"Bottlenecking"

[corrado33]

Can we please have a "how bad does your CPU have to be to actually bottleneck various GPUs" video? 

 

"Bottleneck" seems to be the word of the month here. Everyone worrying about bottlenecking.

 

As far as I understand it, you need to have a pretty slow CPU to bottleneck modern GPUs as MOST games are GPU intensive. Some are more CPU intensive, but that's programming not hardware. And if you're not running super high end setups, you're not likely to run into any bottlenecks. 

 

Almost every game I've played my CPU sits around 30-40% usage while my GPU can be pegged at 100%. This is with a 1060 6GB.

CPU dopesn't have to be at 100% to be a bottleneck.

what CPU are you using though? this lack of detail is bottlenecking your post/question

Gracias señor. Although I'd like to see a more indepth video more along the lines of "With a 1080 Ti" you'd need a "insert crappy CPU here" to bottleneck it in this CPU intensive game.

OP needs to google/youtube more proficiently, its bottlenecking him

There are various articles on the topic, but one of the main issues is you really need to test a lot of configurations to get a good amount of data.

 

Tom's Hardware recently posted a really nice article on this sort of: http://www.tomshardware.com/reviews/multi-core-cpu-scaling-directx-11,4768.html

Tech Spot also does game benchmarks with various CPUs: http://www.techspot.com/features/gaming/gaming-benchmarks/

And this ol' article from PC Gamer: http://www.pcgamer.com/will-your-cpu-bottleneck-your-graphics-card/2/

 

I think the problem is fear and a numbers game. I believe people fall into one of two camps, if not both of them:

• They want to get 100% performance out of their part. Even getting 95% is somehow the end of the world for them
• If they are not getting 100% performance out of their part, then that means that's all the performance they'll get, period.

It doesn't matter what the CPU is. If it's being taxed to the point where it can't send rendering commands to the GPU faster than the GPU can render the frame, it's bottlenecking the GPU.

"but that's programming not hardware." You still have to overcompensate that with hardware if you want to play it. You can't just re-code it, meanwhile you can make sure to have a proper CPU for it.

And yeah, people are asking if their CPU is going to be a bottleneck when it's not going to. But that's simply because they do not know, for that reason we(this forum member) are here to help

It's not for me. I know what I need and don't need. It's for the millions of threads we get on the subject.

 

Although I didn't realize Linus directed people here to sort out those problems.

 

Ugh, guess we'll have to deal with "Will my if 6600k bottleneck my 1080 something or other" for a while longer...

 

Heck, at this point I kinda just want to make a master thread with people with known CPU/GPU combos and whether or not they are good.

Thanks for the links. But this sentence is exactly why I think LTT should do an in depth video on it. They HAVE all of the configurations. At least do it with new cards. What's the cheapest CPU you can get away with with this card to not bottleneck it.

 

I think it'd be very useful.

im with you.

this forum has been on repeat for years

They are clueless. Heck, they do CPU benchmarks in GPU-bound situations...

*SIGH*

 

Unless you plan on always running everything at Ultra settings at the highest resolution, one could remove a bottle neck (either perceived or real) by just throttling down the settings so that one bottle neck overlaps the other.

 

if you're gaming at 1080p and you get 60 FPS... and that's as fast as your monitor can go... ask yourself: what's the REAL bottle neck here...?

[Mira Yurizaki]

Ultimately the problem though is nobody will bother to read/watch/etc. any information before posting on the forum "WILL THIS BOTTLENECK MY UPGRADE!?!?!!1oneoneone"

 

I have a guide as well, but nobody seems to care. People would rather be lazy and have someone say "yes" or "no". I think we should just default to "yes" to be facetious :3

I like it.

I shall quote myself from another thread, about the same topic

A lost in performance not from the actual hardware itself, but from that person's imagination.

Gots a GTX 1080, went out and spend another $1700 on a 6950X. "Still bottlenecks"

Sheeeeeittt!!!
