It is all marketing bullshit at this point. TSMC's 12nm process is a rebranded version of their 16FFC low power flavor, with literally no other changes other than name so that they can market as being smaller than Samsung/Global/Intel's 14nm processes. All of the foundries are just naing the newest node roughly in line with the original ITRS roadmap names, even though the smallest feature sizes on the most advanced node in mass production at the moment (Intel's 14nm, which is a good 20%-30% smaller feature sizes than Samsung's "10nm") is around 42nm (source: http://images.anandtech.com/doci/8367/14nmFeatureSize.png http://images.anandtech.com/doci/8367/14nmFeatureSize.png)
