Latency - The time required to perform an action or to produce a result.
It is measured in units of time - Hours, minutes, seconds, nanoseconds and clocks.
Throughput - The number of actions performed or results produced in a unit of time.
It is referred as Bandwidth in RAM memory. The actions / results per unit of time.
Example: Boeing manufacturing 777 Airbus.
Boeing Factory manufactures an Aircraft in 83 days. The Factory manufactures 730 Aircrafts in 365 days.
Latency is 83 days. Throughput is 2 aircrafts / day or 60 aircrafts / month
Latency and throughput in RAM
Eg: DDR3 PC3-12800 CL 7
12800 MB/Sec - Maximum theoretical transfer rate. CAS Latency 7 tells us it will take 7 clock cycles delay to return a requested data.
There are other common latencies 6,8,9,11
The lesser the latency, the faster the RAM performs.
So, the next time you are searching for a faster RAM, you might want to check for a less latency compatible RAM.
