will my i7 4820K Bottleneck GTX 1080Ti ?

[4K Ultra Noob]

Hello, got some question. Gonna upgrade my GPU from 770 to 1080Ti and also getting 1440 Monitor (Asus ROG IPS) .
My Current Mobo and CPU is Gigabyte LGA 2011 with 16gb ram and i7 4820K (liquid cooling) with at base clock 3.7 ghz and it has not yet been Overclock, Now somebody told me (one person) that it is a waste cause it will Bottleneck my rig cause of my Mobo and CPU. is that true? 
Will i have some trouble using 1080Ti? 
Specially my aim is for 1440 resolution on all my games at higher than 60 fps.

At that resolution it shouldnt

[Moress]

No. At 1440p that will be a good setup

[lexidobe]

Nope, that CPU won't bottleneck the GPU. The higher the resolution, the less the CPU matters and the more the GPU matters.

[Jurrunio]

Even if it does at this state I wouldnt hesitate on the 1080ti anyway. Overclocking is always possible if bottleneck occurs.

1. What bottlenecks and how much, depends on your software + settings. This question can NOT be answered in general ;-)

There are games, where you sit in a GPU Bottleneck in 720p. And there are games, where even 1000€ Intel CPUs are bottlenecking in 4k Ultra.

 

But if i had to guess: For most usal games in 2560x1440, and aiming for a 60 fps target, you should be perfectly fine.

 

2. Does your CPU deliver enough fps for you?

Set resolution to 720p, and graphic details on low. Should be enough to let you hit CPU Limit (GPU usage should fall below 100%). Are these fps, you see, enough for you?

If yes, you have your answer.

It doesn't matter if you use a GTX 750, or GTX 1080 ti, or a Quad SLI setup of titan Xp. Your Graphic Card does NOT change the number of fps, your CPU is able to render.

 

3. If your CPU delivers enough fps for YOU, then it doesn't matter if your GPU is not bottlenecked, bottlenecked by 5%, or 20%. You have enough fps.

If your CPU does NOT deliver enough fps for you, then why are you talking about the GPU? ;-) GPU is not interesting in that example, because your CPU alone is the problem. And it won't deliver enough fps, no matter what GPU you use.

[Potato*Salad]

Zero bottleneck at all.

[Princess Luna]

You'll be fine, I had a TITAN XM in SLI with a 3970x which is close to the same CPU and all ran fine.

Just a minor correction: The CPU doesn't render anything. The CPU tells the GPU what to render and the GPU renders the frames.

 

When you have a CPU bottleneck, it's because the GPU is able to render each frame faster than the CPU can provide instructions of what to render. The GPU must then "wait" on the CPU for further instructions. This is why you see GPU load decrease and CPU load increase. 

 

Ideally you want your GPU to always be the bottleneck (run at or near 100%) because that means the CPU is able to keep up and the GPU is rendering as many frames as it possibly can (at those specific settings). The result is typically smoother, more consistent game play (as long as the fps is at or above the refresh rate of the display). With CPU bottlenecking in games, the result is usually choppy, rough gameplay with inconsistent fps and frame times all over the place.

Yea, i meant these CPU-based pre-calculations for the data, the GPU uses for the rendered frame.

I really like most of his videos.. but this one is pretty much garbage....

Where is an i7 7700k?

i5 7600k is there, but nothing with 4 cores + Hyperthreading, to see whats the difference. 

Also, 70% of his video are synthetic benchmarks... lol.

While he's not lying, this Video is pretty much useless.

 

Digital Foundry's Kaby Lake review is FAR superior, to show how much bottleneck you can expect:

 

For example Witcher 3, in Novingrad (most CPU heavy place in the Game).

i5 even at 4.8 Ghz and 3000 Mhz Ram in 1080p / Ultra, is bottlenecking a Titan X pascal (the one from August 2016) quite significantly. It reaches only 105-120 fps, while an i7 can, thanks to Hyperthreading, reach up to 140-150 fps.

 

BUT: If you only use a 60 Hz Monitor, which means, more than 60 fps are worthless (Ideal is a 60 fps lock), this "Bottleneck" isn't an issue. Because it doesn't matter, if your CPU can deliver 110 fps or 140 fps, since you are capping it to 60.

 

 

Still, he's absolutely fine with that CPU

 

Like i said: People should completely go away from that Bottleneck thing ;-)

Either your CPU  / GPU deliver enough fps for you, or they don't.

If they do, everything is fine, no matter what bottlenecks by how much.
