However, after entering the process of 10nm and below, Moore's Law has been considered to be a failure. Chip manufacturing is becoming more and more difficult, and the cost is getting higher and higher. It is difficult to double the performance and reduce the cost. But on this issue,IntelAlways firmly defending Moore's Law and not recognizing the problem of failure.

AMD CEO Su Zifeng recently attended the SEMICON West conference and delivered a keynote speech. She mentioned the semiconductor process and Moore's Law. AMD's point of view is in line with Intel's idea that Moore's Law will continue to be useful. But it has slowed down.

Su Zifeng takes CPU and GPU as examples. It points out that the performance of CPU and GPU will probably double every 2.5 years in the past 10 years.

In the performance improvement over the past decade, the process has achieved significant performance improvements, doubling the energy efficiency every 3.6 years and doubling the density every 3 years.

Specifically, 40% of the chip's performance improvement over the past decade is due to processing, 8% from improved TDP, 12% from additional core area, 17% from architectural improvements, and 15% from Power management, and 8% from compiler improvements.

In summary, AMD believes that Moore's Law is still valid, but the speed has slowed down. From the roadmap given by AMD, the 22nm node begins to slow down, especially after the 14nm node.

However, in terms of chip cost, the result is different. The more advanced the process, the more expensive it is, and the trend is becoming more and more obvious.

According to AMD's data, with a core of 250mm2, the cost of the 45nm node counts as 1, 32, 28nm nodes start to increase, 20nm node becomes twice the cost, and the cost of 7nm jumps to 4 times, and the future 5nm is more exaggerated. The cost will be five times that of the previous one.
