The 4nm chip, which is what this chip is made of, is 4 nanometers. The trend of the process technology is to develop in the direction of higher density. The higher the density of the IC circuit design, means that in the same size area of the IC, you can have a higher density, more complex function of the circuit design. The development and progress of microelectronics technology is mainly based on the continuous improvement of process technology, which makes the feature size of the device continue to shrink, so that the integration degree continues to improve, the power consumption is reduced, and the device performance is improved.
The 4nm chip refers to the gate width (also known as gate length) of the CMOS field-effect transistor formed on the CPU as 4nm.
The smaller the nm, the more advanced manufacturing process, the more advanced manufacturing process can make the CPU and GPU internal integration of more transistors, so that the processor has more functions and higher performance; More advanced manufacturing processes will reduce the thermal design power consumption (TDP) of processors, thus solving the barrier of processor frequency increase.
