It's also about reuse and fungibility. AMD has used the same IO die across multiple generations of Zen hardware. This cuts the dev and validation costs for using new processes. Fungibility helps reduce the cost of making SKUs. Want more cores? Add more compute dies. Your customers want more big chips then expected? It's easier/faster to adapt production since only the final steps differ. The component pieces are the same.
