Semiconductor Engineering / AI Hardware / Corporate Strategy
COLD OPEN
"When I took over AMD, the company was a month from running out of cash. Everyone said we were done. But the problem was not the engineers — it was the strategy. We needed to stop competing on volume and start competing on coordination: heterogeneous chiplets, interconnects, the architecture of how pieces communicate with each other. The silicon is easy. The coordination layer is what wins."
OVERVIEW

Electrical engineer who became one of the most consequential CEOs in semiconductor history by turning AMD from near-bankruptcy into a $200B+ company. Her insight was architectural: instead of competing chip-for-chip, she pioneered chiplet design — modular silicon tiles that communicate through high-bandwidth interconnects. The MI300X AI accelerator places CPU and GPU chiplets in the same package, creating a physical coordination layer between compute types that dramatically reduces memory bottlenecks in AI workloads.

WHY THIS VOICE MATTERS TO KNOWWARE
Su's chiplet architecture is a physical embodiment of coordination intelligence. Rather than monolithic processors, her chips are networks of specialized tiles coordinated by high-bandwidth interconnects — the silicon equivalent of the three-body pattern. The MI300X's integrated CPU-GPU design means the coordination cost (data movement) is minimized at the hardware layer, making it disproportionately powerful for AI tasks that require tight coordination between memory and compute.
