[SOLVED] Bottle neck

[Misty947]

Hey guys,

I have a i9-9900ks coupled with 2080ti waterforce, I wanted to upgrade to 3090 or 3080ti.
Used some bottleneck calculators and found that there will be GPU bound bottleneck on avg. of 8%

Any help or advice would be appreciated.

what the question?
and don't waste your time on those calculator. it is depend on what game/resolution

 

[sizzling]

What resolution and Hz is your monitor?

I agree with above, don’t use these calculators.

 

[Misty947]

I use 165hz 1440p monitor, no intention to upgrade it anytime soon.

I use 165hz 1440p monitor, no intention to upgrade it anytime soon.

From a quick look online the 9900k was similar gaming performance to the 3700X. I had a 3700X paired with a 3080 and ran 1440p 144Hz then upgraded to 1440p 240Hz. It was a very good combination, I could max out most games (Ray Tracing off) and get 140+ fps. I was aware several games didn’t use 100% of the gpu as my max fps was cpu limited but it wasn’t a problem as I was getting enough fps for my monitor.

When I upgraded to my 240Hz monitor I later upgraded to a 5800X3D. This was needed to get fps closer or above 200. Now I could not max game settings but tuning game settings and the cpu upgrade gave a good boost of fps.

I’d say a 3080Ti/3090 might be over the top for many games running 1440p 165Hz if not using Ray Tracing but that’s no problem, a little headroom for future games. Your 9900ks might prevent you from reaching 165fps in some games but that would happen regardless of gpu choice. If the cpu can only deliver 140fps to the gpu then that is all you will get.

I don’t see a problem with your setup as long as you manage expectations. You won’t always be able to 100% utilise the gpu and you may not always get 165fps, but you can still get a very good gaming experience.

This is, I do like RT options, and also if a game like CP2077 can bring my PC to the knees, won't future installments of similar caliber games do the same?
I know CP2077 is badly optimized, and yet I feel crushed by the 40fps I am getting.

You have a misunderstanding of the term "bottleneck".

1. The bottlenck calculators are pure junk science. Meaningless.
2. Putting in a better part (here, the GPU) cannot result in worse performance than you had before.

That is obvious, but you can get 5% more performance with this intention, and 5% for 750$ is not a great trade off.

I have no idea what you mean by this.

"5% more performance"?

I will elaborate.
If I upgrade my GPU to lets say 3080ti, and I will have a bottleneck per se, I will gain neglectable amounts of performance.

Incorrect.

The CPU gives the framerate, the GPU provides the eyecandy to those frames.

Lets say you have the i9-9900ks coupled with 2080ti .

(random numbers to follow)
With this combination you see 90fps at medium settings.

You swap in a better GPU, the 3080ti.

You still get the same FPS, but you can turn the graph settings up to high (or whatever)
