Comparing CL16 and CL18 models at 3600MHZ RAM offers different performance characteristics.
so i am doing a new pc build and am trying to decide to go with cl16 or cl18 is there much difference in speed and latency or peformance
I think you're looking for cl18 since RGB isn't the goal. Cl16 is a better choice and you could likely overclock it to cl14, possibly reaching 3733 or even 4000mhz with a bit more voltage. Cl18 might need extra voltage to reach cl14, and once you hit cl14, further RAM frequency increases won't be possible. Some people have managed 3200mhz at 4000mhz, but I'm not sure about cl18 at cl14. It really depends on the specific RAM chips you're using. It would help to share links to the RAM you plan to buy.
It depends on the cost. If the price is low, grab it; otherwise, skip it. You could notice about a 10% variation in performance, but it’s not worth the $20 extra. Better save it for another purchase.
Usually it won't apply to 99% of cases, unless latency issues arise.
If you're unsure about the distinction between CL18 and higher-end CL16, it's likely you don't need the more expensive option. The performance gain is minimal at best. You'd probably only notice it during operations with strict latency limits. If you're focused on specifications, investing in CL14 3600 MHz RAM is a solid choice and offers no further benefit.
3600MHz CL18 offers a total latency of 10ns, compared to CL16’s 8.9ns. That gap isn’t huge, but for memory-intensive tasks, the extra 1ns can quickly become noticeable. Unless you’re budget-conscious, it’s better to choose CL16—it’s worth it without sacrificing speed.
