Chip process refers to the line width of the gate in the transistor structure, which is the value in the nanometer process, the narrower the width, the lower the power consumption.
Generally speaking the chip 14nm, 10nm, 7nm, 5nm, refers to the chip's process technology, that is, the size of the transistor gate circuits on the surface of the CPU and GPU within the processing. Generally speaking the more advanced the process, the smaller the transistors are, so the more transistors can fit on the surface of a chip of the same size, and the stronger the performance.
With the development of chip technology, the chip process has been able to do 2nm, but this is the data in the laboratory, specific to the mass production process, the countries are not the same. Currently the most advanced mass production process is 5nm, China Taiwan's TSMC, South Korea's Samsung Electronics have launched the relevant technology to achieve mass production shipments.
Introduction
The chip process from the initial 0.35 micron to 0.25 micron, and later to 0.18 micron, 0.13 micron, 90nm, 65nm, 45nm, 32nm and 14nm. in the process of improving the chip process process, the geometric dimensions and power consumption need to be reduced by a factor of about ten.
Theoretically, many factors come into play in the process steps. At 7nm, for example, smaller geometry means more transistors per square millimeter, which means higher density, clocks, thermal design power consumption, and lower transistor voltage.
