Love to play computer games On December 6, it was reported that Qualcomm had announced a new generation of mobile platform, Snapdragon 855. Today, the parameters of the processor were disclosed. It is the world's first commercial chip that supports 5G networks, AI, XR and other functions. The performance of Snapdragon 855 is much higher than that of the previous generation products. It has greatly improved in artificial intelligence (AI), photography, video and games, and has advantages over competitors in some aspects.

The CPU of Snapdragon 855 adopts the 7nm process technology. It is Kryo 485 architecture, has eight cores, and uses the combination of 1+3+4. One super core has a dominant frequency of up to 2.84GHz, three performance cores are 2.42GHz, and four efficiency cores are 1.80GHz. The CPU performance of Snapdragon 855 is 45% higher than that of Snapdragon 845. Qualcomm said that using Snapdragon 855 devices to open APP is very fast.

In terms of GPU, the Snapdragon 855 uses Adreno 640, whose graphics rendering speed is 20% faster than the previous generation Adreno 630. Adreno 640 supports Vulkan 1.1 for the first time in the world, and is compatible with OpenGL ES 3.2 OpenCL 2.0 FP， It also supports HDR games, up to 4K HDR display, and 8K 360 VR video playback.

Snapdragon 855 supports LPDDR4X 2133MHz memory, which can reach up to 16GB like Kirin 980. In terms of baseband, Snapdragon 855 has built-in X24 Modem, peak 2Gbps rate, LTE Cat.20， It is a 7nm process, and another 14nm process RF chip is used. If the mobile phone equipped with Snapdragon 855 wants to support 5G network, it must have an external Snapdragon X50 baseband. Snapdragon 855 is the world's first WiFi 6, and also the world's first processor supporting 60GHz WiFi, with a peak speed of 10Gbps.

This new processor also uses the fourth generation AI Engine, a multi-core engine with more than 7 trillion operations per second (7TOPs). Qualcomm said that its AI performance was three times higher than that of Snapdragon 845, and twice as high as that of competing Android platforms that also use 7nm. The Snapdragon 855 also has a built-in Hexagon 690, which, in addition to being a DSP, also implements some NPU functions, and has a built-in tensor accelerator designed by high pass for AI operations.

The Snapdragon 855 has a built-in Spectra 380, which is the world's first computer vision ISP. It supports parallel dual cameras with 22 million pixels and 30 fps, or a single camera with 48 million pixels and 30 fps. In addition, it supports shooting high frame rate slow motion video, up to 720P/480fps.

Snapdragon 855 also supports Qualcomm 3D acoustic sensor, which is the world's first commercial solution to support ultrasonic fingerprint under the screen. At present, only this solution can penetrate multiple stains for accurate fingerprint identification.

From the first half of next year, many mobile phone manufacturers will adopt Snapdragon 855 as their flagship products, including Xiaomi, Yijia, Samsung, etc.
