i9-9900k: A bottleneck?

Afternoon, all.

My current rig is sitting in the garage unused. Thinking about wiping the dust off of it...

Current rig:
Asus ROG STRIX Z390-E
i9 9990k
32GB
4TB M.2
3080Ti

Is the i9 a limiting factor/bottleneck in modern games at 4k? I would expect >100fps whenever possible. Am willing to upgrade GPUs assuming the i9 is not a limiting factor. If this is a case, what's the most cost effective GPU upgrade with games such as BF6 in mind?

Thanks!

The i9-9900K performs on par with the i9-11900K for gaming, which is about 10% slower at 1080P than an overclocked i5-12600K, which I have, and is also on par with a 13600T/13600K at stock. However, at 4K, the difference is less than a percent. I'd say you're fine for now.
 
Depends on the game what kind of FPS you would get but the 12900k did give me a good uplift over my 11900k when I switched platforms at 3-4k resolution. I have a 9900k/3080Ti combo from spare parts at work and it definitely shows its age compared to my ryzen 7900x sitting next to it, takes ages to compile shaders, runs a lot hotter, etc. in addition to lower fps.

I don't have any newer GPUs than 3090 so can't compare any newer ones but upgrading my platform was worthwhile for me.
 
I'd say wipe if off, get some canned air, blow it out, and try it first. Just looking at some test reports and a 3080 can run BF6 on high at ~90 at 1440p, so add a little DLSS and a 3080Ti can probably manage 100 at 4k. My limited poking around didn't turn up any 9900K results, but apparently a 10600k can get up to 100 so it'll probably be about there.

If you want 4k native max settings in BF6 at 100+ it looks like you'll need a 5090.

As far as GPU upgrades go I wouldn't bother with less than a 9070XT or 5070Ti. Maybe a 9070. 5070 just isn't that much of a bump up and doesn't get you any more vram. 12GB is ok for a $250 Intel ARC B580, but it holds back the 5070.
 
Looking at the GPU usage %, and if it does not stay about 99% can start to look why (is that particular game an issue, v-sync on with a low FPS, or cpu not strong enough)

4k on a 3080 for new game you would not expect the CPU to often be an issue but if you use low setting to try to go in the 3 figure FPS maybe.. but it is relatively easy to try and look if the GPU does not get fully used, before thinking about upgrading.

For a replacement to a 3080 (which is still a solid gpu), hardware unboxed did a good gpu and cpu test:

If you want to play 4k native at high setting, probably want a 5080/4090 type of gpu.


10900k seem able to reach 100 fps, 10600k can have an hard time to do it at high setting
 
With DLSS being a great option in most games, the i9-9900K might end up limiting your 3080Ti if you're upscaling.

If you're only running native 4K, then it shouldn't be much of a bottleneck. Either way, I'd save your upgrade money for a CPU/Mobo/RAM upgrade.
 
in bf6 it should be fine, as long as you dont expect 4k/ultra/240 or something stupid.
start saving for your next full upgrade.
