Intel Tick-Tock

"Tick-Tock" is a model adopted by chip manufacturer Intel Corporation from 2007 to follow every microarchitectural change with a die shrink of the process technology. Every "tick" represents a shrinking of the process technology of the previous microarchitecture (sometimes introducing new instructions, as with Broadwell, released in late 2014) and every "tock" designates a new microarchitecture.[1] Every year to 18 months, there is expected to be one tick or tock.[2] Starting 2014 Intel realized "Refresh" cycles after a tock in form of a smaller update to the microarchitecture. It's said this is done because of the expanding times to the next tick.
