It never stopped being true, but a lot of what makes a processor faster these days is smarter layout, better branch prediction, and better microcode. Process size matters, but it’s probably less important than it was in the 1990s.

Also, there's a difference between the minimum feature size that can be fabricated (mostly a lithography challenge), the minimum size of a reliable device that works well (e.g. with enough doping atoms in the channel) and the size and shape a specific transistor needs to be for its particular requirements.
