Will my i5-4670K build bottleneck a GTX 1080?

[SanjayP]

Hey LTT community I was thinking about upgrading my Asus Direct CUII GTX 780 that i bought two years ago for either single or SLI GTX 1080's. Will my i5-4670k, Z87 PRO and RM 750 be able to handle them? Any responses would be much appreciated. Thanks.

it will bottleneck. get an e3 1231 v3 or i7 if you can.

How?

[Morgan MLGman]

Yep, any i5 will bottleneck the 1080. Even the 1070 will be bottlenecked with your CPU in some cases, even by 20%.

 

If you're at 1080p, get the GTX 1060 or RX 480, if you're at 1440p, 1070 or 980Ti is where you wanna be.

If you don't have an ultrawide or 4K monitor I see no point to getting a 1080, instead get a 1070 or 980 Ti or Fury X and a 1440p IPS monitor

Fuck no.

[Misanthrope]

This misconception is truly spreading like wildfire.

 

For the most part, no it will not.

 

The only bottleneck present on the 1080 and 1070 is high refresh rate 1080p. As if you want 144hz gaming then it will be a bottleneck.

 

This is the only case confirmed to be a bottleneck and there's basically nothing to worry about on 1440p or beyond since games become GPU bound once more.

 

People if you watch a video on the internet, please watch the entire video and not just read "bottleneck!" and panic. This is not an issue for most.

You will not have a bottleneck. But what are your monitor specs?

Right now i just have a standard 1080p 60Hz IPS but if i do get the 1080 ill probably get a cheap 4k or 1440p

If those are 60hz, you'll be fine. If you're going higher I'd consider adding G-Sync for smoother refreshing. But there won't be any bottlenecks for a good while.

You would be wuch better off with a good monitor and a 1070. Monitors don't get deprecated like GPUs do and a lot o the time they end up lifetime buys.

rofl, no bottleneck with an i5-4670k and a GTX 1080, please do not spread misinformation

I think it's real funny to see this how the 4.5 GHz i5 performs very similarly to the 4.6 GHz i7, sure there's some peaks and valleys, but really here they're performing about the same at near equal clocks, this has a lot to do with the way games use cores which could change with dx12 if devs make stuff right.

But OP you'll run a single 1080 fine with a good overclock, it won't be some fantastically huge bottleneck or anything, technically speaking it will be bottlenecked, but as Linus has said about bottlenecking, "everything has bottlenecks" But the bottleneck will be sufficiently small as to not matter whatsoever

I remember there was a thread where a i7 920 did not bottleneck 2x GTX 970's,that was quite interesting...

I can say the same about you: he asked about the monitor to address the rare case that surprise, surprise: doesn't applies to him since he is not planning on 144hz 1080p gaming.

I informed him that he will not be getting maximum and optimal performance from a 1080 with his CPU, which suprise suprise, is called a bottleneck.

 

Just because FX-6300 is capable of hitting 60FPS with a card like RX 480 at 1080p, would you recommend it to a 480 "because it's enough for 60hz 1080p"?

You based a previous "bottleneck" comment off of a benchmark testing 144hz games.

Games where the GPU AND CPU were both working at >90%. That is NOT a bottleneck. That is called working as intended. If the CPu was 100% and GPU <70% you MAY be dealing with a bottleneck.

I didn't know i5s would bottleneck for gaming... very interesting, thanks guys

Except he will get optimal performance out of 1440p or 4k which is what he wants. Almost nobody wants 1080p 144hz the only confirmed bottleneck. So confirm a general bottleneck on 1440p or 4k with testing please.

Read my post above. I'm not saying this combo will not work, I'm saying that he will not be getting all out of his GPU because his CPU will be the limiting factor sooner or later.

I play triple monitor 1080@60 (5760x1080 in case you need the resolution) and I experience ZERO issues.

Except that is not true at all: newer games will become more graphically intensive rendering them back to being GPU bound or balanced at worst. There is nothing to suggest games will suddenly be CPU intensive and there is nothing to indicate that hyperthreading will be a huge factor.

 

You're basically talking hypothetical about what future games might do and want to assert that as fact, you're just guessing. The only certain bottleneck is the one I mentioned.

One of the users two days ago posted a DSR'd 1440p The Witcher 3 in which an i5-4690k @ 4,5gHz is capped at 100% across all cores and is bottlenecking his OC'd GTX 1070.

Just because your usage doesn't give issues doesn't mean they don't exist. @App4that had an i5 paired with high-end GPU and needed to switch to an i7 because it was bottlenecking.

 

Not to mention frametime drops that occur on i5's and not on i7's. + Games that get higher FPS with an i7 either due to hyperthreading or to more cache. Only an i7 will give you an optimal experience with the smallest amount of bottlenecking.
