Yes, the OC would be more like 11% from 4.5 to 5 GHZ. But games of course favour the GPU not the CPU so not surprised. In the sim of course which is CPU biased the benefits would be greater.

 

Ah, yes, of course, GPU vs CPU. Still, I think I'd start off without OC'ing and see where that gets me.

After some research I understand Turbo works as follows.

For Kaby Lake something like..

1 core = 4.5

2 cores = 4.5

3 cores = 4.4

4 cores = 4.3

Asus multicore, if set, would then override this and set Turbo under load to all cores 4.5.

Yes you are right, thanks for the link.

The Anandteck article being from 2012 though I would guess there would not be too many serious MBs left today without some form of MCE?

 

gb.

For other modern games OC may not be necessary, but for P3D/FSX one of the core is always saturated so fps goes pretty much linear with CPU clock. Overclocking is a must. Of course, unless you gutted P3D/FSX with way too high graphic-card intensive settings. 

 

To me Kaby Lake has to do > 4.9 GHz pretty much guaranteed. 

Er... I don't think I fully understand. One core is 4.5 and the others are...? Also 4.5 or slower...?

none of the k cpu's push all cores to the max boost clock without doing it yourself. for instance the 6700k has a base clock of 4ghz, 1 core goes to 4.2 ghz and the other 3 stay at 4ghz. the 7700k will run a base clock of 4.2 ghz with 1 core going to 4.5 ghz while the others sit at 4.2. for 6700k owners that can already get a 4.5 ghz overclock, it would simply be a waste of money, nothing can offset the cost from the 6700k to the 7700k unless you are sure you can get 5ghz out of your 7700k and thats probably unlikely

Brett we have been discussing above how many motherboards override this with their multi core enhancement feature.

Certainty with my 6700K, with bios just set to "Load optimum settings", all cores show the same speed simultaneously all the time, up to the 4.2 maximum, again for all cores.

Yep.

 

Worth mentioning that even if we overclock ourselves, we can still simulate Intel's Turbo rules. That's by overclocking "Per Core" rather than "All Cores". 

This from Asus is interesting. And don't forget Asus get hundreds of chips to test long before we see them, in order to design and test their new boards...

Still, Asus' reputation for rock-solid reliability and overclocking performance continues with the Code. It is a high-end motherboard with a high-end price to match, but it (along with several other Asus boards) has a neat party trick: it can push the i7-7700K to 5GHz with a reasonable (read: no extravagant water cooling required) setup. There are a few caveats to that performance—the biggest being that Asus also supplied the i7-7700K for this review, which was likely binned from a large batch—but the company claims that most decent unlocked Core i7 and Core i5 Kaby Lake chips will hit 5GHz between a reasonable 1.29-1.35 volts.

 

 

 

Seems to be, like the guy on the ROG Forum, confirming that if you have an average chip, 5 GHz is feasible. Now Asus are a company I trust. I've not known them to tell fibs or exaggerate... unlike some of the pre-release reviews you are likely to see.

 

It's looking like 4.8 - 5.2 might be the range. Depending on silicone lottery and cooling etc.

Interesting. I was btw already thinking about getting an Asus ROG motherboard, also for the ease of OC'ing. 

Just in...

Essy 4.9 GHz reported with H100i...

 

http://www.trustedreviews.com/intel-core-i7-7700k-review-performance-gaming-and-overclocking-page-2

Again, confirming 5GHz very easy to achieve. Just with an H100i set to silent. This is looking more interesting...

 

 

This is a great review from Tiny Tom Logan on Kaby Lake. Again, confirming 5 GHz is very achievable for most examples. Apparently Kaby Lake was running hot, but then there were BIOS updates and as a result temperatures plummeted!  Seems there were voltage in the background that were the cause so they tweaked them.

 

 

JJ From Asus on Kaby Lake and the new Z270 boards form Asus. Phew, this is getting daft, I'll stop posting videos now. 

:smile:

 

 

the 7700k is out, sadly the performance is tied, if you have a 6700k it's a waste of money.the z270 boards have more usb ports.anyone still using windows 7, you will be forced to install windows 10 if you buy a 7700k. i actually bought a 6700k a week ago and i have no reason to upgrade. wait and pray that amd does bring something to the table.the price for the 6700k and 7700k are both the same as well. anyone on an older platform using windows 10 that plans on upgrading, the 7700k is the obvious choice, they seem to overclock better. it's like going from a 4770k to a 4790k.my thoughts.

Good review of the 7700K at Guru3D: https://www.guru3d.com/articles_pages/core_i7_7700k_processor_review_desktop_kaby_lake,1.html. In the conclusion he says:

 

Very little is different about the 7700K compared to the 6700K. If you clock both at the very same clock frequency, they both will perform roughly similar. As such, the architecture does not make a tremendous step forward in terms of IPC performance seen over Skylake. This does mean that the need to upgrade from any quad-core Intel PC you purchased in the last couple of years really is irrelevant unless you need a platform upgrade (e.g. desire M.2, USB 3.1, etc).

 

With most modern MBs already offering M.2 and USB 3.1, the only real advantage seems to be that you're more likely to hit 5GHz when overclocking. However, if you already have a 4.6-4.8GHz overclock on your Skylake you probably wouldn't even notice the difference. I expected more!

going from 4.6 on a 6700k to maybe 5.0 or 5.1 on a 7700k cant translate to much in p3d/xp11.  waiting for the amd zen , something I havnt said in over decade!!

Can't wait to see how AMD's offering does. Getting slightly bored of Intel dragging their feet with these processors and their artificial limitations, by just putting crappy TIM on the chips if they do too well, so they fit within some pre-arranged improvement percentage. They really need the competition ... We really need the competition.

Overclockers.co.uk have them in stock.  CPU prices not much different to Skylake, but motherboards seem well over the odds
