Bottlenecking, lately when I see people build PC's they are always worried about "bottlenecking" or when they get poor performance in a video game they blame their PC having a "bottleneck". The stigma that anything low to mid-range being a "bottleneck" is grinding my gears, "I'm building a PC for gaming, will my 860K bottleneck my 970?"

A bottleneck by definition is: A lessening of throughput.

The mishandling of this term is just driving me mad lately, being it "PC Builders" on YouTube who have sprouted up doing reviews of low to mid-range parts and will throw the term "bottlenecking" to try and scare people into not buying a particular product.

So tell me, why is it that people are misusing this term? Is it gross incompetence? General lack of knowledge? Me? I don't really know. That's why I'm asking you guys to figure this out.

If you have a mid/low end pc and put in a highend GFX, youre going to have a botteneck, period.

That's not necessarily what I'm going after with this.

Because a low end cpu can 'bottleneck' games or cards? There are tests at techspot which show [insert game here] with the same high end gpu but using several different cpus. While some of the titles are 'cpu bound' because of the type of game it is (think RTS), but others, it's the cpu not being able to feed the gpu in that particular game.

What is the 'proper' use of the term? I see a rant here, but not much else. :)

That's not necessarily what I'm going after with this.
You need to clarify then.. you sure are pointed in this direction!

A thread for this? Its a vague term, I dont use it. Unbalanced or mismatched system would be more appropriate. Like a C2D with a GTX980

That way you can include a 300w PSU with a GTYX980 (mismatched)

But there is no industry standard for the term. What 10%, 50% in performance loss. Every AMD CPU bottlenecks a GTX 1080 at 10% or above

First of all, don't take anything on Youtube seriously and your view on humanity will radically change - for the better.

Second, every system has a bottleneck. There is never a perfect balance. What matters is if you will notice it and whether you can fix it.

As always, devil is in the details. People who look past that, end up with shitty rigs. Their loss :)

So you cant mishandle a term if it has no clear definition.

does there need to be? The term just defines a very high level situation of 'slowing down another part'. You don't need to attach a specific value to it. It's bottlenecking at 10% or 50%. ;)

So it becomes a slang term. Like "I drive a beater" or "I live in a low rent area". Its all subjective. The term doesn't belong in a review that's all

Why not? Just because the term by itself is subjective as to the 'level' it's on doesn't mean it shouldn't be used in a review. At times when the term is used it is backed up by data which defines 'how much of' a bottleneck or where it is. I haven't seen a misuse of the term much... at least not enough times to start a rant thread about it anyway, lol!

The example in the first post is a legitimate question!

"I'm building a PC for gaming, will my 860K bottleneck my 970?"

It is not a misuse of the term. Your definition may need to be expanded as your definition is a bottleneck to your understanding! ;)

In engineering, a bottleneck is a condition where the performance or capacity of an entire system is limited or being restricted by a single component, or small number of components, or a resource.

In a computer, there are many potential bottlenecks that come into and out of play, depending on the specific task at any given moment.

Potential bottlenecks include but are not limited to:

Amount of RAM
Speed of RAM
Bus speed
CPU speed
Number of CPU cores
GPU speed
Amount of graphics RAM
Speed of graphics RAM
Graphics interface I/O bandwidth
Network speed/bandwidth
Internet speed/bandwidth
Disk speed
Disk interface I/O​

The most common thing is a bottlenecked gpu by a slow cpu. Many users use a fx cpu with gtx 1070 for example. Or your own example of a entry class cpu with a mid class gpu.

Also bottlenecking is always present. If your cpu isn't the bottleneck the gpu is. But if you have a fps of over 100 it doesn't matter much.

Okay let me clear this up. It your only utilizing 60% of your CPU and 80% of you GPU there is no bottleneck. If your system is idling there is no bottleneck

LOL just that it never happens usually. Also the bottleneck is the game settings or game then. :p

I've seen this since I've been here. It's common, I don't understand the rant. New people are introduced to PC building/gaming all the time. The first questions people seem to have is with "bottlenecking" and thermal paste.

@Bill_Bright You've nailed it again. :)

Here's a slightly different angle on it, but it means the same thing, ultimately.

To everyone: thing is, whenever a PC is running (or any system for that matter, doesn't have to be a computer) there's always a bottleneck somewhere or it would run infinitely fast, so going on about one is a bit silly. It's the overall performance and where the bottleneck is that matters.

Let's say one has an older PC, especially an AMD one which can only achieve say 80-90fps in some game. Is it dumb to get a really fast graphics card for it and run it at 1080p where it could do 300fps? Not necessarily. All it means is that if you're happy with a solid 60fps, then just turn on vsync and the powerful card will then let you max out the details without it dropping any frames ie going below 60. I had just this situation with my old A3800+ back in 2009 before I upgraded to an E8600 CPU and it worked just fine.

Especially because your cpu is old the 6 cores help lift the limitation or bottleneck. GTA 5 uses the additional cores.

Correct, the limiting factor is my GPU as it runs at 99% to achieve 52 -60 fps with vsync.
