Question RAM true latency and frequency

[aidan-astwood]

Would a kit of RAM with equal true latency to another but higher frequency be better performing?

For example: 2666MHz CL18 (13.5 ns) vs 1333MHz CL9 (13.5 ms).

Their latency is the same but the 2666 has double the bandwidth.

In most cases a higher frequency will always perform better. That ratio alone is not the determining factor for performance, it is only a general rule of thumb for comparing performance levels of the same type of memory.
