8 chiplets cut the logic silicon a working chip needs by 50%

A reticle-size chip at 0.1 per cm², Murphy’s model, with 10% extra area on each chiplet for the links between them. Wafer prices are Epoch AI’s modelled estimates, not prices a foundry has published. Defect density, edge and scribe are assumptions, each shown where it is used.

  1. One die $607 858 mm² · 45% yield
  2. 2 chiplets $455 2 × 472 mm² · 64% yield
  3. 4 chiplets $345 4 × 236 mm² · 79% yield
  4. 8 chiplets $304 8 × 118 mm² · 89% yield
