So I've done some investigation on RAM speeds and RAM latency, and I've realized they in cooperation affect the real world latency in nanoseconds.
I've also done some investigation on Newegg to find the various best speeds in addition to latency cycles and compared the real world latency in nanoseconds.
For instance, my Corsair Vengeance memory with 2133 MHz and CL13 gives a real world latency of 6 nanoseconds.
Comparing with a Corsair Vengeance LED memory with 3466 MHz and CL16, it would give a real world latency 4.6 nanoseconds.
So there is a difference by 1.4 nanoseconds. [OBS! Considering I've done all the math correctly]
But how much performance difference would I notice in different tasks with a computer if I would in theory upgrade to the latter memory?
Tasks such as CPU heavy games, RAM heavy games, medium heavy games for CPU/RAM, video editing software, video rendering, audio rendering, audio software/DAW, photo editing, etc.
Does it really matter how much latency the RAM has? By googling you find lots of discussions and tests on wether it has an effect, but it feels like the tests are poorly done, only focusing on either speed or CAS latency, and not comparing different real world latencies in nanoseconds.
So there's not much to go on there.
