The 7nm process has better performance and power consumption than the 14nm and 10nm processes.
In the field of chip making, the nanometer represents the distance between transistors in the chip and the transistor, in the case of the same size, the number of transistors in the 7-nanometer process chip is almost twice that of the 14-nanometer process chip. The number of crystals in the chip determines the strength of the chip's performance, in other words, the more transistors in the chip, the stronger the ability to process transactions, the stronger the performance of the chip. The 7-nanometer chip is smaller and consumes less power than the 14-nanometer chip when the function is the same.
