4070Ti + i7 9700K in 1440p bottleneck?

[Flugeo]

My CPU usage almost never goes above 40% in games but there are weird moments like in Ready Or Not HQ when I got low fps and stutters with cpu at 35% and gpu at 40%.
So I got 2 questions:
1. Is CPU’s usage supposed to be low (so 50% is like 100% for GPU with any usage above 60% being something extreme you don’t want for too long)?
2. How credible are online bottleneck calculators if e.g. they show r9 5800x3d being worse for gpu intense purposes than r9 5900x?
P.S. My questions could be formulated wrong so I’m curious for any explanation of how cpu/gpu balance works

1. The CPU will only be used as much as it needs to be.
2. Utterly noncredible. And I am not talking about specific bottleneck calcs, but all of them.

1. any usage is fine, it's temps you want to worry about anything above 80-85c on your cpu is
abit hot (but totally within spec) you really just don't want 90-100c

generally speaking it's better to have gpu usage at 100% vs having cpu usage at
100%, but that's just because a gpu is alot easier to upgrade over a cpu.

also
tons and tons of games ether hardly use or straight up don't use hyperthreading.
some games wont even use all cores, only a portion
others can use everything your cpu has to offer

it depends on the game or application.
some games wont be able to utilize everything you're cpu has
ready or not may only be a quad threaded game
making the other 4 cores you have useless for the game itself

2. i don't really have any idea's as it's almost always easier to
just youtube "X GPU and X CPU on X game"

30% rather much.

https://www.cpuagent.com/build-compare/intel-core-i7-9700k-vs-intel-core-i9-14900k/summary/nvidia-geforce-rtx-4070-ti-vs-nvidia-geforce-rtx-4070-ti?res=2-vs-2&quality=ultra-vs-ultra&ram=32-vs-32&ramspeed=4000-vs-3800

6.3% i think thats a low estimate.

if your cpu is 100% used when gaming (or 1 core is as most games wont use all cores) while your gpu is not 100% used.. you can be sure its your cpu limiting fps.

same with gpu and ram.
the part thats used 100% thats the bottleneck.. so just look or monitor during gaming what happens to your system.

those calculators will be tested on speciffic games the ones you play are different. also more rare models like very high end cpus that few users pick the 1000+ euro ones.. tend to be miscakculated more than very common models.. sample size is certainly an issue.

but if multiple calculators say you have a cpu bottleneck only disagreeing by how much.. you likely do have one.

[_I_]

to see if its gpu bottleneck, look at gpu usage, if its 90+% then its limiting it

to see if the cpu is bottlenecking, lower res and/or visual settings with vsync off
if the fps does not go up, then the cpu is most likely holding it back

you cannot look at cpu usage, or even core usage, most games do not need all the available cores, and windows does a good job at leveling core loads, games will rarely max a single core

there is no 'balance'
if there was no bottleneck (anywhere) fps would be infinite, with vsync off, each sub pixel would be from its own complete frame

ht is 2 cores sharing a single fpu
like 2 workers at a desk sharing a calculator
they can do similar tasks better, any calcs done are saved in cache, if both workers are doing similar stuff, many times the results from one operation make the other not need to use the calc

I have a 9700k with a 3080 playing 1440p. I just picked up a 7800x3d because the 9700k can struggle in a lot of games I play especially esports titles to get the most of my 3080.

Games like The Finals can eat up almost 100% cpu usage and only getting 100fps at 1440p low.

Im just picky with fps though and majority of AAA titles will run fine with a 9700k but you will get more fps and better 1% lows with a faster cpu.

I wouldnt trust any online 'calculators'. Best thing you can do is find a youtube channel or reviewer who has consistent testing method and have data and benchmarks of many combinations of components. Like how I use it to compare 7800x3d vs 13900k vs 5800x3d vs 9700k etc and I can see Id get almost 2x the fps in CS2 just by changing my cpu
