Chiplets: Why Processors Are Being Built in Pieces

One processor can contain several separate pieces of silicon. Chiplets let designers divide functions, reuse compute designs and choose suitable manufacturing processes. But the package must connect, test, power and cool those pieces as one dependable product.

This video follows the trade from Gordon Moore's 1965 board-level modularity discussion through AMD's chiplet milestones and modern packaging. It explains die yield, reticle limits, compute versus I/O, memory requests, bandwidth, latency, cache coherency, interposers, Intel EMIB and vertical stacking.

Then it examines known-good-die screening, assembly losses, heat paths and shared power budgets. UCIe provides common package-level connection rules, but link compatibility still leaves firmware, qualification, supply commitments and responsibility for integration.

Research checked 12 October 2026. The latest update includes GlobalFoundries' 8 October interposer agreement with TSMC, with a future production target, and AMD's Versal RF roadmap. Shipped products, demonstrations and future targets remain distinct. Vendor claims are attributed; no universal cost saving or performance percentage is promised.
