The 5-nanometer chip has higher technical requirements, better and lower performance than the 7-nanometer chip. The two values of 5nm and 7nm in the chip process represent the length of the conductive channel of the chip transistor.
Take Apple's 5nm process Apple A14 and 7nm process Apple A13 for example,A14 has 11.8 billion transistors,A13 has 8.5 billion transistors,A14 CPU performance increase of about 16%,GPU performance increase of about 8.3. From the technical point of view of the current chip manufacturing process, the 5nm process is very close to the limit. However, the value of the nanoscale chip manufacturing process can not truly represent the value of the gate width.
