Qualcom's next -generation chip "Snapdragon 820" is clear
Snapdragon 820 consisting of numerous modules such as CPU, GPU, DSP, ISP
Among the series that bears the name of Snapdragon, the Snapdragon 820, which is the top chip, is a new generation quad -core 64bit chipset, which has been handed from the design part of the CPU.Maximum frequency 2.The 2GHz CPU is a custom chip called "Kryo", with the GPU "Adreno 530", the modem "X12 LTE", the "Spectra Camera ISP" that controls the camera, and the "Hexagon 680" DSP "Hexagon 680"DPU for display display, VPU for video processing, etc. are combined.
In addition, "HAVEN" for security and authentication, "ZEROTH" that realizes artificial intelligence through machine learning, "Symphony System Manager", which is responsible for power management, and "Symphony System Manager", "appropriate and fast charging according to the specifications of the equipment.Quick Charge 3.Various platforms such as "0" are also integrated.

According to Tim McDonnod, a company marketing vice president who stood at the keynote speech at the beginning of the recital, Snapdragon will be installed on a total of 932 million devices this year, which has been 30 years since its establishment.Reported.The new Snapdragon 820 has already been adopted for over 70 devices, appealing the reliability of the Snapdragon brand.
クアルコムは設立30年を迎えた累計で9億3200万ものデバイスにSnapdragonが搭載通信性能は大幅にアップCPUは2倍、GPUは40％、映像・音声処理用DSPは3倍性能アップし、電力効率も向上した
In Snapdragon 820, not only the processing performance of the CPU but also the communication performance has evolved significantly.The 4G network supports up to 600Mbps down / up to 150Mbps, and covers not only streaming playback of 4K videos but also up streaming.Wi-Fi does not sacrifice speed even when using multiple users at the same time, IEEE 802.High-speed communication standard for short-range high-speed communication that uses 11ac MU-MIMO and 60GHz band to achieve up to 3Gbps or more IEEE 802.Compatible with 11AD.It also supports LTE-U (Unlicensed), which can perform high-speed communication in a limited area due to frequency bands and radio waves that do not require license, and LTE + Wi-Fi aggregation, which uses LTE and Wi-Fi simultaneously to speed up.
In addition, the GPU Adreno 530, which improved the performance of 40 % compared to the previous generation Adreno 430, enabled more high -quality real -time 3D CG processing.In terms of audio, it is also implemented at the hardware level that realizes realistic surround not only when using headphones but also with a 2ch speaker with a built -in terminal.
3D CGのリアルタイムレンダリングでは鏡面処理も軽々とこなす。布の質感などもリアルに再現In the camera, the Spectra Camera ISP chip achieves three times the performance, 10 times the power efficiency of the previous generation, a powerful noise reduction function when shooting a dark place, and a function to improve the brightness and ease of viewing during backlight.In addition, it also has a function to maintain multiple people and face recognition at the same time, and to maintain recognition in real time even if they move around.
動いても人物・顔認識した複数の被写体を自動で追従する暗所撮影時に発生しがちなノイズを抑制し、被写体をよりきれいな写真で残せる逆光でこれまでは黒つぶれしていたような部分でもくっきり見えるヘッドフォンに加え、端末内蔵のステレオスピーカーでもサラウンドサウンドを実現する$$Zeroth技術により、カメラで捉えているシーンを自動判定日常のユースケースでは前世代から30％も電力消費が少ないとしているFurthermore, the zeroth platform of the artificial intelligence technology based on deep learning has a mechanism to instantly judge what the camera is captured with with the local database in the terminal.By applying this, in the image viewer app, etc., the recognized scenes and objects are tagged to automatically categorize them, and for example, they are quickly searched and browed from the categorized in the form of "people", "shores", and "document data".You can do it.
With the above performance improvement, power consumption at Snapdragon 820 at the daily use level has been reduced by about 30 % from Snapdragon 810.Since these performance and technology can be applied to devices in all fields other than smartphones in the future, Tim McDonnod will, for example, a device equipped with a processor that uses Snapdragon 820 technology, for example, a high -speed graphic process on multiple screens.He said that it would appear in a VR device to be performed, a drone that shoots 360 degrees around 4K resolutions, automatic driving and driving support, cars that provide infotal, or medical devices and security cameras.
The device equipped with Snapdragon 820 will be released in order in the world wide, including Japan, in 2016.At one point, there were rumors that the eight -core version of Snapdragon 820 appeared, but there is no fact that it is currently being considered.
