It's not just host nations of the Olympics that are decided almost decades in advance, but also Intel's silicon names and the fab process they're going to be built on. Intel has its plan for the greater part of this decade already charted out, well beyond the upcoming Ivy Bridge architecture. Intel follows the "tick-tock" product cycle, where every micro-architecture gets to be built on two succeeding fab processes, and every fab process getting to have two succeeding micro-architectures built on it, in succession. Westmere is an optical shrink of the Nehalem architecture, it was a "tick" for the 32 nm process, Sandy Bridge is its "tock", and a new architecture. Ivy Bridge is essentially an optical shrink of Sandy Bridge, it is the "tick" for 22 nm process.
Ivy Bridge will make its entry through the LGA1155 platform in 2012, it will make up the 2012 Core processor family. Haswell is the next-generation architecture that succeeds Sandy Bridge and IvyBridge, it will be built on the 22 nm process, and is expected to arrive in 2013. Roswell is its optical shrink to 14 nm, slated for 2014. Looking deep into the decade, there's Skylake architecture, that will span across 14 nm and 10 nm processes with Skymont. This model ensures that Intel has to upgrade its fabs every 2 or so years, an entirely new micro-architecture every 2 or so years as well, while providing optical shrinks every alternating year. Optical shrinks introduce new features, increased caches, and allow higher clock speeds. 10 nm for processors by 2018 sounds realistic looking at the advancement of NAND flash technologies that are pushing the boundaries of fab process development. NAND flash is much less complex than processor development, and hence serve as good precursors to a new process.
