Qualcomm's High-profile Snapdragon 845 finally unveiled the mystery, as the expected new processor has greatly improved in many ways, from which it can glimpse Qualcomm's vision of the 2018 smartphone market, and the outside world can grasp some clues to the new market trend in the next 1 years. Snapdragon 845 uses Samsung Electronics (Samsug Electronics) 10 nm process, and Qualcomm uses the new Kryo 385 central processing Unit (CPU) to make some significant improvements in the new processor. Kryo 385 uses arm (ARM) The latest A75 and A55 CPU core customer-made version, A75 is faster than the previous version of CPU processing speed 30%, the time pulse 2.8 GHz. Qualcomm also in Snapdragon 845 implanted 2MB L3 cache memory, To improve CPU efficiency and hysteresis. Kryo 385 also contains arm DYNAMIQ system controllers that can further improve efficiency and hysteresis, especially for performing tasks such as artificial intelligence (AI). The performance of the graphics processor (GPU), or Qualcomm's so-called ' visual processing subsystem ' (visual processing subsystem) is also upgraded. Qualcomm's new Adreno 630 is a new generation GPU with a completely redesigned architecture that improves performance by 30% compared to Snapdragon 835, and saves 30% power when the same performance is maintained. Overall, Snapdragon 845 still uses the Samsung 10 nm process, but both performance and power consumption have improved dramatically. Snapdragon 845 's Imaging signal processor (ISP) Spectra 280 also has a noticeable boost, with the new ISP focusing more on the quality and color gamut of the paint, giving photos and videos a more accurate, vivid and realistic picture. In addition, Qualcomm pioneered the Ultra HD Premium film recording, capable of filming 4K HDR films, once again leading the film recording technology. It is speculated that with the support of Spectra $number ISP, Snapdragon 840 will be able to record HDR movies with mobile phones with support for HDR displays. In addition, Snapdragon 845 also integrates the new hexagon 685 Digital signal Processor (DSP) to speed up the processing of different workloads, such as AI inference, with relatively low power consumption, which means that the use of Snapdragon 845 handsets can support more AI architectures. In the area of security, Qualcomm uses a completely new independent security module (secure Processing unit), which separates the security features of the Snapdragon 845 mission key from the rest of the SOC, including user passwords, Digital Key Management for application data and other user-sensitive information. Because more mobile subscribers use mobile payments and store user biometric data, Qualcomm does have to improve the processor's level of security protection. In addition, Qualcomm also promotes Snapdragon 845 's networking function. Network connectivity has always been a high throughput processor, Snapdragon 845 integrates its 2nd generation Gigabit LTE Solution Snapdragon X20 LTE data machine, compared to X16 Gigabit class LTE data machine, peak speed 20%, to 1.2 Gbps, Download a 3GB movie can be completed in less than 3 minutes. Snapdragon 845 also uses the new Bluetooth Tru wireless technology to solve a big problem with Bluetooth connectivity, with virtually unlimited connectivity to multiple devices, and for users around many Bluetooth devices, Snapdragon 845 processors will bring convenience. From the Snapdragon 845 renovation of the situation, the mobile phone will be more than the past 1 years to launch the product superior, not only faster processing speed, energy efficiency and overall performance also enhanced, regardless of the implementation of AI functions or visual quality is expected to leap forward, The 2018 market's flagship handset seems to be worth looking forward to.
