12nm and 28nm are two different chip process technologies. Chip process technology refers to the technology used to define the size of transistors and other components on the chip during the manufacture of integrated circuits. Numbers represent the nanometer level of process technology and represent the size of transistors and other components.

The main differences between 12nm and 28nm include:
1. Size difference: 12nm process technology is more advanced than 28nm, and the size of transistors and other components is smaller. This means that 12nm chips can accommodate more transistors and electronic components, providing higher performance and power efficiency.
2. Performance: Due to the smaller size, 12nm chips can achieve higher performance under the same power consumption. They can run at faster clock rates and provide increased computing power and graphics processing.
3. Power efficiency: 12nm chips are more energy efficient than 28nm chips. Smaller transistors can be switched on and off faster, reducing energy waste and thus providing better power efficiency.
4. Cost: Typically, newer process technologies lead to higher manufacturing costs. As a result, 12nm chips may be more expensive than 28nm chips.
5. Application areas: Due to differences in cost and performance, 12nm chips are usually used in high-performance computing, artificial intelligence, game consoles and other applications with high performance requirements. The 28nm chip is mostly used in low-power devices, mobile devices and some traditional embedded systems.
