Since "nm" is meaningless these days, the transistor count/mm2 is below.
As reference: TSMC 3nm is ~290 million transistors/mm2 (MTr/mm2).

According to Wikipedia intel 7nm density is ~62 MTr/mm2. I cannot find the source wikichip page mentioned in your reference post.
FWIW, I am not in the semi industry and all my info are from Wikipedia https://en.m.wikipedia.org/wiki/7_nm_process https://en.m.wikipedia.org/wiki/2_nm_process
