Qualcomm's next-generation flagship mobile platform, the Snapdragon 855, is manufactured in a 7nm process, integrating eight Kryo CPU cores (one Kryo 485 super core + three performance cores + three efficiency cores), Adreno 640 GPU graphics core, Hexagon 690 DSP digital signal processor, Spectra 380 ISP image signal processor, Snapdragon X24 2Gbps high-speed baseband and other modules, added a tensor accelerator for AI and supports the fourth generation AI engine.

Qualcomm claims that the performance of the Snapdragon 855 CPU is 45% higher than that of the previous Snapdragon 845, which is the largest in the past. At the same time, the GPU performance is increased by 20%, and the AI ​​performance is increased by 3 times, which is higher than the competitors. Doubled.

In addition, the Snapdragon 855 can also be connected to the 骁龙X50 baseband and QTM052 millimeter wave antenna module to realize 5G mobile phones. Many manufacturers will realize commercial use in the first half of next year.

So, what is the actual power consumption of Xiaolong?

At the scene of the Dragon Technology Summit in Hawaii, Qualcomm also deliberately conducted a field demonstration on this face. Faced with a Snapdragon 845 mobile phone, and a Snapdragon 855 reference design prototype, all with 3000mAh battery , the network is connected to Wi-Fi.

In the first game of eating chicken, the average power consumption of Xiaolong 845 mobile phone is about 3280mW, and the prototype of Xiaolong 855 is only about 2580mW. It was reduced by about 21%, which extended battery life by 1 hour to 27%.

Secondly, in daily applications, the simulation video is captured and uploaded to Instagram. The average power consumption of the 骁龙 845 mobile phone is about 2240mW, and the prototype of the 骁龙 855 is only about 1785mW, which is about 20% lower. This battery life is also nearly one and a half hours long, up to 25%.
