Ryzen 5600x memory

In terms of performance, which would be better?

- 3600Mhz with CL18

- 3200Mhz with CL16

 

Knowing very well that 4000Mhz would be the sweet spot, but is bit too expensive.

Neither.

You want 3600mhz CL16, not CL 18 if you can.

AMD has already said that 3800 is the new "sweet spot" for Ryzen 5000, not 4000.

Unless I'm mistaken and this has been disproven, it states that 3800Mhz is optimal for the 3000 series

3800 is the strap above 3600, the first strap where it automatically divides the fabric clock.

 

AMD is saying that 4000 is now the firat strap that automatically divides fabric, making 3800 the sweet spot, just before that.

With 3000 series a few could do 1900 IF, a lot could do 1867 IF, all could do 1800 IF (possible there are lottery duds that can't even do that, idk)
So according to AMD some of the 5000 series will do 2000 IF, many will do 1967 IF and all should do at least 1900 IF  This would mean absolute best performance at 4000 mhz ram, 3800mhz is the minimum expectation one should have.

I'd like to thank you both for the clarification. 

Currently looking at this 4000Mhz kit but I'm kinda worried about the CL19 latency.

3200 CL16

3600 CL18

4000 CL19

3200&3600 are equivalent timings, 4000 cl19 is better (10ns vs 9.5ns using basic memory calculations)

Yes I know, but if the big picture is true and if 4000 is the sweet spot for the new ryzen, I probably can only reach it with 3600mhz stick right? Or can I overclock 3200 to 4000 with stable system?

It's pretty easy to OC 3200MHz kit to 3600MHz. To 4000MHz, may be need some luck. Also, I doubt how big the gain in performance from 3600MHz to 4000MHz for Zen 3. With have to wait for reviews.

I have a 3000mhz cl15 crucial ballistix micron e die kit running 3733, experimenting with timings over the next little while...
Even with the 4000mhz kit it relies on other factors, but the 4000 kit has been binned more/better
