How much will a 8700k bottleneck a RTX 3080?

[opethdisciple]

Asking on behalf of a friend.

He has a 8700k and plays at 1440p.

How much if any would a 8700k bottleneck a RTX 3080?

Really I'm referring to next gen titles such as Watch Dogs Legion or CyberPunk for example.

I know we can't answer this fully until tomorrow at the earliest but if you had to take a guess what would you say?

Less than my 4790k

Depends on how those games behave and what there CPU use is like.

In general can get an idea of how they perform by whacking down the visual settings and resolution to make the CPU the primary boundary and see what sort of FPS it pumps out. Of course impossible with those games mentioned but suspect he will be fine.

I will be using the same CPU OC'd in my HTPC and also going 3080 or 3090 and expect my limit will still be the GPU in those games with eye candy cranked up with maby some scenes CPU bound. Just crank give it an OC and it sits right up there with latest out (not surprising seeing as Intel just bolting on more cores) Games around 6 min mark.

I'll be using a 3090 on a 7700k until new Ryzen is out (assuming it outperforms a 10900k). Ultimately you will be giving up some frames, but you can always upgrade CPU in the future. I bet the difference won't be big at all. More so on the lows.

Assuming it is clocked up to near or around 5Ghz it will basically perform on par to or within margin of error of the 10600k.

We don't know performance in those new titles yet but I can't imagine a 8700k would be a horrendous bottleneck to the point where it made the game unplayable, especially at 1440p.

Assuming it is clocked up to near or around 5Ghz it will basically perform on par to or within margin of error of the 10600k.

It may even be slightly faster than a 10600K, which has worse inter-core latency due to it being a 10-core die with parts disabled.

An 8700K isn't going to be holding anything back any time soon unless you specifically set out to make it do so by running your shiny new 3080 at 1080p Low.

AFAIR a 4790k @ 5GHZ at 1440p is AVG of 8% Bottleneck dependant on the games so will be less.

I am in the same boat seeing that I've got a 5960x paired with a 1080ti, what I will be doing is to upgrade the gpu first and when AMD releases new cpus I may change the cpu+mobo combo.

not as much as most people think

That is the sensible way to do it.

Your friend will find out when he gets the 3080. If he needs an upgrade then he can upgrade.

 

[Nbuilder]

IF he gets the 3080

So basically at 1080p ultra the 3900x is 15 fps behind. Overclock it to 4.3 ghz with very fast tight timing on the memory and we see what? 1 % difference.

And BTW, far cry 5 is a joke on ryzen cpu : optimised for ryzen my ass. Can't believe they didn't update that engine or game already.

thats a really good review thank you! second hand 7700k seems the best bang for buck option from a 6600k rather than complete new build based on that

Watch these videos.

 

[Chaos666]

8700k is still very good gaming cpu... especially overclocked... sure more cores with 10900k is better .. but not always and not by a lot

 

[Shonk]

If its overclocked it doubt it will make much diff
my 9900KS is never fully loaded not even 50%
most games its around 10%-30%

its fine.
