1. Intel still uses the 14nm process. This is because the 14nm process is one of the most advanced Intel processes available and can provide a high performance and energy efficiency ratio. Intel has developed and optimized the 14nm process for many years to make it a reliable and mature process. 3. In addition, upgrading to smaller process nodes (such as 10 nm or 7 nm) requires more capital investment and technical challenges. Intel may choose to continue using the 14nm process to maintain stable production and supply, and to innovate and improve in other areas, such as architecture design and integration technology. This reduces risk and costs while maintaining a certain level of performance, and prepares for future process upgrades.

Intel's processors are stuck at 14 nanometers because the company is going its own way. 14nm-10nm-5nm. The company believes that its excellent chip design can meet product performance requirements at 14nm, and there is no need to cram it into 10nm. In this way, the 14nm wafer line can continue to create value, and the 10nm wafer line is reserved for the top-selling laptop processors.
After entering the 14nm process, intel's factories repeatedly suffered setbacks in advanced process development and lagged behind the semiconductor production plants of TSMC and Samsung. Therefore, the 14nm process did not switch to the 10nm process until the 12th generation Core withdrew.
The primary reason is that Intel 10nm tone is too high, the step is too big, and the difficulty is too high. You see, most people answer this question the same way. The answer is actually wrong. In fact, Intel's 14nm to 10nm range is similar to TSMC's 10nm to 7nm. And when Intel 14nm was just out, Intel was still three years ahead of the industry in the process. Intel's 10nm is two or three years later than TSMC's 7nm. Therefore, Intel's current backward process, basically can not take too big a step on, is a dish.
Intermediate reasons, changes in the semiconductor industry, the rise of mobile computing, and the high input and uncertainty of high-end processes have led to Intel's two fists being difficult to defeat four hands.
Because 14nm chip cost is low, the profit is high.
