Currently, 4-nanometer chips have the most potential.
The most potential chip in the world does not exist, and a single chip can only be eliminated by later comers, because the chip design can be optimized. A chip performance again powerful, according to Moore's Law 18 months will be born than his performance. So it's not the chip that has the potential, it's the process. At present, the most potential chip process in the world is the 4-nanometer process, which reached mass production at the end of last year, and after TSMC and Samsung temporarily abandoned the 3-nanometer process, the 4-nanometer chip process has become the most potential chip process.
