According to this video using an electron scanning microscope on amd and Intel chips, the “7nm” or “10nm” number does not measure anything, and is effectively a process version number for marketing. From memory there is no single number for measuring transistors or efficiency, transistor density is useful, but it doesn’t tell you the performance or power usage.

- ajmarcic 6y agoBoth performance and power usage are physically functions of transistor density. Assuming the apples-to-apples comparison of similar transistor counts, operating TDPs, and processor designs.
- MayeulC 6y agoMoore's law always was an economic roadmap. Everything in the semiconductor industry is (was) planned around the transistor density doubling every two years, from hardware investments, to market segmentation, to microarchitecture design, to software optimizations. So I think it makes sense that they go on with pushing transistor density from generation to generation, and convey it to the public using names it is already familiar with. It's right that power has severely limited performance despite increasing the transistor density lately. Maybe we'll once again get better with adiabatic computing?
