Snapdragon 855 Review:
anandtech recently made a detailed evaluation of Snapdragon 855:
1. CPU: Compared with Kirin 980, the memory delay is higher, but the overall CPU performance is still slightly higher than Kirin 980, SPECint2006 performance increased by 51% compared with 845, CPU energy efficiency increased by 39% compared with 845, SPECfp2006 compared with 845 is increased by more, reaching 61%. Compared to the Kirin 980, respectively, 4% and 9%, although the highest core reached 2.85GHz, but the energy efficiency is still very good.
2. AI: Due to the blessing of Hexagon 690, AI performance has been greatly improved compared with 845, which is about 2.5-3 times the AI performance improvement of 845;
3, application: the system application performance is not great, stronger than 845, but weaker than 980, the official said that it may be the relationship between the scheduling Settings on the engineering machine, and the formal commercial equipment will be improved.
4. GPU: In terms of peak performance of Adreno 640 GPU, the gap is still obvious compared with A12, but the energy efficiency ratio is good. The average power consumption of GFXbench3.1 off-screen rendering is 4.44W. In terms of energy efficiency, the peak state of A12 is 17.36fps\/W, the frequency reduction state is 20.18fps\/W, and the 855 is 16.05fps\/W. 845 is 11.99fps\/W, 980 is 11.93fps\/W, the overall energy efficiency ratio increased by 30% compared with 845;

Snapdragon 855 processor first-class. The Qualcomm Snapdragon 855 processor uses an 8-core architecture of 1, 3, 4 and is built based on a 7nm process. It uses the Qualcomm Kryo 485 CPU based on Arm Cortex technology, which can deliver up to 45% performance improvements compared to the previous flagship platform. In addition, the new Qualcomm Adreno 640 GPU can deliver up to 20% faster graphics rendering.
I use Snapdragon 855 processor, performance is very good, this processor is a high score company independent research and development of a processor, by TSMC foundry production, equipped with the flagship models of various mobile phone manufacturers, and has a good reputation Snapdragon this company in recent years in mobile phone processing is actually occupied half of the country. My asshole is helping you.
This processor in 2018 is the flagship level of the processor, its Antu running points can reach nearly 400,000, he is Samsung's ten-nanometer process, but many Android flagship mobile phones have used this processor, and then put in today's words, this processor is outdated, because it does not support 5G dual-mode full Netcom function.
The Qualcomm Snapdragon 855 is a mobile processing platform produced by Qualcomm. The Snapdragon 855 is the world's first commercial 5G mobile platform.
Using TSMC 7nm process, the CPU uses eight-core Kryo? 485 architecture, compared with the Snapdragon 845 CPU performance improvement of about 45%, GPU using Adreno? 640, compared with the previous generation of products graphics rendering capacity increased by about 20%. Commercial launch in the first quarter of 2019.
