1 nanometer chip means double the performance of the chip.

Chip technology is currently based on Western-led technical indicators, which follow Moore's law, that is, the number of transistors that can be accommodated on an IC will double every 18 months, and its performance will also double, according to this theory, the smaller the chip process, the more transistors can be loaded per unit area. Therefore, the chip with a smaller process theoretically has better theoretical performance, so it can be seen that the performance of the 1nm chip is about 1458 times higher than that of the most high-end 5nm chip commonly used now, and it is easy to know how high its computational efficiency is.
Push the limits of physics. The diameter of silicon atoms is almost 1nm, if less than 1nm means that the line width can be made even less than an atom, which has exceeded the physical limit of human operation.
However, the possibility of changing the base material at 1nm is not ruled out.
