wi-Fi networks. The platform's proprietary enhancements to Bluetooth 5 allow users to broadcast audio to multiple wireless speakers, smartphones or other terminals at the same time, and reduce the power consumption of their wireless earbuds by up to 50% compared to their predecessors.
Performance: With heterogeneous computing, the new architecture of the Snapdragon 845 is designed to improve the user experience while dramatically improving performance and battery life. Snapdragon 845 uses a new imaging and visual processing architecture, power consumption in video capture, gaming and XR applications up to 30% (compared with the previous generation). Thanks to the new Adreno 630, image performance and energy efficiency can be increased up to 30% compared to the previous generation. The new Qualcomm Kryo 385 architecture, built on Arm Cortex technology, delivers up to 25% performance improvement over previous generations of games, application startup time and heavy-duty applications.
Alex Katouzian, senior vice president and general manager of mobile business at Qualcomm Technologies, Inc., said: "We are going to change the mobile experience with an overall increase in visual processing, AI, security and connectivity. Snapdragon 845 mobile platform will inspire a new round of innovation wave, change the way people use the mobile terminal to make life more beautiful. & rdquo;
It is understood that commercial terminal equipped with the platform is expected to begin shipping in early 2018. The Snapdragon 845 will support terminals including mobile phones, XR headsets, always connected PCs and more.
