Qualcomm Snapdragon Technology Summit yesterday, Qualcomm announced a new generation of flagship mobile platform Snapdragon 845, and said it in the shooting, AI, performance, security and other six major areas have greatly improved now come to the summit the next day, Qualcomm Announced more details about the Snapdragon 845.
Qualcomm said the Snapdragon 845 with a new Kryo CPU architecture (Kryo 385) and incorporates a new GPU unit Adreno 630, compared to the Snapdragon 835, Snapdragon 845 graphics processing speed increased by 30%, energy efficiency increased by 30%, to further extend Mobile phone life.
Based on Samsung's second generation 10nm process, the new Kryo 385 includes four performance cores running at up to 2.8GHz (25% -30% performance improvement over the previous generation), four efficiency cores running at 1.8Ghz (15% increase), the other Snapdragon 845 also added 2MB shared L3 cache and 3MB system cache.
In image processing, the Snapdragon 845 incorporates the new Spectra 280 ISP video signal processor, while also integrating a more powerful Hexagon DSP, so that machine learning and AI applications significantly improve the performance.
The new ISP supports shooting HDR 4K @ 60fps video for the first time in a smartphone, followed by HDR 720P @ 480fps super slow motion video capture, active depth sensing, and more advanced portrait modes. Yes, Qualcomm said the phone using Snapdragon 845 DxOMark shooting score can reach 100 points or more.
Security, Snapdragon 845 integrated a separate security processing unit, which can perform task verification or key verification independent of the main processor, that is more difficult to hackers crack.
In connection, the Snapdragon 845 integrates the latest X20 LTE baseband with 5x carrier aggregation, peak download speeds of up to 1.2Gbps and up to 20% over X16. The X20 also supports dual LTE SIM mode, dual SIM dual standby More practical.
Wi-Fi performance has also been enhanced, not only to enhance the initial connection settings, while energy efficiency has also increased by 30%. Bluetooth, the Snapdragon 845 supports simultaneous broadcast to multiple Bluetooth devices, Qualcomm said it will have the development of wireless headsets big influence.
