Docentship lecture - Yuan Yao: "Why Chips Broke Apart - Scaling Limits and the Rise of Chiplet Architectures"

Warmly welcome to a docentship lecture presented by Yuan Yao. The lecture will be held in English.

• Chairperson: Professor Mohamed Faouzi Atig
• Representative of the Docentship Committee: Professor Natasa Sladoje

Short summary: For decades, processor performance gains were driven by increasing single-die complexity, guided by Moore's Law and Pollack's Rule. This lecture revisits how these scaling principles led to diminishing power efficiency and manufaturing yield, and how they motivate chiplet-based architectures as a response to these challenges.

Throughout the lecture, we will learn different architectural and packaging design-choices, and their influence on latency, power budget, and system-level scalability of cutting-edge processors. We will also examine a real chiplet-based processor chip from AMD as a first-hand case study.

Keywords: Computer architecture, Chiplet-based design
