Silicon lattice step is ~0.5nm, so 1nm is at most 3 atoms. Current technology is definitely not there yet however we're getting closer. Very interested what marketing department will say after 1nm became old news
The term "5 nanometer" has no relation to any actual physical feature (such as gate length, metal pitch or gate pitch) of the transistors. It is a commercial or marketing term used by the chip fabrication industry to refer to a new, improved generation of silicon semiconductor chips in terms of increased transistor density, increased speed and reduced power consumption.
It is an industry standard term for describing a process node which is quite different from marketing bullshit.
• 480p/480i, SD
• 720p/720i, HD
• 1080p/1080i, full HD, 2K*
• 2160p, ultra HD, 4K*
* actually refers to several resolutions with different aspect ratios, but roughly the same pixel count
But definitely there is nothing 4000 about it, it's 3840 by 2160, about 8.3 megapixels.
Just because all of the marketing departments choose to participate in this particular bs doesn't mean it's not pure marketing bs. That just means it's industry standard marketing bs.
How Are Process Nodes Defined?

> The numbers that we use to signify each new node are just numbers that companies pick.
By TSMC standards, Intel's 7nm is a 5nm process and Intel's 10nm is a 7nm process.
So it is not even industry standard marketing bullshit.
0.8nm. Something TSMC stated they intend to bring to market by 2030.
Yes it is marketing term. But I thought everyone should know that by now.
But past 500 pm, the distance between silicon atoms in the crystal lattice, it will become increasingly harder to ascribe any physical sense to it at all.
Similar how music did not change much in the last 20 years
