3nm chips can achieve more performance with less space.
The 3nm chip is the chip in the mass production stage of Samsung and TSMC, and its transistor density is as high as 300 million per square millimeter. At present, the highest process of 4nm chips on the market is about 170 million per square millimeter, and the transistor density of 3nm chips has increased a lot, and its computing power has also increased a lot. The computing power of a chip is mainly determined by the number of transistors. At present, high-process chips like 3nm are basically used in mobile devices, because space is limited, and the chip process must be improved to obtain more computing power.
