What is bottle neck?

I hear about this when people refering to the balance between the cpu and gpu but I really want to understand that because I'm planning buy a gaming notebook. I hear some people saying the a T7700 2.4ghz is too much for 8700m while other people say it will be good for a Go 7950 GTX and viceversa but I don't understand. My use for the laptop will be gaming, word, excel, powerpoint, photo and video editing and web surfing. But mainly will be for games. My 2 options are the Sager's NP9261 and the NP5790 either way with the 8700m GT or Go 7950 GTX , SLI enabled on the 9261 or single on the 5790. What will be the best cpu and gpu choice for both models?

 

Applied to this case, there is no point in having an extremely good processor when the graphics card will be limiting how much performance you will be getting rendering some of the processing power useless. This assumes the processor intensive processes you will be using will involve graphics, e.g. games.

 

In other words is pointless get the best cpu with the best gpu...

 

Yea. Think of it like this, a 2L soda plastic bottle, if you turn it over and take off the lid, the liquid will slowly chug out due to the small bottleneck.


If you reflect it in terms of computers, same idea It's not pointless to get the best, if if the budget is only so much, making compromises must be made. For example, for a gaming notebook, the video card is what counts the most, so getting a fast computer with a slow video card results in the bottleneck being the graphics card. Same with using Vista on a 2.4ghz Core 2 Duo with 512mb of RAM, the bottleneck is the RAM.

 

Okay I get it is like get a Honda and put the cold intake system and a header but left the stock exhaust pipe the bootleneck will be the pipe. I use that ex. because thats my field I'm new on computers. In other words made a good balance of cpu and gpu and ram too...

 

basically the 8 series SLI setup right now is significantly slower than a
7950gtx sli setup, some justify it with the dx10 argument, but thats kind of weak considering the amount of dx10 games out, the things the 9261 brings over 9260 (quad core, 8700gt sli) i would consider not worth it and go with a dual core 7950gtx setup for max speed, honestly we're a long way off from having full dx10 games and quad core optimization, so in the next 1-2 years that would be the setup to have , or even single 7950gtx for now and one more later

 

i was so thinking about doing the same thing ^
but i fear the admins =)

 

Okay thats not funny I know what is bottle neck in terms of the glass... But my ? was in terms of computers... Hey maybe I posted wrong I learn english 2 years ago when I join the army at 27years old. Sorry if that wasn't the right way to ask.

 

a computer is only as fast as the weakest component. what ever your weakest component is, that is your bottleneck.

 

I thought the point of the picture was to show that the bottle's neck was what your laptop GPU was in your system's ability to process game information quickly (bottle water flow). It's not an insult into the OP's intelligence though a few explanatory notes accompanying the picture would have demonstrated the point absolutely clearly.

 

Well just to illustrate what others have posted, including the bottle image i have edited an image to show you EXACTLY what they are saying if you are the type of person who likes visuals better than words like me. You see, the CPU is fast, the ram is adequate, but he GPU will slow you down even though you have all that other power.

 

As far as notebooks go, you never really have to worry about bottlenecking the GPU because of the CPU.

The only case I have seen this true is in my own desktop, where my Core 2 @ stock clocks can actually bottleneck the 8800GTX.

Other than that, it will always be the GPU bottlenecking, at least in the present day.

 

Picture should be clear enough for the OP to understand now. For some games like Oblivion having a faster HDD could make a difference by decreasing loading times.

 

Okay but in the way the appear 1st without a explanation I was like Why??? But okay I apologize...

 

It all depends on the game. In RTS's, your performance could easily be bottlenecked by the processor, even with laptop GPU's.

 

That picture explain everything simple.

 

I'm glad my picture explained everything nice and simple for you. If you need anymore help understanding bottleneck and other things you can always pm me.

 

Between the 2 options of notebooks I have, which one you from your experience recommend me?...

 

Send me a pm with more details like which are the two notebooks, and the specs. I wouldn't want you to hijack your own thread.

 

nice one Calvin... I really should have illustrated it better in my picture...

 

As i said, it's not problem. I'm here to help as much as i can, to the best of my ability. Also all i really did was re-illustrate what you were saying so it was no biggie.
