It's been decades since published node sizes had any connection to actual feature size. Sadly this is just how it works in the semiconductor industry now.

- roelmore 4mo agoSmart money would be on the first person who realized that the expertise required to understand the technical details had grown beyond that possessed by 51%+ of stock investing (trading?) population as weighted by transaction volume.

- Legend2440 4mo agoYour article says it started earlier: >So essentially, since 1997, the node name has not been a representation of any actual dimension on the chip, and it has erred in both directions by almost a factor of 2.
- bobby_zhu 4mo agoWe've already been through years of "7nm isn't actually 7nm" across different fabs - completely different measurement conventions, none corresponding to real feature sizes. Now sub-1nm? If it is real then at that scale we're probably in the several atom width territory.
