I've always wondered how people on HN are able to spit out detailed answers like this with references and facts with such great ease as part of a back-and-forth conversation. Are you a professional in hardware? Or just an enthusiastic follower?

The various node steps are pretty well defined along with the players.

* For CPU design it's AMD, Intel and ARM players (Apple, Samsung etc)

* For discrete GPU it's really AMD and Nvidia, Intel may be moving into discrete but have traditionally only delivered on within an integrated CPU/GPU package.

* For manufacturing it's Intel, Samsung, TSMC, Global Foundaries.

* And major node steppings at the moment are 14nm, 10nm, 7nm, 5nm, 3nm (there are some less "standard" steppings such as 12nm, 8nm etc. but it's worth noting that these are somewhat marketing monikers at this stage anyway).

And so to find references you can pretty much combine these aspects to come up with the various articles.

I personally love nerding out on chip technology, no major expert just find it interesting to follow.
