That's CAS latency. To calculate the latency of a timing you divide the timing itself by the clock frequency of your sticks. For example, DDR4-4000 CL14 is running at 2000MHz = 2GHz, so the CAS latency is 14/2 = 7ns.

But it's just a singular timing that's not even used all that often, so it's not that relevant to performance anyway - https://www.youtube.com/watch?v=pgb8N23tsfA
