The H100 die is exceptionally large (814 mm^2 — near the reticle limit of 858 mm^2). Large dies have lower yield, meaning more wafer area gets wasted per good die. This is THE chip training most of the current generation of frontier AI models. The full H100 product also includes 6 HBM3 stacks and a silicon interposer — their footprint is not included here (this app focuses on the logic die only).
