Question 6400 CL32 vs 5400 CL 46 for an i9-14900 ?

[Regev]

One sells for about $250 where I live, the other for $200.

Any real-world difference between the two?

* I see 6000@CL30 mentioned everywhere; is it better just for AMD or for both? Costs the same as the 6400 here.

Thanks

You can compare performance between different ram specs by
dividing frequency with CL number.
So
6400/32 = 6000/30 = 200 ( performance is ~ the same)
5400/46 = 117 ( is way worse)

I did the calculations - ended up being about 5 versus 8 nanoseconds of latency. Really how noticeable is it even in the highest workloads?

CL 46 is really bad. I wouldn't choose that.
But it's up to you to decide, if it's worth saving $50 for significantly inferior ram performance.

I found these options as well:

5200 CL40 - $150
6000 CL34 - $175
6400 CL30 - $190
