Ok, I am sure there is some questions relating to this but I cannot find a direct answer to what I am finding. I am looking at buying ram, probably 16 Ghz, just waiting on a sale for under $70 and such over time.
To get to the main point, what would be better, ram with all specs the same except for the frequency in mhz and latency, 1600 Mhz with CAS latency of 9 or 2133 Mhz with CAS latency of 11,
Also if latency is better overall than mhz, would it be worth the little extra money to get CAS 7 types?
To narrow down the possible solutions, I am just gonna build a decent gaming type computer, I may or may not game on it but I want it to last for the next 6 - 7 years and still be a decent build. I wont game much but I may try some out from time to time, I do plan on trying out the witcher 3 but not sure if its good on pc or better with PS4. I am gonna get a SSD drive too for speed and a decent video card with 4 GB ram in it, as well as i7 4790k processor when I do build it. But I will wait until theres sales on them to save some money.
Ok I have found an equation via wikipedia that I think will answer not only mine but a lot of peoples questions based on latency and frequency.
The formula is:
(CAS / Frequency (in Mhz) x 1000 = X (in Nanoseconds)
So to compare the 2,
(9 / 1600) x 1000 = 5.625 ns
(11 / 2133) x 1000 = 5.157 ns
So in comparison, the 2133 Mhz would be faster. But by only about half a nanosecond.
If im wrong please correct me but this is what I think would be better.
