How much will my system bottleneck the 4090?

[rippy4500]

Im getting the 4090, will my system work well with it?

 

Amd r5 5600x 4.75ghz (smt disabled)

noctua nh-d15s

trident z rgb 3600 cl16

gigabyte b450m ds3h (need to replace with standard atx mobo to fit 4090)

evga 1000 t2 psu

phanteks p400a case

arctic p12 fans, 3 intake, 2 exhaust

windows 10 home

windows is tuned very well, no background tasks and lots of tweaks to maximize both cpu and gpu performance. Its a little bit faster than a regular system, not by much but the difference is there.

 

I am wondering if my system will support the gpu and work without any issues, and also have minimal bottlenecking.

 

Using 1080p 280hz, I play most types of games

Between zero and 100% depending on what you are doing and what resolution you are using.

I have no idea, but you fail to mention resolution. In 1080p you will be CPU bound regardless.

In 1440p/4K, you're more GPU bound, in which case whether your CPU would bottleneck or not would depend on the game. 

I mean recent games would adapt better with multi cores right, but older games you'd want fast single core instead of multi core. 

For example, my 12400 usage is very high in spider-man remastered, touching 90% at times, that is with an RX 6800 XT and RT High. I'd imagine with 6900XT or 3090 Ti, my 12400 would be maxed out, which would make it CPU bottleneck. However, in SOTTR ultra everything, my CPU barely hits 30%, so no bottleneck here.

 

To sum up, there isn't a single correct answer, it varies on multiple factors and situations.

Im playing at 1080p 280hz, res is low but its high refresh rate. And my cpu Is still pretty decent so I might still take advantage of it pretty well.

 

I play most different types games so It will work great sometimes but other times not as much.

In that case, 4090 is a waste of money. People with 3080s have huge bottleneck in 1080p, either they are CPU bound or resolution bound, imagine a 4090.

That's why I said between zero and 100%. Unless you do one thing, it's going to be impossible to give you a number with any meaning. I have a 2080 and a 5600x, some games I am cpu bound, other games I am gpu bound. There is no one answer.

Most likely yes. Will it matter? Unless you refuse to crank graphics settings to give the GPU the disadvantage (you want the CPU to slightly outrun the GPU if possible), probably not. Benches aren't out yet though, so no idea if PCIe 3.0 will make things funky, but you shouldn't need a new mobo unless that's an issue. Unless you have other PCIe cards you need to keep in the system or a USB 3.0 header in the way (those cables are really tall and nigh inflexible near the connect), no reason an mATX motherboard can't use a *whatever slot your case can physically fit* card.

Yeah but do you think im gonna have the same cpu and monitor forever? If I downgrade my gpu I will regret it when I eventually upgrade my hardware. Its a bottleneck for now but probably wont be in the future.

I need a new mobo because the 4090 will interfere with the front panel connectors on my m-atx board. Not because of any feature sets or anything.

Ah ye then RIP, I'd look for a B550 when you get the new one, to skip PCIe 3.0 being a problem. The 3090 got choked by about... 3% on PCIe 3.0 x16 at 1080p low with a very fast CPU (was like a 1% diff at higher resolutions). If the 4090 is near as fast as it's supposed to be, then it could see a noticeable hit on PCIe 3.0. With your CPU now it might not really matter anyways, but you have a clear path to the 5950X/5800X3D later down the line unless you're planning to switch platforms by the time you want a CPU upgrade.

Im skipping current gen cpus, ryzen 7000 isnt a big enough jump, neither is 5800x3d. I will upgrade to ryzen 9000 or intel 14th gen, thats a long wait but its not like my 5600x is bad, it will still be enough for now even if it does bottleneck.

280fpsnis not possible in a lot of games as they arent optimized enough to eveb get that high.

 

At 1080p even a 3090 can max out every single game that isnt a hot mess (a 4090 wont change that). Its beyond overkill for you.

 

A 5600x is gonna push well above 140fps but its only gonna fo your target fps in esports games and very optimized ones.

 

So basically just get a lower end card you wont see a difference as you play at too low of a res.
