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

[Mira Yurizaki]

Urgh, so much misinformation everywhere!

 

Bottlenecking is not a system wide thing, it depends on what you're doing. Just because one game has a bottlenecking condition, doesn't mean the entire system will! That's like saying a drag race car is better car no questions asked than a Nissan GTR simply because it can beat the GTR in a drag race, neverminding that the GTR will kill said drag car if a turn is involved.

 

Profile what your system looks like during the games you run. That video claims an i5-4690K will bottleneck a GTX 1070 in Crysis 3? Huh, I ran Crysis 3 and managed to cap my GTX 980 with a CPU load of 65% on average using a i5-4670K.

 

Please note that unless your CPU is consistently high, you do not have a bottleneck.

Not really: room temp for me is sadly almost 30c 

 

And yes Novigrad sees dips into mid to high 50s but only for a few moments at worst.

so i've tried it myself..

Not sure if highlight was a grim joke or not.

 

And agreed.

Is this a too soon hyperbole?

You can see in Novigrad there's a few seconds on the entrance and near the main square where you get to 100% utilization but it's mostly not being really hammered and consistently at 60 FPS without stuttering.

Have you experienced a bottleneck? The GPU doesn't matter, you could have Titan X SLI and you're still getting hammered by fps dips that break immersion.

I'm thinking about doing a comparison video with my i5 4440 at a 104-105MHz BCLK, and then my 4790K limited to the same maximum frequency. I already know that my GTX 970 G1 Gaming at 1429MHz was bottlenecked in newer games, while with my 4790K its never bottlenecked.

 

For everyone else BTW, my Xeon X5450 @ 4.4GHz got the same maximum and average frame rates as when I used my i5 4440 and 4790K, and that doesn't mean that I shouldn't have paid attention to the GPU usage not being 100%, the low minimums and poor frame times.

Since i was brought into this thread and coversation. ...sorry out in vacation and typing this on my phone...but i am personally upgrading from my i5 4690k to the i7 6700k due to this issue i have personally tested and experienced with cpu usage at 100%. During this, i never personally felt any type of stutter, micro or otherwise. I am upgrading only because i do not personally like a game maxxing out my cpu usage that can cause the stutter from dropped frames as a result. For 99% of games an i5 is without question fine and sufficient. We will need to see how heavy ai type games such as TW3 react if they push a d12 update to it. Only time will tell, but this is likely the beginning of the end of the i5 mainstream gaming era in my honest..and humbled..opinion.

If you're playing at 1080p yes, if you're playing at 4K no. Depends on the game as well.

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. 

Your monitor is going to be the bottleneck on that gpu. It's going to be an enormous bottleneck.

Yes. But it's hugely dependent on the game. League of Legends, for example, will be hugely bottlenecked by your cpu, but it doesn't matter because you get more than playable framerates. Grand Theft Auto, on the other hand, will be bottlenecked so hard by your cpu, that it's almost unplayable (if you are sensitive to low framerates like me). Who can you blame? Intel for refusing to give us big performance gains from generation to generation, and AMD for making garbage.

AMD for not holding their end of the bargain.

GPU not being at 100% while the CPU is does not indicate a bottleneck. If the GPU is rendering every frame that it can it simply will not do more work. GTA V has a LOT of AI and your CPU is dedicating all of it's power to it as reserved.

[TheKDub]

Your i5 4670K will be perfectly fine.

lmao. Bottleneck is one of the most misused and misunderstood terms in the PC hobby. Terms that need to go:

Bottleneck

Investment (a PC isnt an investment)

Budget (well this one just needs to be used correctly as in listing the budget. Stop using it to describe low cost items)

 

Sorry for the rant

A PC is an investment if its critical for your job.

Bottleneck, quite an apt description for what happens with the correct (or wrong) combination of hardware:
 

Quote

bottleneck

ˈbɒt(ə)lnɛk/

noun

 

1. 1.

   the neck or mouth of a bottle.
2. 2.

   a narrow section of road or a junction that impedes traffic flow.

   "the bottleneck on Talbot Road"

   synonyms:

   traffic jam, jam, congestion, hold-up, gridlock, queue, tailback;  constriction,narrowing, restriction, obstruction, block, blockage, stoppage;  informalsnarl-up "cars were advised to avoid the bottleneck on Talbot Road"

I said misused and misunderstood terms. Bottleneck gets thrown out there way to often and is misused way too often by people that do not fully understand whats going on. And how many people on this or other forums use their PC for work? Again, investment is often misused. Most people on forums are PC hobbyist. Saying a PC is an investment is misuse of the word, most of the time. None of the electronics I have will ever get me more money then I spent on them. And this is true for most people. PC's and other electronics are not an investment, most of the time.

Can I ask what you used to record your video, and which settings? Because I have a 1070, and I tried recording AC Syndicate, and FPS dropped by about 20 - 25 using Afterburner's video capture.
 

Btw, this is my Witcher 3 Novigrad performance on my i5 2500K @ 4.6 Ghz, with GTX 1070 SC (2113 clock / 4581 mem):

 

 

 

 

Regarding the subject of bottlenecking... I think that a bottleneck means something when it degrades performance tangibly. If an i5 might be bottlenecking by 5%, in 5% of gaming situations, I don't consider that to be significant to the decision of whether to buy a certain graphics card or not. And I think calling something bottlenecking when it isn't even impacting that much of gaming is kind of inane, because it isn't accurately communicating what the value of any performance decrease is.

 

For example, if a person chooses to buy a 1060 instead of a 1070 because they're told the 1070 bottlenecks their i5, when it might not even be a 3% bottleneck across their whole gaming experience... then I think that person would have been misled, and made a purchase decision based upon incomplete information. Maybe when a bottleneck is present in 40%+ of games played, and is by 10%+ performance in those 40% of games played, then that would be notable performance that was paid for and isn't being accessed. But it looks like most decent i5s, including my i5 2500K @ 4.6 Ghz, aren't experiencing any tangible kind of bottleneck with a GTX 1070 (other than in Arma 3, lol).

 

Also, my particular GTX 1070 is overclocked a lot, getting around 10.5% added FPS performance over its default EVGA Superclocked configuration, and if it were a stock 1070 (though, with GPU boost, is there really such thing as a stock 1070?), there would be more safe distance before I started losing GPU performance.

 

It looks like i5s are really starting to meet their limits in some things with high performance GPUs, but that they're generally still competent for high performance GPUs. Maybe the true line-crossing will be with the Titan X and 1080ti.

If you're using Nvidia, Shadowplay is great.

I'll try it out. I hope it has little impact on FPS.

Bottlenecking isn't a black and white thing. Bottlenecking all depends on the game and graphical settings and if you graphical and performance goals are met then its pointless. Even a i7 6950X is capable of bottlenecking a GTX 1080 depending on the game.

that thread is FULL of bullshit...the i5-4670K EVEN AT STOCK is PLENTY for even a GTX 1080 at 1440p...of course if you're trying to lock a 144FPS at 1080p on that it ain't happening (and it's not happening on the i7 EITHER)

 

^^ we can see from that post that this guy has his GPU PINNED at 99% usage across the board in the most demanding portion of the witcher 3...so this is a WORST CASE SCENARIO and even then he is using a 4 generation old i5-2500K and the GPU is PINNED across the board which put this to rest...NO the modern core i5 haswell chip WILL NOT limit your gaming experience in any way shape or form... @SanjayP your CPU is fine...just get yourself the GTX 1080 and a 4K or 1440p monitor and you'll be amazed by what it can do in games.
