What Is a 5nm Chip, and Why Is 5nm So Important? - How-To Geek
29 Sep 2021Intel 5nm processors are coming too, but it's expected to take a while. The company's desktop processors are expected to come off 14nm and move to 10nm with Alder Lake in late 2021 or early 2022. After that, a 7nm process is expected in late 2022 or 2023, and then in 2024 there could be an Intel 5nm processor .

Anyway Intel 10nm is known to better than TSMC and Samsung 10nm,
However Intel 7nm has high defect rate.

The sign show SMIC though yet to commercialize 7nm in mass , is not far behind Intel.

Only 6 or 7 foundry capable of doing 14nm level.
