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.
- tiffanyh 1y agoThis 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 https://news.ycombinator.com/item?id=27063034 https://news.ycombinator.com/item?id=27063034 https://www.techradar.com/news/ibm-unveils-worlds-first-2nm-chip https://www.techradar.com/news/ibm-unveils-worlds-first-2nm-...
- cherioo 1y agoI 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/7_nm_process https://en.m.wikipedia.org/wiki/2_nm_process https://en.m.wikipedia.org/wiki/2_nm_process
