During the second day of the summit Qualcomm , the manufacturer has officially announced the release of a mobile platform Snapdragon 855. Chip was the most efficient in the market for flagship devices. The platform has got OCTA core processor which consists of three clusters of nuclei Kryo 485: one consists of a core with a frequency of 2.84 GHz, and the other three cores with a frequency of 2.42 GHz, and the third includes four cores with a frequency of 1.8 GHz.
An integral part of the new platform was also Adreno graphics 640, the signal processor Hexagon 690 and Spectra 380 — a separate processor, which is responsible for image processing. As expected, the new Snapdragon X50 modem support 5G is a separate chip: so the platform is Snapdragon 855 only supports LTE networks with data speeds up to 2 Gbit/s, because in its composition is a modem Snapdragon X24. Why was this done? So even the producers of inexpensive smartphones to use the latest mobile platform Qualcomm refused to support 5G, but at the same time retaining all the advantages S855.
As for performance, Qualcomm said that it has increased by 45 % compared with Snapdragon 845. The performance of the graphics processor at the same time increased by 20 %. 7-nm process technology has allowed to create the highest performing chip, if to take for comparison power rating in watts.
640 GPU Adreno
640 Adreno graphics obviously will be the center of attention for using the platform in game purposes. Qualcomm told that the segment of mobile gaming grows and other platform for video games either “stagnate”, or showing a decline in popularity.
In addition to increasing performance, Qualcomm said a lot about the graphics capabilities of the platform. Graphics Adreno 640 S855 allows you to run real HDR games. The processor supports 10-bit color depth and gamut of Rec 2020 for the use of HDR, and also allows the devices to maintain S855 formats HDR10 + and Dolby Vision, which are the QC standards throughout the world. With Adreno 640 device will be able to maintain 120fps games and without jerks to play videos in the format of 8K (360 degrees).
It is noteworthy that the Snapdragon 855 was the first platform of the company, which is included in the game program Snapdragon Elite Gaming Experience. Here and color correction at the movies, support the Vulkan API 1.1, as well as special algorithms to reduce the frame rate.
Although the new platform does not have a dedicated unit NPU, it could still work with a task for artificial intelligence. These tasks are treated as the GPU and CPU, Hexagon, and other components. All together it represents the fourth generation of the engine AI Engine, the performance of which is three times more than Snapdragon 845.
With the AI Engine Qualcomm also introduced an updated signal processor Spectra 380. It has become more powerful with tricyclic ISP Computer Vision (CV). With the new accelerator Qualcomm wants to use CV-ISP for some graphics tasks because of the energy savings. The company expects that many of the features of the photo will now be available for video: HDR 4K recording at 60 FPS, improved portrait mode and “depth” for the bokeh effect. Power consumption for 4K HDR shooting will be 30% lower than the Snapdragon 845.
Also not without the support of new generations of image files. Currently JPEG is the primary format for photographs taken on a smartphone, but a new S855 will support “files with high image performance” or simply HEIF, which will offer many new features compared to JPEG:
- The size of the images will be 50% less
- HDR support for several color tools
- Data support Computer Vision
- Working with RAW
- Animated photos
- Video data format HEVC
In addition to supporting 5G, the platform will be able to work with Wi-Fi according to 802.11 ay. This will increase the speed of data transfer using wireless connections up to 10 Gbps.
- Codec support aptX Qualcomm Qualcomm Adaptive and TrueWireless Stereo Plus
- The opportunity to work with an ultrasonic fingerprint scanner Qualcomm 3D Sonic Sensor
- Bluetooth Support 5.0
- OpenGL 3.2 and OpenCL ES 2.0 FP
- Quick Charge 4+
- You can use RAM LPDDR4X with a frequency of 2133 MHz
Obviously, the platform Qualcomm Snapdragon 855 will find application in many flagships 2019. Their interest already expressed by Google, Samsung and OnePlus, and then the others will catch up. The main thing — without using 5G the new chip will be available to manufacturers of smartphones in the medium price segment.
