Even if it was, it wouldn't have been the world's first 2nm mobile chip. Google unveiled the Pixel 11 series smartphones a couple of days ago, with the...
I’m not in the field but my understanding is the various companies measure it slightly differently because of difficulty measuring on a nm scale. Also not all transistors are the same. Plus you can do a lot of other work which makes it faster than just shrinking the transistor size. Similar to cpu being much faster today then they were in 2015 despite having a similar clock rate(maxing out at between 3.5-4.5 ghz). Stuff like improved branch prediction, better use of simd, improvements in the address translation layer.
I’ll try to find a article but a lot of the inner details are nit made public.
