What is a bottleneck?

[overclocker]

Hi,

Do anyone know what is a bottleneck? Is it like a problem or what?

Theres several understandings of bottlenecks
One is, as implied, it squeezes performance, so that all compomemts arent getting their full ability because one is "bottlenecking" the rest.
The other one is, a true bottleneck will adversly effect your entire rig in many/all or a given app.
In the end, theres always a "bottleneck" by one of your components, as that particular one will be the impeding component, not allowing for full usage by the others, and is why some say the true deffinition is a dynamic loss of perf, while it is considered more as a limitation in a balanced system as a norm

Bottlenecks were discussed over in Graphics yesterday. This is the best picture of that bottleneck anyone has come up with so so far.

I like my bottlenecks, and with enough of mine, yours goes away

Incredibally alcohol was involved. This is the guy from over in Graphics yesterday. Here's to your burrppp health.

Bottleneck is where a particular part of your system lowers the total performance.

So let's say you have a kitchen, you have a nice refrigerator, a nice sink, but a terrible oven which burns everything you make. The oven is your bottleneck.

OP doesn't have anything 'nice' except a '62 Falcon. Is that a problem He wants to know.

 

[JAYDEEJOHN]

@ badge, in this case , its best to Dodge darts heheh than to use a Bull Dozer

Oh. Yeah. LOL. 8)

Wonder if thats a funky falcon?

The thing with those falcon's, the funky ones you refer to, they are the weakest link in regards to the Bus. Like the guy in graphics said yesterday, "Hardware bottlenecks are caused by software. It's all weird and creepy like that when life long family problems have ruined your life. Sadly.

 

[JAYDEEJOHN]

I imagine, just as many of his other thoughts, but who needs facts when insults can do?
Well, theres plenty of SW here to make his life just a lil weirder

A bottleneck is an entity which is responsible for limiting the performance of your system.

For example.

Let's say you have two components a Graphics Card and a CPU. The Graphics Card is a brand spanking new ATi Radeon HD 5970 while the CPU is an older AMD Athlon64 X2 3800+.

You've just purchased the new game out on the market and it's a demanding game. You run the game and are getting rather low Frames Per Second (bad performance) even though you're running the latest and greatest Graphics card (Radeon HD 5970). The reason for that is that the CPU (Athlon64 X2 3800+) is acting as the performance limiter, your Graphics card can only process the data it receives from your CPU and if your CPU cannot keep up with the data coming from the game.. your whole system slows down. The bottleneck in this example was the CPU.

That is a bottleneck.
