i5 bottlenecking GTX 1080?

[zoog18]

Will my i5 4670k at 4.0ghz and also at stock clocks bottleneck the new GTX 1080, will the 1080 be able to achieve its full potential with the i5?

 

[Robert Cook]

at 1080p? it might be held back a bit, at 1440p? very unlikely, and 4K? not at all.

 

[Robert Cook]

it is a K chip so you can always OC it if your motherboard is okay.

 

[dangus]

it will be fine.

 

[dangus]

it's still a quite top-of-the-line CPU

 

[innocent bystander]

It could probably drive 2 of them in SLI, so most likely your 1080 will bottleneck your i5.

But then again, all this discussion about bottlenecks is getting a little old. You will never build a system that has no bottlenecks. Your GPU will bottleneck your CPU, or the other way around, or (if you magically match the two perfectly) your RAM will be a culprit and if all else fails, your hard drive or SSD will bottleneck the rest of the system.

Does it really matter if you are losing a few percent of utilization here and there?

Not to mention that different games use your resources in different ways so your bottlenecks will shift depending on what you are doing.

In short, don't sweat it. It'll work great.

Only if you game at 1080p on an 144hz monitor, and only in some games. But not in a manner that will influence your enjoyment.

For the most part, though you will get some CPU bottlenecking at any resolution in some scenarios, even 4K.

Long story short is that any CPU bottleneck will be relatively insignificant. Put another way, a better CPU in those bottlenecked scenarios is unlikely to produce an observable difference though in testing it would be noticeable.

*So ENJOY*

Also this card was never intended for 1080p, for that I would get a 1070.

Just an example. Almost worst-case as Fallout 4 uses old code that is horribly inefficient with the CPU especially.

As you can see, even the i5-4690K isn't at the top of the charts for 1440p (Turbo would be 3.9GHz).

It's just an EXAMPLE, and again atypical.

(it doesn't affect the point, but F4 needs a 60FPS cap to run properly, and since you rarely drop below that your real-world experience is about the same as the best CPU)

Starcraft 2 is another example where you'd get CPU bottlenecking. When battles get intense you get limited by all the battle calculations (the engine can only use TWO THREADS so it's also an atypical scenario and possibly the worst-case).

Robert Cook,
There are scenarios where the GTX1080 would benefit even at only 1920x1080.

(not to mention people may update their monitor later, or may have 1080p monitors with higher than 60Hz refresh rates).

Having said that, the GTX1070 benchmarks so far indicate around 81% average of the GTX1080. If we use MSRP that's 81% the performance for 63% of the price.

(If you have a weaker CPU than the Intel used to test such as i7-6700K or similar then the advantage of the GTX1080 shrinks even further in cases of CPU bottleneck)

The GTX1070 is a pretty awesome card for the top-end in terms of relative value.

true I suppose multi monitor or CSGO playing. I should not have generalized as much.

Im getting the idea that the 1080 is way overkil for 1080p, so Im leaning towards the 1070, does it still get solid performance when supersampling, and by how much does the 1070 out perform the 980?

well many benchmarks show it trading blows with a 980ti, so I would say significantly so. the 970 was not much worse than the 980, and the 1070 beats that card all day.

From what I understand, there is no way you're bottlenecking.

Considering your i5 is basically an i7 without hyperthreading, I can't see any way for you to bottleneck.

Supersampling is incredibly demanding, but it really depends on how much you apply. Even a GTX1080 won't be enough in many games if you crank up supersampling too high.

I would however, suggest more typical anti-aliasing methods (MSAA, or newer TXAA, possibly SS for older, or less demanding games if the visual benefit to performance hit justifies it). There's an optimal balance of all settings, and supersampling isn't usually the best choice.

GTX1070 is 81% the perf of a GTX1080
GTX1070 is approximately 2/3rds the cost of a GTX1080
GTX1070 is about 30% better than a GTX980.

It really depends on the game, you might notice a bit of stuttering in some games where say an i7 wouldn't really have this issue but when it comes to average FPS based on the benchmarks out there along with games just not really needing the extra CPU power in general at this moment you should be fine besides the rare title that requires a very beefy CPU.
