The main difference lies in the manufacturing process and performance. 28 nanometers is an older manufacturing process, which refers to the minimum feature size (transistor gate width) used in the chip manufacturing process as 28 nanometers. 5nm, on the other hand, is a newer manufacturing process that uses a minimum feature size of 5nm, which is smaller than 28nm. This means that 5nm chips can have more transistors in a smaller space, providing higher performance and lower power consumption.
Specifically, a 5-nanometer chip can achieve higher clock speeds and higher processing power than a 28-nanometer chip. At the same time, due to the increase in the number of transistors and higher energy efficiency ratio, 5nm chips can also provide longer battery life and better energy saving performance. In short, the 5-nanometer chip is a more advanced and higher performance chip manufacturing process that is expected to drive the development of the technology industry in the future.
The main difference between the 28-nanometer chip and the 5-nanometer chip is the difference in manufacturing process - that is, the transistor size of the two chips is different. 28nm (28nm) and 5nm (5nm) are the nanoscale processes used to make chips, with 28nm being the earlier process and 5nm being one of the most advanced.
There is no essential difference between 28nm and 5nm chips, but different scenarios have different requirements for chips, and those who pursue stronger performance, or products with size and energy consumption limitations tend to pursue more advanced processes, but this approach tends to cost more.
Those scenarios that are not so high in performance requirements and are not sensitive to size energy consumption tend to use older processes, after all, this is more cost-effective.

The 28nm and 5nm chips have two main different characteristics:
< br >
One is the size: the 28nm chip is eight times larger than the 5nm chip due to the large size of the transistor.
< br >
The second is performance: the 5nm chip has a higher transmission rate than the 28nm chip, can support higher processing efficiency, and play a higher performance. At the same time, 5-nanometer chips are more power-efficient than 28-nanometer chips, provide higher chip density, are smaller, and consume less power.
The difference between the 28-nanometer chip and the 5-nanometer chip is mainly that the computing power is different, the volume is different, and the energy consumption is not the same.
The smaller the production process of the chip, the stronger the computing power, the smaller the size, the 28 nanometer chip belongs to the chip of the medium production process, the larger the volume, the computing power is weaker than the five nanometer. The five-nanometer chip belongs to the advanced technology chip, the size is relatively small, the computing power is strong, and the energy consumption is reduced.
The essential difference between 28nm and 5nm is the transistor width, when the transistor is smaller, the chip of the same size can accommodate more transistors, 7nm era, the number of transistors of the chip is about 700,000, and to the 5nm era, it can be done 12 billion or even 15 billion transistors (Kirin 9000 is 15.3 billion transistors), Therefore, the improvement of the process technology is very intuitive to improve the performance. And the smaller the width of the crystal pipeline, the less energy consumption.
Either 28nm chip or 5nm chip is a large-scale semiconductor integrated circuit, so in essence there is no difference between the two. The biggest difference is the size of the accuracy.
However, the 5nm process can put more collective tubes per unit area, and according to Dennard's law of scaling, as the transistor density increases, the power consumption per transistor decreases. For example, if the area of the transistor is halved and the frequency remains unchanged, the power consumption of the transistor will be reduced to a quarter of the original. The decrease in energy consumption can directly lead to the reduction of heat, which in turn brings space for the improvement of frequency, which can naturally bring about the improvement of performance.
