The winner in the foundry business used to be determined by who got to the most advanced process node first. For the most part that benchmark no longer works.Unlike in the past, when all of the foundries and IDMs competed using basically the same process, each foundry has gone its own route.

And while performance and power are still critical elements of a design, there are multiple ways to get there.
