You have it the wrong way around. The nm number used to mean minimum gate length. But when moving to FinFET and other transistor innovations that provided increased density, they decreases the “nm” number AS IF the increased transistor density came from shrinking gate length with a traditional planar transistor. The nm has always been a very rough approximate proxy for transistor density. Nothing has really changed about how what the number implies. I find it so weird how so many people on hacker is so hung up on the “nm” numbering. None of these people are designing standard cell libraries and those that actually design standard cell libraries never cared about what’s in the marketing material anyway. Lowe number means higher transistor density in some ways, on some parts of the chip. That’s all
