The difference is large, and the improvement of 3nm chips relative to 7nm chips is significant.
First, the 3nm process node is smaller than 7nm, meaning that the transistor density is higher and more transistors can be accommodated in the same chip area. This will result in higher performance and lower power consumption.
Second, the 3nm process uses more advanced materials and technologies, such as higher transistor dimensions and lower resistance, which provides faster clock speeds and higher frequencies.
In addition, 3nm can provide better energy efficiency, extended battery life, and better support for artificial intelligence, Internet of Things, and other high-performance applications.
In short, the improvement of 3nm over 7nm will lead to higher performance, lower power consumption and a wider range of applications.
