What you're describing is latency, not throughput. They're two different measurements of "speed".

The thing about memory is that latency kills your processing throughput. If the CPU needs the data and it isn't available then the thread stalls until it becomes available. There's various techniques which can sometimes hide this problem, which is what this section of course is largely about.
In the context of making memory which does require cache (the topic of the post), the speed that matters is necessarily latency.
