US time on the morning of December 6, Qualcomm's flagship mobile platform - Snapdragon 845 at the second Qualcomm Snapdragon technology summit grand release.From the introduction of Qualcomm's first smart phone Snapdragon S1 in 2007, we witnessed the Xiao Dragon 10 years of growth every breakthrough, Xiao Long 845 Xiaolong ten years as the flagship, even more attention.
It is understood that the Snapdragon 845 is the flagship processor of the new generation Launched for more than three years. Alex Katouzian, Qualcomm Technologies, Inc. senior vice president and general manager of mobile services, said partners and partners continue to test the hardware, software and ecosystem partners Discussing market changes over time, combined with thousands of hours of testing, took more than three years. "We are two years longer than the blue whale, the oldest mammal in our life, to get pregnant."
Compared to the 835, Snapdragon 845 in immersive experience, AI, security, connectivity, performance in all six directions have improved to varying degrees. Qualcomm official said, Snapdragon 845 mobile platform designed for consumers keen technology, and for Top flagship mobile terminal, will support various forms of terminals, including mobile phones, XR headsets, always connected PC, etc. Currently, Snapdragon 845 Snapdragon 845 mobile platform is now available to customers, equipped with the platform Commercial terminals are expected to begin shipping in early 2018.
Snapdragon 845 mobile platform uses Samsung's second generation 10nm process technology, the mobile platform introduces a new Qualcomm third-generation Kryo 385 eight-core CPU, up to 2.8GHz maximum frequency up to 30% higher than the previous generation.Also has Adreno 360 visual processing Subsystem, the Hexagon 685 DSP, the Adreno 630, the Spectra 280 ISP, and Qualcomm's Quick Charge 5, the latest fast-charge technology, which takes only 15 minutes from 0-50%.
The Snapdragon 845 integrates Qualcomm's second-generation gigabit modem, the X20 LTE, with up to 1.2Gbps download speeds and up to five LAA, dual-card dual-VoLTE, and up to three 4x4 MIMO over converged carriers; advanced 60GHz 802.11ad Wi-Fi enabled; integrated 802.11ac Wi-Fi, Bluetooth 5 with 02.11ac Wi-Fi Up to 16x faster connection setup than previous generations ; Dual-band concurrency (DBS) to support a growing portfolio of applications; and 30% increase in capacity utilization of carrier-grade Wi-Fi networks.
Xiaolong 845 biggest bright spot lies in the immersive experience, AI, independent security unit SPU and other aspects of the upgrade.
Qualcomm believes that immersive experience is to capture the true image of the world to provide a better experience and AR, VR, MR together set creative XR concept, based on the Snapdragon platform has launched more than 20 XR terminals .
The Spectra 280 ISP is Qualcomm's second-generation ISP that offers the best in photo and video experience, with the Snapdragon 845 supporting display and playback on the Ultra HD Premium screen, DXOMark being the # 1 Pixel 2 and having won 98 points high, Qualcomm is expected to Snapdragon 845 terminal equipment score will be more than 100. Color, the Snapdragon 845 supports more than 1 billion shades of 10-bit color depth, the resolution has been 64 times the upgrade.In addition, Support Rec.2020 color gamut standard.Multi-frame noise reduction, high-speed shooting, dynamic shooting enhancements and other functions, you can achieve real-time movie shooting, photos, insert dynamic pictures.
Immersive experience, we can see that almost all of the modules are lit, Qualcomm said, these lit modules share the CPU calculation, you can achieve maximum performance.Further explanation of the speaker, the hardware level, Qualcomm Heterogeneous computing was introduced at the software level, as well as heterogeneous scheduling for heterogeneous computing analysis, heterogeneous engines exist in 845. Multiple processors running an application at the same time, all with minimal voltage and speed Will be slower, but the effect is the same, to achieve the lowest efficiency.
Qualcomm considers AI a transformative technology that infuses AI into every aspect of life in the future, and Qualcomm expects the market for AI hardware and software ecosystem to reach 160 billion U.S. dollars by 2025. The development of AI is undergoing a transformation from the cloud to Terminal. On the one hand terminal computing capabilities to enhance; the other hand, the user connection experience, privacy, and reliability needs, have promoted the transfer of AI to the terminal.
Qualcomm appears to see explosive growth in the use of AI in the future, mainly in the areas of augmented reality, immersive gaming experience, voice and health monitoring.
The security needs of users are also growing, security, Snapdragons 845 introduced for the first time the hardware isolation subsystem - a separate security unit SPU, Qualcomm called the security island.According to Qualcomm, Qualcomm security system equipped with other manufacturers The key difference between Secure Cryptography chips is that system-level security, including HLOS (operating system level), TrustZone, and SPU, provides users with a choice of multiple security solutions, of which the SPU provides strong insurance as a standalone security unit Security at the library level, read-in and storage of user's bioinformatics, and verification of information can all be done in the SPU.
