\eta

What this part means

the achieved energy efficiency of the best available accelerator at time t , measured in tera-operations per second per watt.

Its job in the formula

eta 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

If $P_{\text{budget}}$ is the (roughly fixed, application-set) power envelope in watts and $\eta(t)$ is the achieved energy efficiency of the best available accelerator at time t , measured in tera-operations per second per watt, then the usable on-device compute throughput is approximately

The passage around this formula

That structural fact can be written compactly. If $P_{\text{budget}}$ is the (roughly fixed, application-set) power envelope in watts and $\eta(t)$ is the achieved energy efficiency of the best available accelerator at time t , measured in tera-operations per second per watt, then the usable on-device compute throughput is approximately
