Symbol C_fixed

CfixedC_{\text{fixed}}
CfixedC_{\text{fixed}}

What this part means

the amortized hardware and facility cost per unit time.

Its job in the formula

CfC_fixed is a part of this expression. Its role is fixed by the surrounding article and by the operations shown in the formula.

Where the article explains it

Here CfixedC_{\text{fixed}} is the amortized hardware and facility cost per unit time, CenergyC_{\text{energy}} the energy cost per unit time, Tmax⁡T_{\max} the chip’s maximum achievable token throughput under ideal batching, U ∈\in (0,1] the realized utilization fraction, and m a margin term.

The passage around this formula

Here CfixedC_{\text{fixed}} is the amortized hardware and facility cost per unit time, CenergyC_{\text{energy}} the energy cost per unit time, Tmax⁡T_{\max} the chip’s maximum achievable token throughput under ideal batching, U ∈\in (0,1] the realized utilization fraction, and m a margin term. This is not a model any…
