What is bottle necking?

[kingdonut239]

Me and my friend were talking about how my pc would bottle neck if I were to install my gtx 1050 ti. He was telling me that bottle necking would mean the frames would be nothing near constand and would continuously fly up and down. From what I have learned, it would mean the pc would just be help back from frames but not jump to very different numbers numerously.

What are your pc specs? Unless it is a very old system, 1050ti is not fast enough to be bottle-necked by any newish system.

He is wrong. Bottlenecking means something is holding back the performance. You want your videocard to be running at close to 100% in games. Now if your videocard is only running at 50% and your cpu is at 100%, then the cpu is bottlenecking the performance of the videocard because the cpu is not feeding the data fast enough to the videocard and the videocard is sitting idle half the time.

Frame rate can be smooth when it bottlenecked, doesn't have to jump around. It's just lower than it could be.

Your friend is wrong, bottlenecking won't cause fluctuation wildly.

TL;DR - bottlenecking is the weakest link. If you change a component, it can change where the bottleneck is in the system.

All machines have a bottleneck at some level or another.

Example: You have a system that plays well. Say, a 1920x1080p monitor limited to 60Hz, a relatively modern processor (say i5 Coffee Lake), and a GTX 1070 video card. You always have Vsync on, and you have max details set in games.

At this point, the monitor is the bottleneck, because the rest of your system can deliver frame rates faster than your monitor can manage.

Now you upgrade to a 4K monitor and leave everything else the same. At this point, the graphics card is the bottleneck, because it can't manage to deliver enough to run max details at 4K resolution and 60 frames/sec.

Picture water flowing through a bottle . . or say a tube that constantly changes circumference along its length. The narrowest point is the bottleneck because it's the greatest restriction.

Nothing more.

Yeah thats going to be a majore bottleneck right there. In reality that 730 might even get held back by that cpu already in some games.
