Process–architecture–optimization model
Process–architecture–optimization is a development model for central processing units that Intel adopted in 2016. Under this three-phase model, every microprocessor die shrink is followed by a microarchitecture change and then by an optimization. It replaced the two-phase tick–tock model that Intel adopted in 2006. The tick–tock model was no longer economically sustainable, according to Intel, because production of ever smaller dies becomes ever more costly.
