What GPU maxes out the PCI-e 2 slot?

[Sin Stalker]

I have an x58a mobo with an i7-930. I currently have a GTX 660 inside. I want to upgrade my GPU but I know that my PCIe slot is previous gen and will be a point of bottlenecking. With that in mind, what GPU is the maximum GPU I should be going for, for this build? At a certain point, I'll have a gpu with abilities that are not being utilized and want to avoid spending money for power I can't use.

What answers did you get? Can you link to it?

Basically even a GTX 1080 won't start showing signs of appreciable performance degradation until you go down to PCIe 1.x x8 speeds, depending on the resolution.

You are so helpful today

Worked fine for me.

 

TL;DR also is that pretty much no GPU out there today is really all that held back by PCIe 2.0 x16

[Sin Stalker]

None of this is actually answering the question. I see alot of "barely or not at all", with zero definitive answers, which makes me think people don't know what they are talking about.

 

For instance, if a 1080 is barely bottlenecked, is everything below a 1080 not bottlenecked? Or So a 1070 isn't bottlenecked at all?

 

Back to my question:

I'm looking for what the highest performance card is that wont experience any bottlenecking.

Not true, just particularly helpful today in the sense that I've seen them answer the same question twice now

In any case, no it will not bottleneck. Even if it does you won't notice it

I don't think you get it. If it does bottle neck, then it means I spent more money than I have too.

This isn't about "will I notice it bottle neck". This is "what is the most powerful card available that won't bottleneck, cause I don't want to spend money on power I won't get to use".

It.

Will.

Not. 

Bottleneck.

No card will.

Period.

And I am saying the difference would only be one or two fps anyway which equates to what $0.50 maybe? Your question is difficult to answer because there isn't an easy way to look at it. The links Yurizaki posted on the other thread explain the differences between performance on different kinds of slots if you want real data but it will be hard to find out exactly which gpu will be exactly within the limits of your board

It isn't like, this is the pcie 2.0 bandwidth and this is a list of GPU's push?

The links talk about the effect of different bandwidths' effect on performance doing different tasks. The bandwidth is based on the kind of PCI-E slot they use which is exactly within what you asked

pci-e 2x16 will take off at most 1% of a gpus potential performance if that, you're best off trying to match a gpu to your cpu as it may actually have an impact

According the links provided, its way more than 1%.

So it definitely shows a bottleneck occuring, from the first link. I wish the same test would be run with previous gen cards to find where bottlenecking isn't occuring.

Not according to the data.

I guess that depends on what you mean by held back. But there is bottlenecking occuring based on the links provided.

The links you provided still showed bottlenecking occuring. Do you have anything that goes back previous generations to find where the bottleneck halts?

I don't unfortunately but there might be more info on those websites. If they did tests like that they may have older versions from when the older generations were more popular

As far as this goes this is what I was saying, there is no easy answer hahaha

Yeah, I see that. Depending on what type of data the GPU is crunching will depend on the bandwidth required. 

 

This should be something the LTT crew tests.  How do I submit suggestions?

I mean, technically yes, there is a bottleneck happening. However in my response I added the qualifier appreciable. Meaning unless you spend the time scrutinizing the performance while in game, you're not going to notice it. And unless you're running top of the line hardware, you are always going to bottleneck somewhere.

 

If you're going to worry about losing 10 FPS when you're already achieving 120+, then I don't know what to tell you.
