Tick–tock model
Production model by Intel
Tick–tock was a production model adopted in 2007 by chip manufacturer Intel . Under this model, every microarchitecture change (tock) was followed by a die shrink of the process technology (tick). It was replaced by the process–architecture–optimization model , which was announced in 2016 and is like a tick–tock cycle followed by an optimization phase. As a general engineering model, tick–tock is a model that refreshes one side of a binary system each release cycle.
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.[ 1] These occurred roughly every year to 18 months.[ 2] In 2014, Intel created a "tock refresh " of a tock in the form of a smaller update to the microarchitecture[ 3] 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 are produced under a single manufacturing process, with the third generation out of three focusing on optimization.[ 4] The first optimization of the Skylake architecture was Kaby Lake . Intel then announced a second optimization, Coffee Lake ,[ 5] making a total of four generations at 14 nm.[ 6]

Atom roadmap
With Silvermont Intel tried to start Tick-Tock in Atom architecture but problems with the 10 nm process did not allow to do this. In the table below instead of Tick-Tock steps Process-Architecture-Optimization are used. There is no official confirmation that Intel uses Process-Architecture-Optimization for Atom but it allows us to understand what changes happened in each generation.
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;[ 13] 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.[ 71] In 2018, Intel announced that Knights Landing and all further Xeon Phi CPU models were discontinued.[ 72] However, Intel's Sierra Forest and subsequent Atom-based Xeon CPUs are likely a spiritual successor to Xeon Phi.
