understanding the term "bottleneck"

a FX 8320 @ 4.2 GHz and GTX 970 SLi...

 

with my i7 my FPS in WOW were 140-160 in raid... now with the back up CPU im not even breaking 75... is this what is called "bottleneck"? avg FPS is 50

 

back up MoBo is sabertooth 990x r2 on a 1440p 144Hz monitor MG279

basically.

a factor that limits a substantial amount.

Yes.

The term bottleneck comes from ye olde English word bottleneck, coined in the year 1528. This basically can be summed up by the phrase "Something is making my shit slow". This can then be better defined by a car with too many killowasps that has no traction or trying to run a brand new SATA3 SSD on a SATA1 port.

 Yes thats exactly it, your 8320 cant supply the information your GPU's require fast enough so slowing everything down. You should also see that your GPU's will have a smaller utilization %.

 is this what is called "bottleneck"?

Yes.  Every application will have certain requirements, each corresponding to one (or more) components (a CPU, GPU, RAM, etc.)  Whenever all but one can handle the load fine, but one is being maxed out, that component is the "bottleneck", or can be said to be "bottlenecking" the system because if it was faster, the program would run faster (because the other components are not yet maxed out).  In reality, there will always be a bottleneck, but convention is to assume that this is/should be the GPU, and if it is not, you should upgrade so that it is

ok thank you all. should i pull out one card until i figure out my mother board dilemma?

A "Bottleneck" is where something is limiting something else. (sorta)

 

Like how the neck of a bottle limits how much of whatever is inside the bottle can flow out, or how much can be put in in a given amount of time.

 

If your CPU is crappy, and you're trying to run a CPU intensive game, your GPU is going to be limited by your CPU as it's not good enough to keep up.

Quite simply it is a narrowing of efficiency or effectiveness within a system. Like the neck of a bottle.

I have to cringe when I see builds like that. I wont be upgrading GPU from my build, either AMD Zen or Skylake.

the CPU and board are spares/ back ups... i have no choice for now

 

i get the term bottle neck but wanted to make sure i fully understand with the parts I am using right now and how it affects me in game

[anthonyc813]

would anyone box one of the 970s? since its really adding nothing, might as not keep it running I guess?

Yeah I think so.  Until you get a proper CPU again no point in keeping electricity flowing through that card

ok thank you
