Bottlenecking and CPU/GPU correllation

Recommended Posts

Posted · Original PosterOP

Hey!
I have been wondering and researching a bit but couldnt find too many answers on this topic so I want to hear your opinions!

I was wondering: Is there some kind of correlation between the TIER of GPUs and CPUs?
I mean, if I was to use a 3090, how do I know what CPU to choose without finding the GPU unable to get through the bottleneck?
Is there a rule-of-thumb?

I was planing to save up for some time and get a 3090 at some point early 2021. What would be the LEAST I should get in the CPU department? (107xx; 108xx; 109xx?!?!)

Any kind of answers and research appreciated.

a 3090 would be fine with a 10700k/10900k, but would be better if we get benchmarks with zen 3, you can get the fastest cpu for the 3090 and there would still be a bottleneck at 1080p and 1440p, but at that point there's nothing better.

 

you can estimate the cpu bottlenecks to the 3080 with the benchmarks here

If you're solely using your pc for gaming, then the best thing you can do is googling reviews and check gaming performance videos on youtube for all the combinations you might be interested in.

 

With that said, for gaming at 4K, the GPU is usually the bottleneck. For instance, with a 3070 you'll get fairly good results with even a current gen Ryzen 3. On the other hand, if you can afford a 3090 you might as well not cheap out on the CPU and get a Ryzen 7 or a Ryzen 9.
