Can a non-bottle-necked system have better performance than a better bottle-necked system

hey thanks!

I recently put a Gt 1030 into a 6 year old Pentium G630 PC and I immediately ran into bottle-necking issues as my CPU was bottle-necking my GPU as the GPU was only at 25% while my CPU was at 100% when playing games. My question is can I get better fps with a much lower end GPU that doesn't get into bottle-necking issues with my CPU and can it be solved vise-versa?

Every system has a bottleneck, question is at what load.

 

If your CPU is bottlenecking, then getting slower GPU will not increase your FPS. In fact, it could decrease it when GPU becomes the bottleneck.

its about the weakest member in the team.

 

the cpu gives your gpu the data is has to calculate images from and if the cpu cant do that fast enough / your gpu is done with that information faster then the cpu can provide more thats called bottlenecking. in your scenario the gpu is just bored 75% of the time. imagine if a teacher wrote a text on the board for the students to copy but at one word per minute. youd write it down and be bored. now getting a card that can also only write things down at 1 word per minute to stay with the metaphor wont make the process any faster. yes they will be a good team and better price to performance since your not wasting overhead performance but your still going at 1 word per minute.

 

hope this helps to clarify?

There's no such thing as a non-bottlenecked system. Some component will always be a limitation. In gaming systems, you want the GPU to be the bottleneck as in that case you're getting the best performance possible from that system. The CPU needs to be able to "keep up" feeding information to the GPU as to what it should be rendering on-screen. If it can't do this, the GPU must then wait for that information, the system slows down and the CPU becomes the bottleneck. 

 

There are plenty of videos on YT about PC bottlenecking. I suggest watching them before asking more questions on the subject. ;)
