How much real world performance difference between these two timings.
DDR4-3600Mhz CL 16-19-19-19-39 1.35v
and
DDR4-3600Mhz CL 18-22-22-42 1.35v
 
In some programs it will be more than the performance difference between 3600 vs 3600x or 3700x vs 3800x but in other programs there will be no difference.
 
3600 c16 $83 vs 3600 c18 $78 ~$5 difference for about double the performance gain in games you would see with 3700X vs 3800X which is $30 extra.
 
I can 'see' an FPS difference outside the margin of error from 3200 C16 to 3200 C14 to 3600 C16 when I am benching with graphs/results, but can't feel the difference ingame.

I've currently OCed my RAM to 3600 16 20 20 20 40 timings.
 
3600 cl16 vs 3600 cl18 you won't really notice a difference. I OCed my memory from 3200 CL14-14-14 to 3600 CL16-18-18. To be honest I don't really notice much of a performance boost. But I leave it OCed because I can and, well, YOLO :D
 
3900x Auto CPU settings with 3600 Tuned Mem 1800 Infinity
Only in top Games I see Small difference

Not much of a OC more of a side step and the final RAM latency may actually be worse although you would improve latency a little due to the Ryzen IF.
I have my 4x8GB 3200c14 at 3600 14-15-15 1.45v with 2x8GB it runs 14-14-14 3600 1.45v or 3866c16 1.42v.

It is worth keeping in mind that a few tweaks can add up to a noticeable improvement even if each on there own is not noticeable.
3800X over 3700X ~2%
3800X OC ~5-10%
3600c16 RAM at XMP ~2-5%
OC the RAM to 3733 ~1-3%
Tweak sub timings ~10-15%
Total ~20-35% increase in CPU performance but this will only be noticeable in completely CPU bottlnecked gameplay and there is the odd game like Crysis 3 which really doesnt care so much about RAM speed where the gains will be less.

CAS latency is 8.89ns for 3600CL16 vs 10 ns for 2600CL18. (3200CL14 is 8.75 ns.) You'd have to be running something with pretty horrific memory access patterns to notice a 1+ ns latency increase subjectively.
 
"Feeling" the difference in games is entirely dependant on the game.

On something like Arma 3, where it is difficult to even get solid 60 FPS on ultra with the most power CPUs out there, a few extra FPS is not something to sneeze at. Any game where you are going over 100 FPS it's not gonna matter much. Maybe for the lows.
