Three generations
First of all, nm refers to the manufacturing process of integrated circuits on the circuit board, which means twenty-eight nanometers, while 7nm is the seventh nanometer
The smaller the number of nanometers of the manufacturing process, the higher the algebra
Therefore, the difference between nm and 7nm three generations of
high algebra manufacturing process has brought significant technical advantages. Such as higher integration, lower power consumption and better performance, many leading semiconductor manufacturers are now developing 7nm and below processes to provide more advanced products
If it refers to the mobile phone chip, there is 14nm between 7nm and 28nm, which is a difference of two generations.
28nm is seen as the dividing line between advanced and mature semiconductor processes.
The 7nm chip process is the world's first echelon technology.
