3080 and i9-9900K bad or good combo

[Graset]

As its says is a 3080 founders and a i9-9900k gonna be a good or a bad build? I resent upgraded my cpu "broke". And i'm wondering if the 9900k is till good to use with the 3080. 

 

Havent seen anything about the i9-9900k.

9900K is an extremely capable CPU and is a wonderful pairing with the RTX 3080.

A 8700k would be fine, no need to upgrade.

Everything faster than a 7700k will be enough.

okey thx guys, would really suck to upgrade the hole pc one more time.

I've only seen this from Jayztwocents, but he noticed that an 8th gen Intel processor is actually bottlenecking even a 2080 Ti by about 20fps. The 9900K though is really close to the 10900K, so I doubt you'd see a bottleneck there.

@Chris Pratt I would not call it bottlenecked, just less fps, which is to be expected, given the slight generational improvement in IPC and boost clocks.

the 8700k especially with an overclock should handle the 3080 just fine, if you're upgrading from an 8700k to a 9900k, it should still be fine.

Depends on the resolution.

Depends on the resolution. If you're playing at higher resolutions it's not as much of an issue. Though I suppose having a 7700k and a 4k monitor is a little unlikely.

Uh....not sure if you're aware, but that's exactly what a bottleneck is.

I would consider some component bottlenecked if said component has to wait for the other component to catch up for too long and thus data is dropped out of memory, creating worse performance than with a lower tier component for example. Sure if you can play and feel 150 fps or more, you may argue it is but at the same time, you could change a setting in game to compensate for that. I'd call it bottlenecked if changing setting does little to nothing for you and you are still only running your GPU 50 percent load for example (which would likely drop the boost speed way below what you would expect and thus slow the card down to the level of a cheaper model, or worse).

if u already have the cpu then wait for zen 3, if you are building new and can't wait, get comet lake instead, overall it should be a minor bottleneck for 1440p. If zen 3 isn't faster then it's doomed.

What you consider it to be is irrelevant. What it is, is a performance drop due to a certain component not being able to reach it's maximum potential.

Which is what you're getting when the CPU can't keep up.

It strongly depends on the resolution and refresh rate you are targeting. At 4k it seems to be a fairly even playing field, but at 1440p you start to notice bigger differences and 1080p is bottleneck city.

I don't think one would have 9900k for 1080p gaming. I did assume we were talking about 4k gaming. For 1080p you would not consider a 3080 in the first place.
