RTX 3090 Bottleneck

Recommended Posts

Posted · Original PosterOP

What's the lowest possible cpu that wouldn't bottleneck a RTX 3090? I wanted to see if I could put one in my potential build but I need to know if I'd need to sacrifice a kidney for a cpu.

All current CPUs bottleneck it at any resolution other than 4K.

 

That may change once the new games come out...


i9 9900K @ 5.0 GHz, NH D15, 32 GB GSKILL Trident Z RGB, AORUS Z390 MASTER, EVGA RTX 3080 FTW3 Ultra, Samsung 970 EVO Plus 500GB, Samsung 860 EVO 1TB, Samsung 860 EVO 500GB, ASUS ROG Swift PG279Q 27", Steel Series APEX PRO, Logitech Gaming Pro Mouse, CM Master Case 5, Corsair HXi 850W Platinum.

budget oriented CPUs that are reasonable for a 3090:

Ryzen 5 3600

Ryzen 7 3700X

Core i5 10600K

 

to name a few, but it also depends on what games and performance target you're after. If you want some 1080p 240Hz gaming, the 3600 might not be able to keep up.


I WILL find your ITX build thread, and I WILL recommend the SIlverstone Sugo SG13B

 

Primary PC:

i7 8086k (won) - EVGA Z370 Classified K - G.Kill Trident Z RGB - Force MP500 - Jedi Order Titan Xp - Hyper 212 Black (with RGB Riing flair) - EVGA G2 650W - Black and green theme, Razer branwashed me.

Draws 400 watts under max load, for reference.

 

Linux Proliant ML150 G6:

Dual Xeon X5560 - 24GB ECC DDR3 - GTX 750 TI - old Seagate 1.5TB HDD - Dark moded Ubuntu (and Win7, cuz why not)

 

How many watts do I need? Seasonic Focus threadUserbenchmark (Et al.) is trash explained, PSU misconceptions, protections explainedgroup reg is bad

USAGE CASE?

RES? SETTINGS?

Lower settings for Multiplayer FPS?

 

Need some basics.


Maximums - Asus Z97-K /w i5 4690 Bclk @106.9Mhz * x39 = 4.17Ghz, 8GB of 2600Mhz DDR3,.. Gigabyte GTX970 G1-Gaming @ 1550Mhz

no, the kidney is for that gpu. a decent cpu would be the ryzen 9 4950x or the core i9 11900k. or, honestly a 5950x or a 12900k.


I am still TechWizardThatNeedsHelp, just less of a mouthfull.

 

My beautiful, but not that powerful, main PC:

My new PC I'm saving for:

  • NZXT H1 Matte Black
    • Comes with a 650W NZXT PSU
    • NZXT AIO
  • Ryzen 5 3600
  • MSI B450i GAMING PLUS AC
  • XPG ADATA 2800Mhz
  • RX480 untill I have more for a 2060 or 2070
  • 2tb Sabrent Rocket Q PCIE gen 3 NVME SSD
  • Samsung 470 128GB SATA SSD

Nothing keeps up at 1080p with a 3090. A 3080 will most likely be bottlenecked.

You are aware that this is a nonsensical question, right? If you're willing to shell out 1499 on a GPU, just buy the best CPU you can get and be done with it. In every other build a 3090 is a severe mismatch.

they all bottleneck, even at 4k, buy the fastest cpu available.
