Don't forget 12 nm is still the best Intel can fab, it might not be world class currently but it's certainly very capable. Imo it's very threatening, especially if they also keep grabbing talent like they seem to be capable of doing.
There is no standard comparison because of different architectures.
that's crazy, and news to me. So now a unit of length is a marketing term. This is even more misleading than branding the word "real" so you can advertise "contains Real(tm) cheese" on food products.
I think it comes down to what feature length you are measuring. Transistor density seems like a better measure.
Intel has 10nm fabrication, which is equivalent to TSMC’s 7nm
10nm Intel CPUs exist. I have seen them with my own eyes. Reading the tea leaves from public statements and articles like that, the yields seem to be crap right now.
I am typing this reply from a Lenovo Thinkbook 14-IIL, that has a 10nm CPU, also known by its codename Ice Lake. It's not a desktop CPU, it's a mobile CPU, but it's enough to counter your claim that "Intel doesn't yet have 10nm".
