The 5nm chip is the process standard of the chip, and the Qualcomm Snapdragon chip is the designer of the chip, and these two words are not comparable. Qualcomm is the world's largest mobile phone chip designer, Snapdragon chip is its signature processor, respectively, the flagship 8 series processor, the sub-flagship 7 series processor, the flagship 6 series processor, and the entry-level 4 series processor. Snapdragon 888 is Qualcomm's flagship processor just out this year, with a 5nm process.
The five-nanometer chip is of course the Kirin chip, which is better than the Qualcomm chip. Because the Kirin 9000 uses TSMC's five-nanometer technology layer process, and the Qualcomm Snapdragon 880 uses Samsung's five-nanometer process, obviously the performance of Qualcomm Snapdragon 888 is better than the Kirin 9000, but the stability and power consumption of the Kirin 9000 are better than the Qualcomm Snapdragon 88
