I am curious where you get your information about Samsung being more “precise”.

I was recently looking into 2nm myself, and based on wikipedia article on 2nm, TSMC 2nm is about 50% more dense than the samsung and intel equivalent. They aren’t remotely the same thing. Samsung 2nm and Intel 18A are about as dense as TSMC 3nm, that’s been in production for years.

This information is a bit dated but ...

Since "nm" is meaningless these days, the transistor count/mm2 is below.

As reference: TSMC 3nm is ~290 million transistors/mm2 (MTr/mm2).

             IBM      TSMC   Intel   Samsung
  22nm                       16.50  
  16nm/14nm          28.88   44.67   33.32
  10nm               52.51  100.76   51.82
  7nm                91.20  237.18   95.08
  5nm               171.30    
  3nm               292.21    
  2nm        333.33

		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

I did the math on TSMC N2 vs Intel 18A, and the former is 30% denser according to TSMC
