1070 Bottlenecked by 6600k?

[FatPenguin]

So I have heard that if I get a 1070 to go with my 6600k it will be bottle necked. is that true?

[HKZeroFive]

For 1080p 144Hz, yes. Otherwise, it'll be fine at 1440p and above.

only is very cpu intensive games

Source on that? My gut feeling is that it would not be a bottleneck even for 144Hz. Maybe in very CPU demanding games, but not in general.

I have a 1080p 60hz monitor is that gonna work or no?

Yes it will, @don_svetlio

yea, for sure

This'll be probably total overkill, but yes it will work just fine

hahaha what a troll

Nah.  Your IPC is relatively similar to a 6700k.  Pretty hard to bottleneck unless the game is optimized like crap.

Here's my thread with @legacy99's results in Witcher 3 with his i5 4690K:

It'll be fine. It's only a concern for 1080p 144Hz.

I imagine any cpu will have some trouble on 144hz in some cases if the game isn't really made for it (feel free to correct me).  My understanding is that those refresh rates should be reserved for more competative games.

I rate that thread as inconclusive, because it did not actually test if a a faster CPU would give more FPS (and only 1-2 games). You can't just say "well I get 100 FPS and my CPU is at 90% usage, so therefore it must be a CPU bottleneck!".

The "##% CPU/GPU utilization" measurements aren't that reliable either, because not all parts of the GPU are fit to do all types of work. If a certain part of the GPU is 100% taxed then it might still only show up at 30% GPU usage, because the rest of the GPU is sitting there waiting for the part that can't keep up.

 

In order to prove that it is a bottleneck you have to test with a better CPU.

 

 

For example here is a test in DOOM which shows that not even a Phenom II x4 at 3.2GHz will bottleneck a GTX 1060 in general (the RX 480 however, gets heavily bottlenecked like crazy).

I doubt that games are made with that sort of mindset. I'd like to think of it that all games are made for 144Hz gaming, it's just a matter of how hard or how easy it is to achieve 144FPS and above.

 

The higher the FPS, the more load will be placed on the CPU. The higher the resolution, the more load will be placed on the GPU. At 1080p 144Hz, it's in your best interest to go for a i7 with such a powerful GPU.

Feel free to ask @legacy99 himself. The whole i5 4690K bottlenecking the GTX 1070 debacle is the reason why he got an i7 6700K.

At 1080p it's a bottleneck. AT 1440p no.

Games benefit not only from i7's hyperthreading, but also from bigger L3 Cache, all of that helps greatly with frametimes which eliminates stuttering and improves overall gaming experience. Not to mention higher framerates on average.

How exactly is it a bottleneck at a lower resolution?

At lower resolutions, CPU has to work harder, as the bottleneck is not with GPU and it's able to push higher framerates. The CPU can push only so many framerates, if the GPU is able to push more, it's being bottlenecked. At a higher resolution the GPU is able to push less, therefore the CPU does not bottleneck. Couldn't put it simpler I believe.

I think the reason he was confused was because don only mentioned resolution and not refresh rate.  At that point a cpu bottleneck won't matter though.

 

What I would take away from all of this is that if you're somebody with the sense to buy a 144hz monitor, you should have some top end CPU/GPU power to go with it.  This is an extreme case though, I wouldn't expect every game to run at 144 fps even with an i7.  That being said, if you have the budget for a 144hz monitor, you probably have the budget for an i7.

 

For the OP though, I'd say get the i5, but maybe also consider the 1060/480 instead of the 1070 if you want to save money.  More people would consider the 1070 the sweet spot for 1440p.

This.

 

But honestly, Who Cares???

Even if you can have 140 fps instead 130 fps with an i7. Is this worth the Upgrade for YOU?

 

You need to ask yourself one Thing: The fps your CPU + GPU combination delivers you in your prefered settings. Are those fps enough for you? If yes, everything is fine. Np.

 

I mean.. As a Gamer you have ALWAYS a Bottleneck. There can Not be a situation, where you don't have a Bottleneck. If your CPU doesnt Bottleneck, your GPU will.

2160p on Maxed out details on dual Titan XP. Even then, the both Titans will Bottleneck. But who cares? You have those Hardware, and they can deliver xx fps to you. The Question is, of these fps are enough for you, or not.

 

You have the latest Technology with the i5 6600k. Only thing that's missing is Hyperthreading. that's not a big deal. And no reason to upgrade. OC a bit maybe, and you're more than fine.

You need to also consider the fact, that if you get a 1070 and a weak CPU, you'd realistically get the same performance as with the 1060. Additionally within the same budget you'd fit the 1060 and an i7 for example, so you won't be forced to upgrade your entire rig next time you need more performance, but instead you can just swap out the GPU.

[Darkseth]

No.

The i5 6600k just misses Hyperthreading. That isn't doing such a HUGE impact, that it loses 40% performance (even if Hyperthreading would scale 100%, it would barely scratch the +40% theiretical performance in synthetic benchmarks^^).

 

Even if the CPU bottlenecks a LITTLE BIT (it will NOT be more than that. We are still talking about an overclocked Skylake!), the 1070 will always be faster than the 1060.

You would have to pair it with an non-OC 6+  Year CPU, to have literaly no performance difference between 1060 and 1070.

 

You need to consider how MUCH it bottlenecks. It's not that it either doesn't bottleneck, or if it does, it jumps directly to -50% performance loss. It can be 0% bottleneck (in GPU intense games, like star wars battlefront), or 10%, or 15%. or 6,79%. ^^

That video only shows a partial CPU bottleneck, in one game, in a specific area. A single area in a single games is not enough to definitively say that a 1070 gets bottlenecked by a 6600K in general.

Again, still haven't seen any actual evidence that supports the very broad statement that a 6600K will bottleneck a 1070.

I have so far seen one particular area in a single game showing a difference. That's it. One area in one game. In order to make a broad statement like "it does bottleneck a 1070", you need to have ten, 15 or 20 games tested. You can't make a generalization based on one or two games. So unless someone links me to a trusted reviewer sitting down with a test bench and tests a double digit amount of games, and only changing the CPU from a 6600K to a higher performing one, all these generalizations will be just that. Assumptions based on a insufficient evidence.

[Darkseth]

Not in general. On CPU-intense Games.

Witcher 3 is known to be quite CPU intense.

 

Most Games are still GPU-Bound, and the CPU doesnt Matter almost at all.^^

 

You can absolutely NOT make a general statement just because of ONE single Game.

Just like you can Not make any statement about Vulkan, if there's only One single game out.

 

And still: Just watch your own Video there in Witcher 3. Watch the i5 fps.

Are those fps enough for you? Yes? no problem.

No? Then you might wanna switch to an i7 (which runs on lower usage%, but still doesnt provide that much more fps).

I mean... Is Witcher 3 unplayable with an i5? Does it stutter? 

What i can see is, the fps are constantly above 60 fps --> smooth, since most people have a 60 Hz monitor, and should use VSync anyway^^

 

Since the Thread Operator did not mentioned, if he has a 60 Hz Monitor (i5 vs i7 is completely irrelevant), or a 144 Hz Monitor (i5 might bottleneck a bit more than an i7).
