5 nm chip is the chip minimum composition gate width of 5 nm.
The 5-nanometer chip means that the minimum gate width of the chip to form a silicon transistor is 5 nanometers, which is close to the physical width of the atomic level. In the case of Apple's a15 chip manufactured by TSMC, the chip contains 17 billion silicon transistors, that is, 170 million silicon transistors per square millimeter, and Samsung's chip has reached 150 million silicon transistors per square millimeter.
5 nanometers refers to the width of the transistor, the smaller, under the same face, have more transistors, while the performance will be greatly improved, power consumption is reduced. The 5nm process is 30% more energy efficient and 15% better than the 7nm process.
Mobile phone chip 5 nm is very, very small, is a very leading technology, the current best company in China SMIC can produce 14 nm
