Does Bottlenecking matter?

[greenhunt2003]

Guys, I used this bottleneck calculator: http://pc-builds.com/calculator/

 

I have tested my Ryzen 5 3400G with a GTX 1050 Ti and it produces around 30% of the bottleneck.

 

Ok, I don't even care about "bottlenecking". You wanna know why?

No. 1 - Just because bottlenecking means that the CPU limits the performance of the GPU, doesn't mean that they don't work together at all. The CPU handles and deals with the instructions, while the GPU renders video.

No. 2 - The powerful GPU can still run well with a weak CPU, but less than full expectations of performance.

No. 3 - The word "bottleneck" is just Cassandra.

 

Bottlenecking is almost like comparing the size of an elephant to a mouse. It is when one or more components limit the performance of a particular component.

 

Goddamn dude, I have rights to put whatever components I want. I can even install an RTX 2080 Ti to a Celeron, Pentium or i3 machine.

and that's your mistake... these calculators base their info on a single scenario or even just out of thin air

yes, but will be held back if one is slower with something, as the other will have to wait around, which is technically speaking the "bottleneck", but those will always occur, depend on workload and everything.

yes, but I'd probably call you stupid if you were to actually create a bottleneck this big

I'm just joking man.

which is why that you won't get maximum performance from a GPU because a weak CPU is the limiting factor.

tbh, I wouldn't recommend this to anyone because it will just spread fear and stress.

On average, depending on what you do. Something this website only has a little disclaimer for.

1. yeah, so if something is a bottleneck depends on what you do

2. of course, but what you said is a bottleneck. Something not running as fast as it could, because another component is holding it back. So I don't see this as an argument on why one should not care about bottlenecking.

3. I fail to see how 'a Cassandra' is relevant here. You said yourself with bottlenecking not necessarily something bad would happen.

This sounds a lot like a 'I can do whatever the heck I want as a sovereign citizen of planet Earth!'-kind of thing.

Sure you can do that, for a lot of purposes, a more balanced setup makes more sense.

 

There will be scenarios where this setup is logical (like for compute tasks, which you only do on your videocard; like F@H or Cryptomining, if that was still relevant on videocards), but in most scenarios, it would have been better to shuffle your money and put a bit more into the CPU and less into the GPU.

 

I think that is the issue with people screaming 'bottleneck!'. It's a husk of its former meaning. Especially websites like the one you linked do not give the proper information on why something is a bottleneck.

Instead it just recommends the user to get a different CPU or GPU. It does not take into account many people will use their computer for different purposes.

One PC/CPU+GPU combination could be a huge GPU bottleneck in one situation, while in another situation it can be a big CPU bottleneck.

looks at Pentium 4 motherboard, 1x PCIe gen 1.0

 

looks at RTX Titan

 

I know what I must do

Agreed.

 

It all depends on the workloads (if using a 2080ti for machine learning, who cares it runs on a i3).

 

Plus, even when gaming bottlenecks are relative. My CPU (old i5 w/o hyperthreads) was bottlenocking my GPU (2060) by some noticable amount. Bad combination? Nope. Cause I still had a significant boost in fps from that upgrade and later when I went from 1080p to 1440p things balanced out nicely.

 

Next up is upgrade to 3900x likely. Will the 2060 be underpowered then?  According to bottleneck calc,  yup. In reality, "nope" since the exfra speed/threads are for development/running of specialist software and not gaming. Ill then still play the same games for leisure that I do now, and the 2060 already pushes enough frames to my monitors refresh limit.

 

I9900k with 2080TI can form a huge bottleneck (if where talking mining where multiple gpus would fair a lot better).

 

Fit for purpose, thats where its at. A bottleneck only surfaces in specific workloads, even not all games are equally balanced in cpu/gpu load so any system will have some margin of it.

 

That all being said, I really do need that future 3900x to keep my cpu usage below 1% while moving the mouse at 144hz to click minesweeper (which is grossly overdue as far as its rtx enabled update goes, Its 2020 for crying out loud, we should have reflecting mines by now...)

No, it is you experience using it that matters, not a bottleneck.

 

if you get the experience you want at a price you can afford then it doesn’t matter.

[BetteBalterZen]

Does Bottlenecking matter?

 

Uhm yeah, unless you don't care about money

[krakkpott]

I'm running a 2400G with a 1070 and I have yet to see any bottleneck at the moment.

[Tristerin]

For the non-tech enthusiast a bottleneck isn't a big deal.  For a tech enthusiast who enjoys eeking out the performance of his machine/s - bottlenecking is a big deal.

 

Bottlenecking is also a big deal if your machine makes you income.  

 

Bottlenecking bad, and if not bad, than your use case doesn't care and that's okay too.
