Same GPU different CPU, does it effect gaming perfomance ?

Question

so let s say i have two different pc with same built except for the CPU (i3 4440 vs amd kaveri a10 7860k). My GPU is gtx 750ti. Both of the CPU will not bottleneck the gtx750ti, but have different processing speed and etc. will it effect gaming perfomance ?

Answer 1

Most games are GPU limited these days, so either processor should be fine for those games. For those few games that are CPU-bound, the Core i5 will do better, slightly, but games like those often have good multithreading support (unless they are simply poorly designed), and will probably distribute their computing needs across the different cores pretty well. In a case like that, the Intel will still do better, but difference will be much less.



Also in the case of the AMD, why bother getting an A10 7000-series when an Athlon X4 800-series will offer the exact same performance (exact same cores), for half the price? Since you're going to be using the 750 Ti anyways, there's no need to get the AMD with the embedded GPU, it'll never see action.

Answer 2

To answer your question.

If you are playing a CPU heavy game, the i5 would do better.



If you're playing a game with detailed graphics that maxes out the GPU then you wouldn't see a difference.



My favorite types of games would bottleneck both those CPUs in that setup.

.



But, to try to explain a few things for you:

If you just Googled "i3 4440 vs amd kaveri a10 7860k" you can see the performance difference. Basically saying the i5 is 30% - 40% faster.

A bottleneck is the part the system is waiting on. When you load a game, it's the hard drive. When a game has complex mechanics (like a RTS) it can be the CPU. When the game has fancy graphics (like a FPS), it will probably be the GPU.



So, you'll only see a difference if you're playing a game that is waiting on the CPU and isn't fully using the GPU. You can use tools like GPU-Z to watch your GPU usage.

Answer 3

I haven't seen anyone talk about the possibility of a CPU bottlenecking the gpu yet. This is possible, ithe would most likely only NOTICEABLY cause you issues if you were running an i3 and a Titanx for example. Most gpus/cpus don't have said issue but it's possible for sure.

Answer 4

dunno

Answer 5

There is no i3-4440. 4th gen i3's only go up to the 4370. Perhaps you mean the i5-4440. If so, the i5-4440 has much better performance per core, which means that it's overall performance for any application would be better.

Clock speeds aren't as important as core performance.

Answer 6

Maybe slightly in favour of the Intel
