What is bottleneck? How much effect does it have?

[dwl2234]

Hi,

I have Strix X570 E gaming and a 3600 on it. I was using a 1080ti no issues ever. Now I plan to upgrade to 3080. How does bottleneck effect me.

 

I have a 1080p 144hz monitor. should I bother?

 

Senarios.

1------>  I only have 144hz monitor. how much drop will i experience is it like 5-10? And in what range say 3600 fetches me 120FPS and 3900x gets me 150FPS, my monitors is just 144hz its G sync enabled.

 

2------> I can Dynamically scale to 1440p will the FPS drop still exist?

 

I am confused by the articles around. 

 

I only play to experience graphics and more smooth gaming not a competetive gamer. Other than that I train ML models hence I am going with 3080. I pretty much know that strix x570-e is a beast just curious about my CPU?

 

Please explain in both senarios.

at that res yoru pcu will bottleneck the 3080.

 

Bottleneck occurs when there is a restrictive element holding back the performance that could otherwise be achieved. in your case your cpu.

 

bottleneck has nothing to do with fps drops.

what exact monitor do you have? at 1440p there shouldnt be any bottleneck

Bottleneck is always a thing in systems. 

It's the weakest link in a build. And some workloads are GPU Bottlenecked and others are cpu. 

Wait for ampere to actually launch and check how the 3600 holds up with a 3080 but I'd say it shouldn't be bad though and at higher resolutions it should be a nice pair.

Mine is MSI G241C.

Performance as in? there should be scale right. I have never overclocked my GPU not CPU. Never behind Benchmark scores nor behind overclocking. As I said I am only for vanila out of the box experience. (May some rgb tweaking which massively boosts the performance of pascal to Amphere (hehe).)

 

Please comment on th gaming and DL workloads alone.

I play on 1080p screen In india 1440p with a good srgb is nightmare to find and buying one will cost almost the price of my mobo.

you dont determine a bottleneck through just guesses based on hardware in a machine , thats not a thing

without looking at the usages on the machine while under load you can't determine a bottleneck especially when you have no idea what the load is.

I'm not sure why they would tell you you have a bottleneck as they dont really know what exactly you're doing with the machine , what games , at what settings and how those game effect your machine.

But it shouldn't be too bad. But again, wait and check.

Games like:

 

All on Ultra Maxed out (obviously)

 

Cyberpunk 2077 will be playing as I have preordered it already.

Wolf YG etc etc

 

DL workloads:

training models cant write them here as different papers have differnet models.

People wrongly think that by getting a stronger gpu and thus creating a "bottleneck", the performance will be lower, which is wrong. By adding a faster component, the performance will always be better.

Let's take your example. Say you have 100 fps now in a certain game. You get a 3080, your fps becomes 130. But now your cpu is the weakest link, "the bottleneck". That doesn't mean the performance isn't better, it just mean that if you now replaced your cpu, you'll get 140 fps.

I'll just say no to that. In fact supposedly flight simulator is giving top end rigs a run for their money so I'll just say regardless of the machine you plan to use that this game isn;t going to run great on anything currently

Isn't Flight simulator overly demanding as opposed to Cyberpunk which has certain limitations as number players still using 10series and all.

Flight simulator can be run at lower spec easy , but at max setting it loads a machine down quite heavily. Same as 2077

Ya max out on 4k might cause issue what about 1080p and 1440p?

the 3600 starts bottlenecking some AAA games around 85-90fps, it's 5-10%~ compared to a 10600k/10700k/9900k etc. i'm expecting it to be 10-15% for 3600+3080, it's nothing i'd upgrade over but i no longer look at zen 2 for new builds. Just think of it as the diff btwn zen 2 and zen 3.

Ok. so will look at zen 3. once they arrive id they fit my budget. obviously will aim of 4600 not more than that. As I dont need more cores.
