There are multiple series of Snapdragon.
(1) Snapdragon 14nm processors include Snapdragon 626, Snapdragon 427, Snapdragon 653 and so on.
Snapdragon 626 is an octa-core A53 architecture, Snapdragon 427 is a quad-core A53 architecture, and Snapdragon 653 is a quad-core A73 quad-core A53 architecture: 2. Since the A53 is the core of low performance and low power consumption and the A73 is the high-performance core, there is no doubt that the Snapdragon 653 is positioned in the high-end, while the Snapdragon 626 is positioned in the low-end: 3. The Snapdragon 626, which is positioned at the low-end, uses a more advanced 14nmFinFET process. More advanced processes can achieve better performance and lower power consumption, and the A73 core used in the Snapdragon 653 needs to use more advanced processes to reduce power consumption and improve performance
