Do you get bottlenecks in Intel CPUs that overclocking actually solves?

post #1 of 8
Thread Starter 
I'm trying to figure out if a i7-4770K would be a benefit to be overclocked in current gaming. If it doesn't bottleneck anything anyway what's the point right? The FPS won't increase anyway.

So, do you have experiences that show if you didn't overclock, you'd actually have a problem in gaming?

Depends on your configuration, I had a 2500k coupled with a 460 2Win and it had no bottlenecks at stock clocks.

Depends on application used for and also resolution can be a large factor.

I wouldn't say it would be a bottleneck at stock but I get more FPS in games at 4.5 than 3.8. Especially in Planetside 2, BF3, and Skyrim. Free performance, why not take it?

Doubtful you can effectively bottleneck a single gpu + 4770k system, but as you add 2+ gpu's, you will eventually be hindered back by your cpu, in which case overclocking can bring the extra grunt you need to balance things out.

In most cases it will, more or less depending on the game. Overclocking is equally worth it though even with a single gpu, as some games out there utilize the cpu more than others, and can give you a nice boost.

Really depends on the game. For WoW in large raids there is a difference between stock and 4.4ghz. I imagine other more cpu dependent games would benefit as well. With large battles in BF4 I'm sure it will help there to.

While a limited phenomenon, I guess I missed the point that even if the GPU(s) may not be bottlenecked entirely, the CPU can still inflict some base latencies that when they are minimized can always give a minor improvement.

A Good analogy is PCI-E lanes. While a few lanes don't "bottleneck" a card since after all most of the transactions are done between the VRAM and the GPU, they still offer a benefit the more they are, even if minor, just because they reduce the base latencies of communication of the card with the CPU.

Overclocking my cpu made a huge difference in Planetside 2, and playing mmorpgs. It also helped on certain occasions for BF3, but it ran pretty much past 60 fps on stock clocks anyway. It really depends on games. GPU overclocking on the other hand is pretty much beneficial to every game that I play. Having those extra 5-10 fps can be really helpful.

It will help every time. CPUs are really slow these days once you cranks up GPU power. Even so most games that are a bit old use only 2 cores and you need those cores to run as high as they can. I was playing BF3 @ Stock and i could easily tell compare to 4.6GHz OC. Wanting 120fps/120Hz. You will need every MHz that CPU can get you.
