CPU how many nanometers refers to the line width of the chip manufacturing process, also known as the process node. A nanometer is a unit of length, with 1 nanometer equal to a billionth of a meter. Therefore, the smaller the number of nanometers of the CPU, the more advanced the manufacturing process, the more transistors on the chip, and the better the performance.
For example, a CPU manufactured by a 14nm process can provide higher performance and lower energy consumption at the same power consumption compared to a CPU manufactured by a 28nm process. Cpus manufactured by the 7nm process further improve performance and energy efficiency. Therefore, the advancement of chip manufacturing process is also an important driving force for CPU performance improvement.
CPU number of nanometers refers to the size of the chip manufacturing process, that is, the size of the transistor. A nanometer is a unit of length, and 1 nanometer is equal to 10 to the minus nine meters. With the continuous progress of the manufacturing process, the smaller the number of nanometers of the CPU, the smaller the size of the transistor, and more transistors can be integrated in the same chip area, thereby improving the performance and power efficiency of the CPU.
Generally speaking, the smaller the number of nanometers, the faster the processing speed of the CPU, the lower the power consumption, but the higher the manufacturing cost. The current CPU on the market mainly has a variety of nanometer numbers such as 14 nm, 10 nm, 7 nm.
