RTX 3080 with i7 9700k

[NobleMeteor_]

Will RTX 3080 bottleneck i7 9700K I've been playing some games that I'm noticing that I'm not getting 100% GPU utilization and 1440p ultra max settings with ray tracing on far cry 6 and a few other games

Might get a quicker answer here.

You've answered your own question really.

Yes, it will.

Unless you're pushing 4K max settings it'll be the CPU doing more work at lower resolutions.

OK so what processor do you recommend?

[Muppet among Puppets]

Is the cpu on 100% then?

How much % is the grafic?

[NobleMeteor_]

no oddly enough gpu is usually 93% and cpu 60-70%

Then there is no bottle neck

On 1440p upwards its a completely fine combination.
Only on 1080p will that CPU reach its peak before the GPU and thus bottleneck.
And even then its just at very high framerates.
No reason at all to switch that CPU at the moment unless you really want to.

ok perfect thank you id prefer to save the money.

[Q6871]

good

[BitWBlade]

This is a bottleneck even at 1440p I have same combo

Far Cry 6 is very CPU intensive. It even puts the fastest CPU's to its knee's. I think only at 4K you can remove the CPU Bottleneck.

If CPU not hitting 90% ~ 100% then it means not bottleneck.
If GPU not hitting 100% then it means it not working to it fullest.

Now depending on the game in question, this may come down if this is a game engine issue, rendering issue, video driver issue, overheating issue which you notice like low FPS all of sudden, freezing, or stuttering, and if you're using Vsync, or pushing target frames limiter.

This tell me CPU not limiting your GPU, and GPU not working to it fullest. Also have i7 9700k so don't think you be bottleneck if playing at 1440p to begin with.

Software is written in threads. A bottleneck can be be caused by just one thread not running at maximum. If that occurs the other cpu threads can never be used at 100%, resulting in an overall cpu usage of less than 100%. Yet the cpu is running as fast as it can.

Plus, the I7-9700k is a 8-core but without hyperthreading. The lack of HT will cause less than smooth performance. This is well known from old i5 versus i7 performance studies. It is possible, even likely, that the 93% gpu score is a result.

The performance scores of an i7-9700k are quite low as well.

Integer Math 42,081 MOps/Sec
Floating Point Math 35,810 MOps/Sec
Single Thread 2,893 MOps/Sec

Compare the i3-12100 (4c, 8t) -

Integer Math 42,230 MOps/Sec
Floating Point Math 32,776 MOps/Sec
Single Thread 3,553 MOps/Sec

It will outperform the 9700k because of its superior single-thread speed.

Now, if someone had asked is my i3-12100 bottlenecking my rtx3080 I reckon the answer would be a unanimous yes.

Since Intel tried the non-HT trick and failed, all its cpus have included HT.
