Qualcomm held an extended presentation of the flagship Snapdragon 855 mobile chipset, which was announced during the first day of the Tech Summit technology conference. The novelty has become the world's first mobile 5g platform with high data transfer speed, advanced artificial intelligence functions, and significantly improved multimedia capabilities.
The official specifications of the top 7-nm processor confirmed the previously published information. The eight Kryo 485 cores are divided into three clusters: a large 2.84 GHz core, three high-performance (2.42 GHz) cores, and four 1.8 GHz energy-efficient cores. CPU performance increased by 45% compared to Snapdragon 845. Increase the power of GPU Andreno 640 of its predecessor was 20%. Supported memory LPDDR4X with a frequency of 2133 MHz.
Serious changes had been made to the ability of an artificial intelligence platform. Engine AI Engine 4th generation uses the hardware power of the GPU and the auxiliary processor Hexagon 690. Its overall performance is more than 7 trillion operations per second — three times that of the previous generation.
The new Qualcomm Spectra 380 image processor uses AI algorithms to classify and track objects in the frame, including motion, both in the real world and in augmented reality applications. Installation of a single camera module with a resolution of 48 MP or dual with sensors of 22 MP is supported. Artificial intelligence is able to improve the image using filters and adjust autofocus, as well as post-processing of finished frames on the fly.
The advanced voice assistant can cut off echoes and extraneous noise, distinguishing the voice of the device owner even on a busy street or stadium. The computer vision feature enables hardware depth detection when shooting 4K video at 60 frames per second. The user will be able to edit the video directly during its creation — for example, it will be possible to use the bokeh effect or replace the background in the frame of the future movie.
For the first time for mobile devices support of the HDR10+ standard both for playback and for video recording is declared. Hardware acceleration of decoding and decoding of H. 265 and VP9 will provide high energy efficiency when playing multimedia files. Switching to hardware processing of multimedia files also significantly increases the energy efficiency of the platform.
Especially for high-resolution content storage, support for the HEIF file format has been implemented, providing up to 50% disk space savings due to high compression efficiency at the best picture quality. Unlike JPEG, HEIF works not only with individual photos but also with groups of images and animated images.
The platform's wireless capabilities are represented by a 5g Snapdragon X50 modem operating in the 6 GHz and mmWave frequency bands, as well as a 4G Snapdragon X24 module for compatibility with previous-generation networks. The modem has enough bandwidth to handle virtual and augmented reality up to 8K resolution and real-time video processing. The maximum download speed in the 5g coverage area can reach 5 Gbit/s, in LTE networks — up to 2 Gbit / s.
"As operators launch 5G networks in early 2019, consumers will be able to take advantage of the new technology on mobile devices with Snapdragon 855. We're proud to share our technological inventions and become one of the first to bring 5G mobile connection in the world," said Alex Katouzian, Senior Vice President and Managing Director of mobile technology Qualcomm Technologies.
Snapdragon 855 has received support for Wi-Fi standard 6 ready and MIMO technology for more efficient use of a large number of devices within the range of the access point. It is the first mobile platform to support 802.11a with wireless speeds of up to 10 Gbps with low latency.
Audio capabilities of the chipset are represented by Qualcomm TrueWireless Stereo Plus technology for wireless headphones, which optimizes signal delay between the right and left channels and reduces power consumption. This will significantly increase the time to listen to music from a single battery charge when using True Wireless devices.
A separate speech of the company's representatives was devoted to the gaming capabilities of the new platform.
Currently, Qualcomm is already in talks with vendors. Oneplus CEO Pete Lau confirmed that the company will be the first to release a 5G smartphone early next year. It is expected that mass deliveries of Snapdragon 855 for commercial devices will begin in the first half of 2019.
