Tick-tock model

Tick-tock is a model adopted in 2007 by chip manufacturer Intel. Under this model, every microarchitecture change is followed with a die shrink of the process technology.

History

Every "tick" represented a shrinking of the process technology of the previous microarchitecture (sometimes introducing new instructions, as with Broadwell, released in late 2014) and every "tock" designated a new microarchitecture. Every year to 18 months, there is expected to be one tick or tock.

In 2014, Intel created a "tock refresh" of a tock in the form of a smaller update to the microarchitecture not considered a new generation in and of itself. In March 2016, Intel announced in a Form 10-K report that it deprecated the tick-tock cycle in favor of a three-step "process-architecture-optimization" model, under which three generations of processors will be produced with a single manufacturing process, with the third generation out of three focusing on optimization. The first optimization of the Skylake architecture was Kaby Lake. Intel then announced a second optimization, Coffee Lake, making a total of four generations at 14 nm.

Intel believes that it will be possible to reach at least 7 nm, perhaps using indium gallium arsenide (InGaAs) or graphene rather than silicon.

Roadmap

Note: There is further the Xeon Phi. It has up to now undergone four development steps with a current top model that got the code name Knights Landing (shortcut: KNL; the predecessor code names all had the leading term Knights in their name) that is derived from the Silvermont architecture as used for the Intel Atom series but realized in a shrunk 14 nm (FinFET) technology.
