I was looking at the Wikipedia page for CAS Latency: https://en.wikipedia.org/wiki/CAS_latency
And I noticed the obvious trend - at higher frequency, despite CAS latency degrading (growing), the delay to get the 1st, 4th and 8th word overall improved regardless.
I've heard in the past that frequency/CAS was perhaps the best metric for memory performance as a consumer, but this chart seems to disagree:
So my main question(s) are:
- Is getting the 1st, 4th and 8th word an accurate representation of real-world performance of memory? If not, why not, and what would be?
- If there some other factor to memory performance that would be a third "hidden variable" that I'm not accounting for, that's not constant between all these? The IMC's performance at high frequency? The motherboard's? Signal noise?
Thanks for any thoughts!
