Unit (SPU). According to Qualcomm, the Snapdragon 845 is already the third-generation AI computing platform of Qualcomm, which is three times more powerful in terms of AI performance than the previous generation.
Qualcomm explains the five aspects of immersive experience, AI, connectivity, security and performance.
First from the immersive experience, Qualcomm said that the Snapdragon 845 can enable consumers to capture film-level video and break the boundaries between reality and the virtual world. The Snapdragon 845 integrates the Qualcomm Spectra 280 ISP and the Qualcomm Adreno 630 vision processing subsystem. These new architectures deliver high-performance, true-to-life cinematic video capture for flagship mobile devices.
Compared with its predecessor, the Snapdragon 845 can capture up to 64 times of high dynamic range color information to support video capture and playback on the Ultra HD Premium display, while its predecessor is also the first mobile industry to support Ultra HD Premium. The platform for content playback. Can support the Rec.2020 wide color gamut display, which can be displayed in 1 billion shades of color.
In addition to the increased video capture experience, the new Adreno 630 vision processing subsystem architecture delivers immersion and intuitiveness, providing innovation for new XR experiences including VR, AR and MR.
According to Qualcomm, the Snapdragon 845 is the first mobile platform to support room-scale six-degree-of-freedom (6DoF) and instant location and map construction (SLAM).
AI: The third generation artificial intelligence platformIn terms of artificial intelligence (AI), Qualcomm said that Snapdragon 845 is the third generation AI mobile platform of Qualcomm Technologies. Compared to previous generation system-on-chip (SoC), the Opteron 845 brings nearly three times the overall performance improvement of AI.
The Snapdragon 845 uses the Qualcomm AqsTIc audio codec (WCD9341) and a low-power audio subsystem with outstanding power consumption to enable enhanced always-on keyword detection and ultra-low-power speech processing, optimizing voice-driven smart assistants, thereby enabling Users can interact with the terminal through voice at any time throughout the day.
Security: safe like a vaultIn terms of security, the Snapdragon 845 introduces a hardware isolation subsystem, the Secure Processing Unit (SPU), which hopes to add security features such as vaults to the existing layers of the mobile security solution, thereby enhancing biometric authentication security and users. / Application data key management to encrypt important information.
Connectivity: Peak download 1.2GbpsIn terms of connectivity, the Opteron 845 integrates Qualcomm's second-generation Gigabit LTE solution, the Opteron X20 LTE modem. Download a 3GB movie within 3 minutes before boarding. Accelerate the global application of Gigabit LTE when operators prepare for 5G. The modem supports Category 18 LTE peak download speeds up to 1.2 Gbps, up to five carrier aggregation, licensed assisted access (LAA), dual card dual VoLTE, and 4x4 MIMO on up to three aggregated carriers.
The Snapdragon 845 also supports advanced 60 GHz 802.11ad Wi-Fi, adding support for diversity antennas for a more stable multi-gigabit network experience at speeds up to 4.6 Gbps; and integration with advanced features of 802.11ac Wi -Fi, up to 16 times faster connection setup speed than previous generations.
In addition, Bluetooth 5 can reduce power consumption of wireless earbuds by up to 50% compared to previous generations.
With a new imaging and visual processing architecture, the Opteron 845 reduces power consumption by up to 30% in video capture, gaming and XR applications (compared to previous generations). The Adreno 630 architecture can increase image performance and energy efficiency by up to 30% (compared to previous generations). The new Qualcomm Kryo385 architecture, built on Arm Cortex technology, delivers up to 25% performance gains in games, application startup times and heavy-duty programs (compared to previous generations).
According to reports, commercial terminals equipped with the platform are expected to begin shipping in early 2018. The Snapdragon 845 will support terminals including mobile phones, XR headsets, and always-on PCs. Xiaomi Leijun has made it clear that Xiaomi 7 will carry the chip.
