Possible Bottleneck with RTX 5080?

[Jeancly]

Hello Folks,

This is my actual build of 4ish years ago:

-Samsung 970 EVO Plus 1 TB PCIe NVMe M.2

-Silent Wings 3 140mm PWM High-Speed x5

-Be quiet. Dark Rock pro 4 ( with the 2 included fans )

-Fractal Design Meshify S2- Mid Tower

-Corsair RM750x ( so 750 Watt psu)

-AMD Processor Ryzen 7 5800X

-ASUS ROG Strix B550-E Gaming

-RTX 3080 OC Gygabyte 10 Gb version.

-corsair vengeance ddr4 8 Gb ram stick x4.

I'm using a simple fan hub to connect all the non cpu fans to a single fan header ( yes the hub is powered separately so there should be no issues there)

Leaving aside the insane actual situation with availability and prices of series 5000, if i manage to get a rtx 5080 will i incurr into bottlenecks ? If yes how much ? like, to the point of not making sense getting a 5080 or it's just better than a 4080 either way ?

EDIT : correctly it was pointed out that it depends. i Play at 1440 P ultrawide. Modern games generally ( like i plan to play monster hunter wilds, i play cyberpunk, etc etc )

Depends on the game and resolution.  If you run 4k and newer titles, there will be very little bottleneck.

in a bottleneck calculator you max was 22% with the 4080 for 1080p

good point, added a edit, i play at 1440p ultrawide

every machine on earth has a bottleneck , so yes. No matter what hardware you choose there will be a bottleneck.

Bottleneck calculators are pure garbage. There is no single answer to this question, while calculators pretend there is.

 

Whether you're GPU or CPU limited will vary based on game and individual in game settings such as resolution and detail levels. This is not something you can compress into a single percentage value, without it losing all meaning.

 

Use a tool like Intel PresentMon or MSI Afterburner. Is GPU usage in a specific game well below 90%? Congratulations, you are CPU limited (in this one game!). Does it matter? No, unless the game's frame rate is unacceptable as a result, or there are other issues like stuttering.

i mean, i usually have gpu at 99% with my rtx 3080

Also,just to be clear it's really a matter of " is it worth it " more than , will it bottleneck.

Because of course if i got a better cpu etc it would bottleneck less. But i wanted to upgrade gpu and that's it

what does this reply even mean ? that it would be better with this cpu ? indeed of course.

1) modern AAA with high settings - You will barely lose any performance.  Maybe in some game areas there are a bunch of NPCs, physics, etc.

2) older games that run on a potato - Do you care if you get 300fps vs 400fps?

 

Also, the 3080 is going to hit more and more VRAM walls.  10GB was never really sufficient.  It was *ok* for most things when the card came out.

ok this is an interesting answer, so in short i might bottleneck only for npc stuff and phisics as expected, but the actual graphics etc it will work properly ?

It is hard to tell very likely it will still be higher than what you have now, but it still depends on the game.  I believe I was on a 5950x when I got the 4090 and pretty much everything was faster (at 4k).

i mean yes, the question was pretty much " if i get a rtx 5080 will i be so much bottlenecked that i might as well get a rtx 4080 " ?

Can you even get a 4080 and at reasonable prices?  The two cards aren't much different maybe +10-15% with the best CPU.  Not sure if I've seen anyone testing on a 5800x.

nah, besides the RTX 4080 isnt cheaper then the RTX 5080, and the 5080 unlike the 4080 is an overclocking monster.

Are you just trolling at this point with how many people telling you this is crap?

That means you're always GPU limited (i.e. what you generally want) never CPU limited in any game you've tested. Which is what people would typically describe as "no bottleneck", even if your GPU is technically the bottleneck here. That tells you there's room to upgrade to a faster GPU, while a faster CPU wouldn't help.

 

According to the bottleneck calculator of pc-build.com an RTX 4080 (they don't offer a 5080 yet) would give you a "9.1% bottleneck". What useful info does this number give you?

 

At best it could mean you'd become CPU limited in some games, but it doesn't tell you which games those are and whether the CPU limit in these games is even significant enough to worry about. As long as the CPU limit isn't so bad that games are an unplayable sutterfest, a CPU upgrade is usually not needed or worthwhile.

[ewitte]

Interesting calculation it tells me 4k (and 1440p ultrawide) with a 7950x3d and 4090 is 0% bottleneck (9.1% at 1080p for "general" and 13.4% for CPU intensive games).
