Why doesn't the Zen4 processor go on the 3nm process? AMD response: 5nm is the most appropriate

At last week's CES show, AMD unveiled parts of the 5nm Zen4 processor for the first time, supporting DDR5 and PCIe 5.0, upgrading the AM5 socket, and designating it as the Ryzen 7000 series, which will be available this year.

Zen4 architecture will use TSMC's 5nm process, which is still the main force of TSMC, but in 2022, 5nm is obviously not the most advanced process, TSMC not only has a 4nm process, this year will also mass-produce 3nm process.

In the same industry, Apple has used the 5nm process for more than two years, why should AMD lag behind so much before going to the 5nm process, instead of following up the 3nm process for the first time?

For this question, AMD CEO Su Zifeng said that AMD will complete certain tasks based on its own technical process, and for the Zen4 architecture, the 5nm process is the most suitable choice, because the process is optimized for high performance.

Previously, AMD CEO Su Zifeng also confirmed that Zen4 uses a special version of the 5nm process, which is not necessarily the same as the 5nm used by other companies, but AMD did not disclose the specific technical details of Zen4's 5nm.
