Typically, CI builds above a certain size include parallel sections to utilize multiple agents. With parallel pipelines you can measure the wall-clock time it takes for a set of changes to go from having been pushed to version control to being built, verified and deployed. The build cache's effect in this case can be measured in the reduction of the time developers have to wait for feedback from CI.
