i7 6700 or i5 6600k for GTX 1070

[FRN]

Hi,

 

I wanna know if the 6600k is a better pair than 6700 for the GTX 1070? I've seen posts that says 6600k will bottleneck the GTX 1070?

[1Reshiram12]

The i5 will most certainly not bottleneck it, in fact it will perform slightly better than the i7 due to the lack of hyper threading. The i5-6600k all the way unless you need the extra i7 cores for video rendering/editing.

For 75hz gaming, the i5 will be plenty. Anything above, like 120hz, will be dependent on how well the game is coded and makes the i7 a better choice..

i7-6700+H110M is actually cheaper than an i5-660k+Z170. Planning to buy a 1440p monitor to go along with it.

The refresh rate is what determines what CPU you should use. Resolution determines the GPU.

Higher resolution doesn't really affect cpu usage.

ps. just found out that the 6600K has lower stock speeds than the 6700 non-K? whoa...

That's almost always been the case. When hyperthreading doesn't help the i7 edge out over the i5, clock speed does.

I knew that was the case for the i7K's, I just thought for some reason that they would make the top tier i5 at least AS fast as the "low-end" i7, just without the extra threads.

That's not something I can truly comment on.

 

The 4690K and 4790 are the ones that pop to mind immediately to me.

i5-4690K is 3.5GHz and the i7-4790 is 3.6Ghz, but the i7-4790K is 4.0GHz.

Where did you get that from?

Benchmarks, personal and published. Some games, like the Witcher 3, will never hit 144hz due to excessive CPU calls. @HKZeroFive can explain more since he usually leaves the Hz-cave when the signal is lit.

I know what refresh rate and frequency and all that stuff is. What I don't understand is how that's directly related to the CPU. Also, what do you mean by CPU calls?

The CPU has to perform "calls" or the portions of the program that it has to deal with itself. If those calls are saturating it's workload beyond what it can handle the GPU will suffer since it relies on the CPU to send the information to be drawn.

*sigh* Hz-cave? Really?

 

Anyway, here's a previous post of mine that explains most of it.

The CPU has two jobs:

 

1. Logics (physics, animations and other such things).

2. Drawcalls

 

Since the topic pertains to the matter of CPUs and GPUs, we'll focus on draw calls. Draw calls are the instructions that the CPU delivers to the GPU on what to render. As I've said before, the lower the resolution, the easier it is for the GPU to render those frames (thus, there's more frames) and the demand for draw calls increases. If we increase the resolution, the reason you're less CPU bound is because the number of draw calls decreases.

 

My argument is that the i5 6600K cannot keep up with the amount of drawcalls at 1080p when paired with a high-end GPU such as the GTX 1070 or GTX 1080. Only i7s or specific Xeons can.

So what you're saying is that i5's cannot handle a 1070 thus a 1060 might be a better GPU for it?

 

Another option is to get an i7-6700+gtx 1070 if thats a better option. It would actually save me a few thousand pesos if I went in that direction due to the price of Z170 boards.

God no. I'm simply saying that unlocked i5s aren't the god-like, 'as good as you can get' CPUs that people conventionally make them out to be. If the budget allows an GTX 1070, go for it as long as the CPU is decent.

 

Plus, you're playing at 1440p, yes? So you're not going to face much bottlenecking... except for maybe one or two games.

 

Personally, I'd choose the i7 6700 but the i5 6600K is an okay choice as well.

What he's saying is if you're going for high-refresh gaming, an i7 (or enthusiast CPU) will be a better choice as it has more wiggle room. If you're going for higher resolution at 60/75hz, an i5 will do fine. The issue isn't the sole pairing of CPU/GPU but those and the monitor itself. Many of us are still using a 1080@X panel and the 1070 and 1080 aren't meant for those resolutions.

Even though it's locked it's the better choice due to the price and performance.

I5's can but not in the same way 2-3 years ago. 2-3 years ago, i5Ks would usually already give you a smooth enjoyable experience where you'll only see some bottlenecking in the 100fps++. 

These days it isn't like that anymore. Because games are getting more cpu heavy. It has been shown(Check out DF's videos) multiple times that i5's have more and severe frame drops than i7.  The 1070 will be a better GPU than the 1060, that doesn't change. 

 

if you aren't getting a 6700K then you could save the money and drop to a H170, B150 or H110 board.

Why does the i5-6600k beat the i7-6700k in tests with all resolutions and high end graphics cards? Is the i5-6600k affecting it in some other way besides FPS? I just don't understand why the i7 would be better if you end up with more frames from the i5 in any situation besides extra threads for rendering and stuff. Does the i5 fall behind at really high refresh rates?

Exactly what tests are we talking about? There are numerous benchmarks that say the opposite.

 

There's countless benchmarks that showcase that an i7 can present its own benefits over the i5. Yet people regurgitate the same old thing of it being unnecessary.

 

Here's just a few to get us started.

 

Gears of War 4

Fallout 4

Battlefield 1

It's been said time and time again that the i7 6700K will provide higher minimum framerates and more consistent frametimes than the i5 6600K... that's the biggest benefit of having an i7. On top of that, the higher the framerate, the harder the CPU has to work which is why the i7 6700K excels in that area because of its extra threads and the i5 6600K doesn't do as well.

 

My favourite game to use as an example is Fallout 4. The difference between i5 and i7 is virtually night and day... no more frequent drops in framerate in the most intensive of areas such as Diamond City. If that's not enough evidence, there are several people experiencing 100% CPU usage in Battlefield with their i5s... hell, even i7s are seeing high CPU usage.

 

Now, let's delve into the question of bottlenecking. At 1080p 144Hz, the i5 6600K will bottleneck a GTX 1070 and above in more than a few games... not so much at 1440p and 4K due to the reason I've explained in my previous post. But then again, the i7 still offers a smoother gaming experience and so for high refresh gaming, you want a i7 to keep those minimum framerates high.
