The 6-Inch Wafer That Every AI Data Center Depends On

NVIDIA just put $2 billion into a chip factory that runs six-inch wafers — not the twelve-inch wafers the rest of the industry moved to decades ago. The reason is that the chips moving data between processors inside an AI data center aren't silicon at all: they're indium phosphide, and the lasers built on it…

Inside a giant AI system, just moving the data between chips can burn more power than the computing itself — so NVIDIA is doing something wild: replacing the copper wires with light. In this video I break down co-packaged optics (the "light engine" built right into the chip package), why copper hit a hard power…
