BTW, I can't buy the TridentZ Neo, so I have to choose between this two:

Leaning toward the G.Skill Trident Z: Samsung B-die, slightly better timings, and it's on your mobo's QVL list.

I'm really lost with this, I don't know what memory buy for the 3700X for gaming. I was between Trident Z Neo 3600 CL16, Trident Z Neo 3200 CL14, but I don't know what is better for this that I want.

3600 CL16 is better in paper, but hoe much do they cost?

I'd start with checking your motherboard's QVL (qualified vendor list), then narrowing your search to DDR4-3600 with the lowest CAS latency that you can afford. IIRC, Ryzen 3000's infinity fabric (FCLK) will scale 1:1 up until 1800MHz (so DDR4-3600) until you start seeing diminishing returns.

From my understanding the performance will be very similar for both on 3700x.   The 3900x with the 2 chiplets benefit more from the faster infinity fabric (FCLK) 1600mhz vs 1800mhz, but a 3700x i don't believe has the same benefit.  Getting memory benchmarks using 3700x to compare what you are asking is hard to find as i was looking for the same.  Most use a 3900x CPU to compare where the FCLK matters more (in my opinion).

 

I would suggest going with whatever is cheaper.

The 3200 is 6€ cheaper the 3600 memories, 179€ and 185€.

 

 

Reading the Spartan VI and Allan B's post, I think that I'd go for the 3200, but, for 6€... xD... Yeah, I think that, the 3200.

3600Mhz then since you're not that price sensitive (if you are, you wont be buying RGB stuff).

that's just AMD's marketing material. 1800MHz FCLK is their "generally obtainable" number, good chips can reach 1900MHz.

 

Also there's no such thing as "1800MHz+ gives diminishing returns", it scales linearly upwards as long as your memory can keep up.

Single chiplet still get all the benefits. Infinity fabric is still responsible to connect each core to the shared L3 cache and the I/O die.

This is what I was referring to when referring to going above DDR4-3600:

 

Judging how performance actually falls off, there must be something wrong with settings their motherboard's running. Not the first time LTT screwed up, for example the "9900k slower than 9700k" accident.

I find it really odd there are so many replies, but no one has asked what Motherboard you will be using, as that will dictate much...

^ 2nd reply was to check the QVL for his motherboard. But I see you're banned anyway.. so ¯\_(ツ)_/¯

Hardware Unboxed came to a very similar conclusion. Basically decoupling the FCLK from 1:1, which IIRC is what you'd need to do above DDR4-3733, adds latency. Sure, you can overclock FCLK to keep the ratio 1:1, but not all IMCs are created equal. Most can do 1800MHz out of the box, but many cant get anywhere near 1900MHz.

Leaning toward the G.Skill Trident Z: Samsung B-die, slightly better timings, and it's on your mobo's QVL list.

That will be then, thank you all!
