This is a Bottleneck.

[Crusader93]

A bottleneck is simply one component holding another component back, because it lacks the power or speed to keep up.

 

A GPU is supposed to work at 99% at all times to pump out all the frames it possibly can(without some exceptions, as csgo and league of legends type of games that is not very demanding. With high end graphics cards, you will usually see around 30% performance, when you have 300-500fps :P)

 

In graphic heavy games, such as Witcher 3, the GPU is supposed to work at 99% at all times. If it doesnt, there is something holding it back, witch(you see what i did there?) in 99% of the cases is the CPU.

The CPU is like: "Hey, there is a wild pikachu here, i gotta catch it before it runs away".

GPU: "Let the fckin Pikachu go, i need your help up here!"

CPU: "Fck you man, ima gonna catch this pikachu!"

GPU: "SEND ME THE FCKIN FRAMES!"

CPU: "I will be a pokemon master!"

GPU: ".............."

 

The GPU then needs to wait for the CPU to catch up, redusing the frames its able to give, because the CPU does not render them fast enough and sending them to the GPU. This is usually shown with the GPU's performance % going down, along with the CPU's Performance % going up.

The most alarming is when you see your CPU at 100% load, while the GPU is below 90%. Then you have a serious pokemon trainer CPU that wants to catch pokemon instead of giving your GPU frames fast enough. This results in reduced frames per second, and in some cases the CPU will introduce stutter when pushed to its limits, because it needs more power, but doesnt have any left.

 

Todays CPU's are running short on many newer titles, because more and more games now rely much on the CPU aswell as the GPU.

Every CPU below the Skylake line(i5 6600K, i7 6700K and so on are skylake CPU's) will bottleneck a 1070 and above in 1080P@144hz. When moving up in resolution, the GPU must work alot harder, redusing bottlenecking caused by the CPU(because of the harder load on the GPU). Since it is alot harder for the GPU, it also means your maximum framerates will be heavily redused compared to 1080P. That is why most people(including myself) still play in 1080P. You get alot more frames, but you need a CPU to power it. 

All AMD CPU's bottleneck modern graphics cards, and gets rekt by intel in single core performance. This means the intel CPU's(even if they too bottlenecks) give higher, more stable and higher minimum fps than any AMD CPU to date. 

 

Do not, i repeat, do not believe the myth that old CPU's like a i7 2600k, 3770k or 4770k doesnt bottleneck the 1070 and the 1080 in 1080P@144hz. Simply because, they do. Even the i7 6700K is starting to struggle in that resolution in CPU heavy games. And, the i5 6600K will also bottleneck more than its big brother i7 6700K. So dont believe the myth that the i5 is just as good as the i7 right now either

 

Last, dont think that a slight bottleneck means horrible performance. In many cases, a slight bottleneck only means 10-20 frames lost. And if you dont experience stutter, thats no reason for an emergency CPU upgrade.

If you are sitting on anything less than the skylake CPU's, you will get some bottlenecking with a 1070/1080. But a 1060 will work fine with a 4770K, for example.

Do take note, that some games have larger load on CPU than GPU, such as GTA:V.

Someone told me that GPU can bottleneck CPU. Is that true because i don't believe it,

How is this even a myth? The i5 6600k is a non-HT processor, whereas the i7 6700k is.

It is a bottleneck but the one that doesnt change the performance anyway. GPU is already at its best and CPU cant push it further.  So u already reached the maximum performance of your PC.

[Crusader93]

Actually, that is true. A i7 6700K will get bottlenecked by a gtx 1060 for example. The CPU have the power to send more frames, like a 1080 would need. But the 1060 are already working its ass off producing all the frames it can.

Since the CPU has more power to give, it gets "bottlenecked" by the GPU. But not in the same way! A GPU working at 99% is a good thing, because you get all the frames it can produce, while the CPU only works as much as it has to power the GPU.

 

Point being, GPU bottlenecking a CPU is only positive, because you get all the frames the GPU can produce. A CPU bottlenecking a GPU, results in much lower frames, which is bad.

I have seen alot of people stating that the i5 6600K doesnt bottleneck, and is just as good as the i7 6700K for gaming. I just wanted to state that so there is no confusion with that. We dont want people hurting themselves in confusion, do we?

I'm glad you clarified 1080p 144hz since the new cards should really be encouraging people to move to 1440p already. I know it's expensive (still on the fence myself cause of price) but another interesting option is DSR to basically render at 1440p and then downscale.

 

Doesn't looks as good as native resolution but it works a lot better than even the fanciest AA techniques out there.

Thanks!

I have had almopst all the G-sync 1440P monitors on the market, and i have to say that 1440P on a 27inch monitor is not that much greater than 1080P on a 24inch monitor. It takes alot less power(meaning you can power it much longer before having to change GPU). therefore im sticking to 1080P alot longer

The whole point of this thread, was to help people understand what it is. That way, people dont have to wonder, and make 40quadrillion tons of posts about "are my system bottlenecking?" or "what is a bottleneck?"

Actually I am looking at 24 inch 1440p pannels. They're cheaper in price and do offer a bit of a bump in DPI (1080p 24 inch is almost the same DPI as 1440p 27 inch btw)

 

But a 1440p 24" gysnc panel? Flat out haven't seen one.

Yea, but well all that i5 vs Pascal 1080 talk, u know. Some people think they will get like 10fps or something everytime they hear word "bottleneck".

I wont recommend 1440P on a 24inch monitor. It will be hard to tell the difference between it and 1080P. But the GPU usage level will be heavily increased because of a difference you hardly notice. Not worth in my opinion

Almost all sites explains it, but nevers actually shows how to eliminate it or try to reduce it to a minimum

Found a video on, how to do just that.

 

@Thony

Sucks to be them. Spend their money and they're worry about some number at the top left of right corner of their screen. Why own a computer then?

[Crusader93]

There is info about everything on the internet. How understandable it is to everyone, varies quite alot. Why go to math classes and have teachers if you can just learn all by yourself on the internet?

[knightslugger]

i say if you don't want to bottle neck, don't game so hard...

Because people have the tendency to laugh in your face and doubt you if you tell them you learned something on the internet. Because screenshots apparently don't qualify as credentials, your awesome K/D goes unappreciated by potential employers, and your bank refuses to accept GTA $ as a valid currency.

My point was that sometimes you need someone to explain it to you to understand it. Many times its hard to understand. According to all the post we have seen on this topic, there has to be some truth to it. There are also many myths and false information about PC hardware on the run, and that's important to get rid of.

It'd be more efficient for a few people to come together and put together a combined resource than to try to out-convince the millions of people spreading misinformation.
