What is a die?
A die is a single chip cut from a finished wafer: one rectangular piece of silicon containing a complete circuit. Larger dies fit fewer times on a wafer and are more likely to contain a defect.
Why it matters for investors
Die size is a key input to manufacturing cost: the more dies a wafer yields, the lower the cost per chip. Very large processors, such as many AI accelerators, approach the maximum area a lithography tool can expose in one step.
This is one reason companies split designs into several smaller dies, or chiplets, connected inside one package.
