What is Thermal Yield?
Thermal Yield is the proportion of total facility power that reaches silicon as useful compute, after cooling, conversion and distribution losses. It captures three loss mechanisms usually accounted separately: the power consumed by cooling, the power lost in conversion and distribution, and the compute lost to thermal throttling.
Definition
Thermal Yield is the proportion of total facility power that reaches silicon as useful compute, after cooling, conversion and distribution losses.
Why it matters
Thermal Yield is the engineering quantity behind the commercial metric. It captures three loss mechanisms that are usually accounted separately: the power consumed by cooling, the power lost in conversion and distribution, and the compute lost to thermal throttling. The third is the one conventional accounting misses entirely.
How Coral improves it
By raising loop supply temperature so that cooling consumes less power, by specifying power conversion efficiency as a thermal parameter rather than an electrical one, and by using predictive thermal control to remove the conservative setpoint margin that causes throttling.
Coral's position
The Coral OnPrem Series operates at infrastructure overhead under 6 percent and a typical PUE of 1.05 to 1.15. Coral's roadmap targets the throttling term, which no PUE figure captures.
