Question 5820k and RTX 3080

Jul 30, 2020
I want to get the eventual RTX 3080 Stryx

Will my 5820k bottleneck it at 2k or 4k?

I game on a 4k TV because I don't have enough space for a good monitor and TV in my student dorm. So refresh rate I assume on 4k is 50hz


More than likely the cpu be fine supplying the graphics card at least 50 fps at 4k. That's just being conservative. We'll know more once benchmarks are out and scenarios like this are tested.

Cpu sets the fps limit and graphics card renders the eye candy. If 5820k can manage 100fps in 2k without being overwhelmed then it'll do 4k in the same amount of frames with a faster card. Lower the resolution (1080p, probably 1440p too) = more cpu frame pre-rendering expected, so an older or less capable cpu is to struggle, reach maximum usages.

Id say your processor will be fine. At worst, a placeholder. See how it goes.


If you are maxed at 50 HZ anyway, I'd concur you are probably ok...

However, if the upcoming 3070 is but $499, and (rumors/claims!) roughly equals/exceeds the 2080Ti's performance, that might indeed be an interesting less expensive option as well...

Looking forward to seeing this 3000-series of GPUs compared with a variety of processors, from 5820K, 7700K, etc. and on up the scale!


Ambassador its not update with the 3080 cards but will be soon but using a 2080ti it wil bottleneck
That is a very poor site and in no way is accurate.

A statement that is right on the site.
