Based on tick-tock,

the process comes first and then a new architecture that is built on that process.
Penryn is just a die shrink of Conroe with a few enhancements. It was originally designed for 65nm. Nehalem is designed from the ground-up to be built on the 45nm process technology.

Even if they've enhanced it there's supposed to be gains from designing it ground up for the already tried and true process technology.
