3200 14 vs. 3600 16 with Ryzen 7 3700x and x570 board

For that cpu and mb would it be better to go with the lower speed and timing, or better to go with the higher speed and timing. I would assume at that around that speed it would be better just to go with the cas14. Is that the right call? https://pcpartpicker.com/list/Cq2Bb8

Doesn't matter with 3000 series.

AMD runs PCIe bus over memory fabric and had to double the fabric bandwidth for gen 4.0.

This removed the bandwidth limitations almost entirely, so all faster RAM does is make the fabric clock slightly faster, but that doesn't have much of an effect anymore since the fabric bandwidth isn't a limitation.

3200 CL14 is probably a sammy b-die kit, so like someone has suggested get 3200 CL16, like a micron e-die kit, instead for almost half the price and spend a few minutes to manually tune that.

Gilroar is right, the newer Ryzen CPU do not see the boost from faster RAM the older series did.

That being said, in general higher memory speed is better then lower latency. In short the 3600 will preform very slightly better.

While I'm pretty sure the 3200 CL14 is slightly faster, 3600 CL16 is much cheaper and easier to come by

It's not in reality. Theoretical perhaps, but not in the real world.

In general the right answer IMO would be 3200CL16 and put the money somewhere else. If you have it to spend, 3600CL16 would be the feel-good choice.

Get the cheaper kit. That would be a good buy. ;)
