8700K & 3080 Is A Joke

[armycombatvet7]

Never seen a bottleneck soo backwards before. Got a brand new RTX 3080 this week and had my 8700K for the past couple years. Ran a 980Ti off of it and then a 2080. I install my 3080 and boot up Windows, open up New World and my frames dropped dramatically in 1080p. Bumped it to 1440p and my frames go up, then 4k my frames go up even more. How is this even possible? I can no longer game in 1080p in most of my games anymore with this pair so I had to buy a 9900K and hopefully that solves my issue.

nvda driver overhead, on ampere it uses more cpu per frame, problem existed in turing too.

 

As for the 9900k, it'll solve most of it, but not all.

As a 9900k owner I can confirm it does still bottleneck a bit. Over clock all core to 5ghz helps a lot.

I would of never thought this would happen, I thought CPU bottlenecks were very rare in 2021.

I didn't think the i9-9900K will show it's age anytime soon I bought the i9 about 8 months ago, but I never got a chance to get a decent GPU, I bet I should look more carefully for one, and maybe not get a 3080 or 3090, not that I would really need one though.

 

This is informative though.

I have a 9900K with a 3080 and a 3440 x 1440p ultrawide monitor. In almost all games my 3080 is running at 99-100% and my 9900K lower. So at this resolution with AAA games I am GPU bottlenecked. If I played at 1080p I might be CPU bottlenecked in less demanding games but then again you don't need a 3080 to play at 1080p. 

Upgrading to a 9900K might help in some games as will overclocking your 8700K (if you are not doing so already).

I should have been more specific. I am using a 3090 fe (I also do ai dev and video editing) and I only see it bottleneck in some games and if I put it in 1080. Never bottleneck at 1440. So it isn't much of one either. 

My system is also a full custom loop with the gpu having a +100 on the core and +700 on the ram.

they are common but not talked about, some techtubers even stated that if they used the word bottleneck they'd just get nasty comments about it

 

The type of bottleneck thats concerning is high cpu usage causing massive drops in fps (hitting a wall), happened to me with 8600k and op's 8700k

The 9900k is a little bit of that in some games (avengers, certain settings in 2077, msfs). other than that it's just slower than newer cpus, my estimate is about 10% to 10900k and 20% to the 5950x, it's not very concerning with ampere, but when the 4090 comes out, i'm not very optimistic even for 4k, (hoping it's only the 15-20%)

A 1660 super or so is enough for 1440p.

That's something I forgot about, now that makes sense.

Yes, don't need the 3090 for having really either. If it wasn't for the other work I do with it, wouldn't have got it. But considering msrp for many 3080 ti cards is over 1500 I am not regretting it at all.

Why did you get a 3080 for 1080p? Are you pushing a 240hz or higher monitor

I retired my i7 8700k when I upgraded to a RTX 2080 ti for a GTX 1080 ti. It could not do 5ghz all cores and without 5ghz it was left behind buy my i7 8086k that could. They both did about the same frames with a GTX 1080 ti so it was a bit of a shock when the 5ghz 6 core did 10 more frames in some games.

 

I did build a i9 9900k computer at the beginning of 2019 but it went straight into productivity with 2x 1080 tis. I stared using it for testing this year to compare it to a 5800x and it can keep up in most games and even win in some with the same 2080 ti. 

 

The i9 tested a Strix 3080 and now a FTW3 Ultra 3080 ti and it did fine. It will end up with a EVGA XC3 Ultra 3080 ti that my 5800x is using now so it will be interesting witch one does better. 

 

The i9 9900k is definitely the way to go with a Z390

I had plenty of trouble with my 8700k with a 1080 and 1080ti. Really didnt wonna upgrade cards unless I got a new rig and some fancy 1440 monitor with actual high refresh rates.
