When choosing a CPU, both 7nm and 8nm have their own advantages. The 7nm process is more advanced than 8nm, with higher integration and lower power consumption. This means that a 7nm CPU can provide better performance and efficiency at the same power consumption. However, the 8nm process is relatively mature, has lower production costs, and may be easier to achieve high frequency and stability. So which one is better depends on your needs.
If you're after the most advanced performance and power efficiency, 7nm is the better choice. If you're more concerned about cost and stability, 8nm might be right for you.
The CPU process refers to the size of the transistor on the chip, and 7nm and 8nm are common process processes at present. In general, the smaller the process, the smaller the transistor, the lower the power consumption, and the better the performance. Therefore, the 7nm process has more advantages in terms of performance and power consumption than the 8nm process. However, the process is not the only determining factor, and factors such as architectural design, number of cores, frequency need to be considered. Therefore, the selection of cpus needs to consider all aspects of the factors, not just limited to the process.
