The 5Nm chip is used as follows.
At present, the world's most high-end chips are used on mobile phones, because it is necessary to meet the strongest performance in a very small space, so 5Nm chips are mainly used for mobile phone chips and some other chips, such as 5g baseband in mobile phones. There are also many devices that need to use powerful chips, such as supercomputing, etc., but because there are not too many space constraints plus cost and performance factors, computer chips have not developed a higher process than mobile phone chips, so the vast majority of 5Nm and above process chips are used in mobile phone communications.
