For marketing purposes, nm is the new Hz. Once, clock speed 'mattered' and was used in marketing to indicate a CPU that did work faster. There was a period of time where Hz was still used by marketing, yet it had stop reflecting how much work the CPU actually performed in a given amount of time. The public caught on that Hz mattered less. Now, they're hoping nm matters in marketing (no as 'this is a faster chip' but 'this chip uses 'better' technology than TheOtherGuys/ThePreviousGeneration/WhatEver) for at least a few moments before the marketing team has to come up with some other differentiator.
