Intel's 22nm Process. Atom, ARM, Apple

Intel had a big press event yesterday at which they announced details of their 22nm process. In a change from their current processes, it goes with a vertical gate. In fact 3 gates which gives them much better control of leakage through transistors that are switched off, along with more transmission through the on transistors. They claim to get 37% better performance and 50% power reduction compared to 32nm. Although vertical transistors have been talked about for nearly a decade, Intel's tri-gate is the first time anyone has brought them into volume production.
