Bottlenecking?

post #1 of 5
Thread Starter 
Back when I first joined with my first build, which has long been upgraded,
I was curious.

What exactly IS a bottleneck? Is there anyway to find out what is wrong with it?

What sort of performance can you expect from a bottleneck, could I be getting more from my system, am I bottlenecked?

this question again... Bottlenecking occurs when you have two unbalanced components such as a GTX 580 and an Intel Celeron in the same rig. The CPU is preventing the GPU from running to it's full potential. You can see this by simply running MSI Afterburner during gaming and if you don't get 99% usage out of your GPU then you may have a bottleneck but it could be something else too.

[Edit]
You shouldn't have any sort of bottleneck in your rig.

So essentially running a weak processor and a powerful video card will cause a bottleneck? What happens during a bottleneck?

Does the same rule apply reversed? A powerful CPU and a weak GPU?

Your system will run fine with no bottleneck.

A bottleneck for an extreme example is say you have a core 2 quad q6600 @ stock 2.4ghz and you go and buy a brand new gtx 590 graphics card, the cpu is not quick enough to send the information to the gpu so the 590 kind of just sits there underloaded all the time.

Same thing happens with a monster cpu and an old gpu, gpu is the bottleneck as the cpu is throwing info at it butthe gpu just cannot keep up
