Qualcomm Snapdragon 845 to ship in first devices in early 2018

Thursday 7 December 2017 | 08:38 CET | News

Qualcomm Technologies has released more details on its new flagship smartphone processor, the Snapdragon 845. The chip is now sampling with customers, and the first devices running the processor will launch in early 2018. 

The Snapdragon 845 was designed to support new applications such as capturing 4K video and virtual and augmented reality, while not draining the power or performance of the device. The platform includes an integrated Qualcomm Spectra 280 image signal processor and Qualcomm Adreno 630 visual processing subsystem to support "cinematic video capture, along with superior photography" on flagship mobile devices. 

The Snapdragon 845 will be able to captures 64x more high-dynamic range color information for video capture and playback on Ultra HD Premium displays, compared to the previous generation. It is also the first mobile platform to enable room-scale 6 degrees of freedom (6DoF) with simultaneous localization and mapping for features such as wall-collision detection. Additionally, Snapdragon 845 introduces Adreno foveation, which substantially reduces power consumption, improves visual quality and boosts VR/AR application performance, Qualcomm said.

The Snapdragon 845 also delivers 3x improvement in overall AI performance versus the prior generation, to support applications such as digital assistants, and the Qualcomm Aqstic audio codec (WCD9341) offers low-power voice processing and improved keyword detection for voice commands on the phone. Qualcomm also optimised the platform for Google, Android and Facebook development frameworks, under the Snapdragon Neural Processing Engine. 

For improved security, to protect personal data such as mobile payment transactions, the Snapdragon 845 introduces a hardware isolated subsystem called the secure processing unit, which is designed to add vault-like characteristics to existing layers of Qualcomm Technologies’ mobile security. Doing so makes it possible for improved biometrics security used for authentication, as well as user or application data key management used to encrypt critical information, Qualcomm said. 

On the connectivity side, the Snapdragon 845 will come with the X20 LTE modem with support for LTE Category 18 at up to 1.2 Gbps, up to 5x carrier aggregation, License Assisted Access, dual SIM-dual VoLTE as well as 4x4 MIMO on up to three aggregated carriers. The modem also supports an expanded range of frequency band configurations across licensed, unlicensed and shared radio spectrum, to accelerate global availability of gigabit LTE as operators prepare for 5G. 

In addition, it delivers diversity-enhanced 60GHz 802.11ad Wi-Fi for more robust coverage at speeds up to 4.6 Gbps, and integrated 802.11ac Wi-Fi with advanced features that provide up to 16X faster connection setup, simultaneous dual-band support and 30 percent more capacity utilization on carrier Wi-Fi networks, compared to the previous generation.
