Inverted bottleneck?

[Clipper]

I think we have always talked about bottleneck when we put a superior component to an inferior one, but as a rule it has always been a superior GPU to an M.B with a superior CPU.
But... The other way around?
I explain that both my CPU and my M.B and RAM is much superior to my GPU.
I discovered that my GPU (while playing, even though I lowered parameters) is always at 100%.
Is it a silly thing of mine or does it make sense?
Before with a team in the opposite way, worse CPU RAM and motherboard I didn't have this problem.

@clipper Yes, it makes perfect sense.

Indeed, when the GPU is at 100% and the rest of the components are at low/medium gas, you are experiencing a bottleneck where the graphics card is not keeping up with the rest of the components, resulting in an imbalance in the results (games, applications, etc.).

As I mentioned to you in the other thread, do the calculation in the Bottleneck Calculator, marking GPU-intensive tasks, and you will see that your system is around 40% bottlenecked in the GPU compared to the CPU.

@Sylver vamos...que te vendó mi rtx and I got another

[_Neptunno_]

@clipper before you didn't get the most out of your GPU and now you don't get the most out of the CPU
In the end you have to do business with @Sylver!!

Well, maybe you should look at an RX 6700XT or similar to get the most out of the CPU, although for now you can try to hold out to see if you find a good deal now that the price is dropping (slowly) of the graphics cards.

@clipper It's not that I want to force it in fact I thought the team was going to be much more balanced... But it seems that the new platform you've picked up is much more powerful than I thought in proportion to the performance of the RX 580...

In any case, I am still looking for an RX 580 of 8Gb, in case you decide to replace it at some point

But as @_Neptunno_ rightly says, try to hold or even relax CPU frequencies (if possible with your card), in order to bring one closer to the other and stabilize the performance until you see the opportunity to change.

I would have sworn that my GPUs have always gone to 100% in games, all my life now you make me doubt.

[Clipper]

@krampak I think that no component always renders at 100% except in stress tests.
Maybe with the game Crysis...
But in the rest I have never had the graphics at 100% constantly.

@clipper well I just started looking at it in World of Warcraft (a game that has always been more CPU-intensive than GPU) and there it is, pegged at 100% xD while the CPU curiously has more margin:

[Sylver]

@krampak Looks like a clear example of the GPU bottleneck that Clipper was talking about.

Your CPU is eating a potato with the RX 580... No, you'll all get rid of the RX 580s now that I finally found one... Life is a joke

Saludos!

[krampak]

@sylver well I don't know, I have my doubts that it is that.

[Clipper]

Maybe the comparison should be with the same game.
I think the one that we all possibly have is battlefield 3.

P.d and it gives me a lot of trouble to look for the origin account.

@sylver said in Inverted bottleneck?:

@krampak It seems a clear example of the GPU bottleneck that Clipper was talking about.

Best regards!

But the RX 580/590 (Polaris) was top of the range, before Vega appeared, in 2017. Krampak's i3 is from 2017, although it's true that it was practically like an i7 since it was 4/8.
So, being low-end in theory, the CPU should cause "something" of a bottleneck, but with some OC it will have a bit more performance and it's not a bad processor, despite being just an "i3" hehe. We must also look at the resolution at which you play, the graphics options enabled, programs running in the background and the optimization of the games.
Honestly, I don't think you have to worry about the GPU and CPU running at 100% to be concerned about the bottleneck issue, I would understand it as problematic (the PC is unbalanced) to see the GPU at 100% and the CPU below 30-40%. But of course that's in all games, not just a specific game because the optimization can play tricks on you and make you think what isn't.
Returning to Clipper's topic, I'm sure that if a test of the game was done with both teams at 720P, you would notice a lot of improvement in the Ryzen and how it gets the most out of the RX580. Certainly the CPU has some bottleneck, but it's sure to be good enough to play more than we think, only that for this game that Clipper is most interested in, the improvement isn't as noticeable.
By the way, good monitor, although to get the most out of the 165hz, you need a more powerful GPU and possibly you wouldn't go below an RTX 3080 to ensure good performance for a long time, we're talking about at least a 3070ti.

Best regards!

[Clipper]

@_neptunno_ so we'll have to wait until Friday "silly" to get the GPU, even though after seeing my "work schedule" I might be able to set up a tri SLI, just with the hours

[Sylver]

@krampak Well you're right, the 8350K is theoretically even a bit weak for the RX580, I hadn't done the calculation... Unless the micro's OC makes it far surpass the graphics, something must not be going well...

[_Neptunno_]

@sylver but that it is at 57% CPU usage should not mean that the performance is bad, just that the processor does not need to use all its potential. I have read on the Steam forum people complaining about having the CPU at 100% and having stutters in the game because of other applications running in the background. What I don't understand in this case is the use that WOW will make of it, no matter how CPU demanding it is, if the 8350k is up to the task, it should not be necessary to be at 100%.
Surely with the classic Tomb Raiders the CPU is at 2% and the graphics the same hahaha

Greetings!!

[Sylver]

@_neptunno_ Yes, I guess it will be a matter of trying it out in more games to see how the CPU and GPU behave under other conditions.

Man of course, with the old Tomb Raiders, the components don't even wake up hahaha

Greetings!

Out of boredom today I tried it. The ARK with high settings, everything on high and something on "epic"
78 stable FPS and the GPU at 100% CPU RAM and other things at most at 15%
So the issue of the bottleneck... seems like not.

Hello.

No, that percentage is not a direct indicator of, let's say, how much gpu you have left.

I have read that it is not so, and I have also observed it for myself. Apparently, only if the graphics card starts doing something "worthy of its capabilities" will it approach or hit that 100%, but that is not net performance, it still has a lot of juice left.
The gpu's performance ceiling is reached when the framerate starts to drop, or rather, it is being reached. When the framerate is not satisfactory with the graphics quality you want to have then your graphics card has hit the ceiling.

As for the "bottleneck", whoever reads this is going to think that the graphics card is getting less performance because of working with a bigger micro Jjj, if you came across an opportunity for a top-notch graphics card, and then you weren't enjoying it because you couldn't upgrade the micro, that would be a big hassle.

Come on, without beating around the bush, we all love updating hardware

By the way, what graphics options are you thinking about when the time comes?

[Clipper]

@defaultuser
Well, in my case, if the economy allows it at the time...
To double...
I mean, if I have one with 8 GB
Look for something with 10 or 16 GB of VRAM
And a preference for AMD.

I think like krampak, if the game uses all the cores of the GPU, then it will be full loaded, as the CPU would be if the game used the CPU basically, as in the case of chess programs, but reading this, you make me doubt too (I have to try an engine that uses CUDA, to see if I can put a graph of the use of the Nvidia RTX3060).
