    Aren’t these sizes a marketing gimmick anyway? They used to mean the gate size of a transistor, but I don’t think that’s been the case for a few years now.

      They’re generally consistent within a single manufacturer’s product lines; however, you absolutely cannot compare them between manufacturers because the definitions are completely different.

      No, it still means what it always has, and each step still introduces good gains.

      It’s just that each step is getting smaller and MUCH more difficult and we still aren’t entirely sure what to do after we get to 1. In the past we were able to go from 65nm in 2006 to 45 in 2008. We had 7nm in 2020, but in that same 2 year time frame we are only able to get to 5nm

      And now we’ve reached the need for decimal steps with this 1.6.

        Later each new generation process became known as a technology node[17] or process node,[18][19] designated by the process’ minimum feature size in nanometers (or historically micrometers) of the process’s transistor gate length, such as the “90 nm process”. However, this has not been the case since 1994,[20] and the number of nanometers used to name process nodes (see the International Technology Roadmap for Semiconductors) has become more of a marketing term that has no standardized relation with functional feature sizes or with transistor density (number of transistors per unit area).[21]

        personally, I don’t care they try to simplify these extremely complicated chip layouts, but keep calling it X nanometers when there’s nothing of that feature size is just plain misleading.
