6700k 4.5Ghz vs 5820K 4.5ghz

Caracus2k · 6 Mar 2016 at 23:00

Just looked at the opening post again its not even a valid comparison from what's apparent from the photos....

6700k

4010Mhz memory 1501Mhz core

5820K

3506Mhz memory 1329Mhz core (click on image and zoom in for clearer picture)

I'm assuming both scenarios are GTX 980's?

What exactly are you supposed to glean re CPU performance when the GPU's are set up so differently? Am I to take the op at their word that OS/ system memory etc was consistent across both systems

gee wizz an overclocked 980 on a 6700k (apparently) beats a more conservatively clocked 980 on a 5820K (apparently)...

6700k have GTX970 5820k have 980TI

so it makes absolutely no sense to compare them re their respective CPU performance then?

lumik · 6 Mar 2016 at 23:19

ALL test are CPU limited.You can see GTX980TI runs at 60% usage and GTX970 at 89% usage.

Do you know how CPU bottleneck scenes works?Its dont matter if you have GTX960 or TITANX.You will have same fps.

Well this information is kind of key don't you think?

Why if all scenes are cpu limited?You see 5820k have 980Ti and still loses because all tests are about CPU and are CPU bottleneck.

You can even have GTX950 with 6700k and still have better FPs in certain games that are CPU bottleneck than someone with TITANX SLI with slow cpu you know

Because ALL tests, no matter what you're doing, need to be equal to be reliable.

Such a waste of a thread.

lumik · 7 Mar 2016 at 00:51

waste because 5820k have much more powerfull card and still loses because all test are cpu bottleneck.
You guys need learn how pc works.You have no clue.Yeah such waste on my time.
Those test are 100% legit
Believe or not bye.

5820k at 4.5ghz here, very similair in games to my old 4790k at 4.7ghz. Which is equivalent to a 6700k at 4.5ghz. My advise. plough more money into a gpu upgrade if you want a return in games. Anything else aside from gaming that will utilise 6 cores, X99 will win out everytime. With any modern gpu, even a sandybridge i5/i7 will give very playable frame rates, resolution dependent of course.

You should first show that the scene is cpu limited by showing the same result on the same hardware with just the graphic card being changed...

Without a rigorous methodology any comparison is very limited in its usefulness

This

What a waste of time. Regardless of cpu bottleneck, at the end of the day the gpu will influence the results as it's drawing the scene.

lel at people defending their hype purchases after OC tried to shift as much 5820k stock as possible before skylake

Btw all reviews on net sucks except few polish and hardware.fr(and digitalfoundry)..They all test in wrong games or wrong setting or in wrong scenes.They are GPU bottleneck.

So the other reviews on the net use the 'wrong' settings but you expect us to look at a 'Cpu' gaming comparison where not even the same gpu's are used!

If I get the chance tonight ill fire up fallout 4 set my swift to 1080p and test with my graphics cards singly ,in sli and overclocked and we will see how cpu limited it really is!

As opposed to the people defending their overpriced purchases of 6700k's that for a good portion of its lifecycle have been significantly more expensive than a 5820k despite offering very little where it excels (lightly threaded apps and games) and getting totally spanked where the 5820k excels (heavily threaded apps and games)?

Its only been fairly recently that prices have settled down to around £290 ish for the 6700k with reasonable stock levels to match...

ukxenon · 7 Mar 2016 at 13:23

from what i have seen the 5820k is the best bet

Oh, please point me in the direction where I can find these 'heavily threaded games' that everybody is playing???

You say 'lightly threaded' as if it's a bad thing? Hahaha...

I'm sure people encoding youtube videos could really use those extra seconds to go and turn on the kettle or something. Totally a sound investment over tangible FPS in popular games.

Ahaha..did you see that GPU usage?Omg you people have no clue what CPU bottleneck is.
GTX970-89% GPU usage in fallout4 in first scene
GTX970-80% GPU usage in second scene
GTX980TI-60% GPU usage in first scene
GTX980TI-55% GPU usage in second

In both cases game is CPU bottleneck.i am sure people who knows how PC works appreciate this test.Rest just dont post and first learn how PC and CPU bottleneck in games works THX.

setter · 7 Mar 2016 at 14:50

Ideally you should be comparing both cpu's with the same graphics card. A 980ti isn't far off the performance of 970 sli.

tyler_jrb · 7 Mar 2016 at 15:37

The 5820k just IS the better value chip. Extra 2 cores/4 threads for multi-tasking, and the cores DO get used somewhat while gaming. AIT Nice to be able to run a virus scan etc while gaming.

You can also see the 5820k is at 4ghz in this video, the 6700k is at 4.7ghz. 5820k still wins...

At the end of the day, both Skylake and Haswell-E are good gaming CPU's. Of course owners of either are going to defend their purchase, it's perfectly natural to do so. But you'll not get a bad gaming experience with either, both are great.

The majority of the games I play are lightly threaded, where CPU IPC/Frequency has the biggest gains, hence my Skylake purchase.

For those playing the more well threaded games, X99 would be the better choice.

It's that simply really, for gaming at least
