I think the intel 7nm is unrealistic. If true intel wouldn’t be “behind”

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
