The chiplet model marks a departure from the generations of monolithic integration. Not just multiple gate oxides on a SoC, but actually parts from different fabs. The supply dynamics gets interesting. AMD combines TSMC 7nm with GlobalFoundries 14nm. Intel uses its own processes, but combines 10nm with 22nm for Foveros.

AMD says chiplet design can cut costs by more than half
AMD has consistently beaten Intel in cost-per-core, but did AMD really need to pursue a chiplet design to make Zen 2 so affordable? New slides from a recent talk at ISSCC show exactly how much the company saved with this approach, and the results are very impressive.
