Will a ryzen 7 cpu bottleneck a 1080ti?

[jstores]

I'm looking into the r7 series, but I want to know if any of them would be a bottleneck with a 1080ti? (factory OCed), They exact model is the PNY XLR8 accelerate 1080ti.
But, with this gpu how would r7 cpus fare, stock? Could an 1800x unleash its potential and use it while gaming? How about the others (stock)? I've also seen reports that all the r7 processors perform very similarly when overclocked. So would an overclocked r7 cpu paired with the 1080ti not bottleneck?
I haven't built my pc yet, but I have ordered the 1080ti, and I am in the process of building it, per say. I've also read RAM is also an important factor as well, should I get fast RAM, and/or ram for amd cpus? Thanks!

The more you pay for a ryzen chip, the better bin you get.
It seems that the best top out at 3.9 or 4.0.
Normally, that is sufficient for gaming.
But, many games respond to higher performing single cores like the I7-7700K more than they do to many threads which is what you get with ryzen.
Here is a interesting comparison of a 8 thread I7-7700K vs. a 12 thread I7-7800X

spoiler... I7-7700K wins in virtually all games tested using a GTX1080ti.

Bottlenecking isn't so simple like that. It depends on the game in choice, resolution, graphical settings. Because in reality, any CPU can bottleneck any GPU under the right circumstance. In fact, 'bottlenecking' should just be ignored while choosing parts. Instead, worry if the CPU can perform up to your FPS goals and your GPU can perform up to your intended visual quality.

Generally the Ryzen 7 CPUs have the potential to perform fine at AAA games for < 75hz goal, no matter the GPU or resoltion.

Would you recommend the 7800x over r7? I was contemplating between the two. I also forgot to mention that I will be multitasking to somewhat of an extent, and I wouldn't want to have a cpu in which most of it is used up in one program. That is why I am interested in the ryzen cpus along with the 7800x.

If I did some overclocking, do you think I could reach around the 100FPS count stably?

Depends on the game and if the GPU can handle it.

First of all, if you are heavily multitasking, buy sufficient ram to easily hold the contents of all the active tasks.
Do not be alarmed if you see task manager list some 100+ tasks.
They are service tasks of small size and not active.
Usually 16gb is sufficient, but if you are worried, go ahead and buy 32gb. It is a relatively small cost with a budget like yours.

As to how many threads, that will be determined by the apps you run in the background.
There is a good case for ryzen 1800X with 16 threads if you can really use them all.
Most games will only use 2-3 threads, so it is your other work that will determine what you need.
Look at the tests I linked above. For all of the games, the I7-7700K whether or not overclocked and using 8 threads
consistently did as well or better than the 7800X and 12 threads.
The title is a bit misleading, it should have said 8 vs 12 threads.
Then, also, the motherboard needed for a I7-7800K will be more expensive than the Z270 motherboard used for the 7700K.

As to the FPS you might get, it depends on the games you play, the resolution and eye candy you use, and the power of your graphics card.
In the tests above, a I7-7700K consistently reached 100 FPS using 1080P at ultra quality.

the 7800x was in consideration due to the extra two cores for multi tasking and its relatively good performance. It does get beat as you mentioned, by the 7700k in gaming, but too much of a difference. This cpu performs better than the ryzen but paired with a motherboard, it is more expensive. Would you take the r7 or the 7800x?

I will try to respond to the original question as well as I can (as a Ryzen 7 1700 owner):

-In terms of Bottle necking, you will always get some of it (there is no way to perfectly balance a cpu and a gpu. you could do that for one game, not for all).
You have to remember that you can hit many different problems in different games:
A) Your CPU uses only a few threads, so a faster ipc and higher clocks are better.
B) Your GPU does not have enough VRAM, so you will have lower FPS than with another GPU.
C) Your Driver for the GPU is not well optimized, so you will get lower FPS than someone with another GPU.

And this list goes on.

When asking the question if a CPU will bottleneck a GPU, the first question Id like to ask is: How fast is your monitor (refresh rate).
I personally still use a 60Hz refresh rate monitor so anything past 60 FPS is mostly useless for me.

If you use a 144Hz monitor, anything past 144 FPS is useless for you. etc.

In terms of the ryzens performing similar when overclocked its true as far as I know.

I have a 1700 OCed to 3.7 GhZ and I am getting higher scored and frame rates than an overclocked 1800X. This is however a bit of a lottery, not all CPUs perform as well, and I might have gotten lucky.

If you are interested in a 7800X, I would suggest waiting maybe 2 more months to see more data about it once there is not only more information online but also to see if any bios updates might get some improvements.


In terms of Ryzen, I have some bad news thou: The ram modules are very important. I bought some expensive ddr4 modules 32GB G Skill TridenZ 14-14-14-34 to make sure I get Samsung B die (dual rank memory) and I was able to Overclock the ram to 2667 MHz with no problem after the last bios update for my motherboard (gigabyte X370 Gaming 5), and between the CPU overclock and the Ram overclock I was able to get an additional 33% FPS increase in games and benchmarks.

That being said, I was sort of not even worried about that since what I wanted to be sure I would get is good performance when streaming games.
So for me, the 1700 ryzen made a lot more sense than a 7700K at the time I bought it and from what I can tell, its also better than the 7820X, but the problem here is that I can only say taht from 3rd party users as I dont ahve a 7820X:

https://www.youtube.com/watch?v=0ypELk3jl48

Here you can see a small sample of how a 1800X performs in some games vs a 7700k and a 7820X. As I said, a 1700 jsut overclocekd to 3.7 GhZ seems to be even better than a 1800X (this should be possible for ANY 1700 because of how the binning is done, meaning any core of a 1700 has to be able to do 3.7Ghz as that is its turbo boost, you only need enough power and cooling to make it work).

Also, please note that, regardless of my personal experience, there are people whoa re having trouble with Ryzen CPUs, and there are people who are having rather scary temperatures from a 7700K, so you will always have a small risk no matter your choice.

Finally, let me make myself clear, I am using watercoling. While 3.7 GHz is possible on air, it DOES require a good CPU cooler (and even then, its going to run a bit warm, so if you live in a place like say... Spain, where ambient temps can hit to 47C in summer, expect some problems with temps).






I hope this is not too much crazy random info to take into account but this will always be the case with new tech that is in its infant stage. I had my own share of problems with this setup running windows 7, but I quite simply refused to play the "Intel premium" when I could get so much value out of AMD.

What you will do, and its consequence, is up to you.
