Last I heard they hoped to get their 6nM process running in 2021.Then I'd say they are ahead of Intel (7nM) and US based fabs AFAIK. When I left the semi biz 19 years ago, TSMC was working on dialing in their [9nM process. ](https://www.eetimes.com/tsmc-describes-new-transistor-type-to-enable-9-nm-chip-designs/) I've been talking about how far behind Chinese semiconductor tech is compared to USA and Taiwan's TSMC.
