Different process nodes are not directly comparable across companies. Transistor density is still increasing. https://en.wikipedia.org/wiki/Transistor_count https://en.wikipedia.org/wiki/Transistor_count Smaller marketing numbers generally do relate to improved performance, usually from minor optimizations across the board like needing to move less charge to switch a transistor, etc. Also certain numbers introduce things like FinFET or gate-all-around that further increase performance. We are now past the point where just simple size shrink will yield significant benefit, due to physical limits no less. Most of the heavy lifting in terms of performance improvement comes from microarchitecture advancements
