Overclocking Performance: GPU Tests
In the third page of the review we showed our overclocking results, with our CPU managing to hit 5.1 GHz stable with a sizeable increase in voltage. 5.1 GHz was also high in temperatures, so for our benchmark suite, we dialed back to 5.0 GHz and run a number of our tests again at this fast speed. We also ran some benchmarks at stock frequency but with increased DRAM frequencies. We initially ran the DRAM in our ASRock provided system at DDR4-3466, slightly overclocked beyond its DDR4-3200 sticker value.
For this page (and the next), we’ll show the overclocked results of the Core i7-8086K using the fast memory kits as well as the 5.0 GHz overclocked setting (at base memory). The Core i7-8700K numbers are also included for reference.
Civilization 6
Shadow of Mordor
Rise of the Tomb Raider
Grand Theft Auto V
There's not much to say with our GPU testing since we ended up being GPU-bound most of the time against the Radeon RX 580. In a more CPU-limited scenario overclocking should help, but these aren't it. Though at some point I'd like to dig into Civilization 6 turn times with the 8086K, as that stands to prove more impactful.

They used to but Intel coolers are so bad that no one used them so instead of making one that was usable for the k CPU's they just stopped including them. At least the other guys include them still and 2 of the 3 are actually usable as coolers. Personally I would rather have some sort of cooler included so at least would be up and running if the high end air or water cooler was om back order or waiting on shipping at least can get the system built and running.Flunk - Monday, June 11, 2018 - link
The ones they sent out with the older -K series processors were a joke. My i5-2500K came with a cooler that couldn't even cool it within Intel's specs running stock in a cold room.mkaibear - Tuesday, June 12, 2018 - link
I'm still using the one which came with my 4790K and it works fine, and the one my 2500K came with also worked fine when I had it, even at 30C ambient temps in the middle of summer.Probably an installation error there Flunk.
(yes, I bought K series processors and never overclocked them, for both of these my intention was to downclock them for reduced heat and noise but never got round to it with the 2500K and the 4790K didn't really downclock very well so I couldn't be bothered!)

Absolutely incorrect. I installed tons of the stock Intel coolers on i5s and i7s and they work as specified for the stock settings of the CPUs plus were normally very quiet.SirMaster - Monday, June 11, 2018 - link
"K" CPUs con't come with heatsinks or fans... Neither does the 8700K or 8600K or 7700K, etc.Matthmaroo - Monday, June 11, 2018 - link
It’s been a while for you , I see - K series cpus have no coolerMemo.Ray - Monday, June 11, 2018 - link
Memo.Ray - Monday, June 11, 2018 - linkAs I mentioned in my comment in the other article a couple of days ago:
Intel managed to give away 8086 "binned" 8700K (AKA 8086K) and still make some money on top of it. win-win situation :D

And you miscalculated because you used the i7 8700 cost not the 8700K cost. They made maybe $300K on them.You know I have never seen anyone complain about say a 40th anniversary version of a car.

If it were more similar to the 4790K with a better thermal design (think devils canyon..) it's something I'd be interested in over the 8700K. It's not tho… and doesn't even come with a specialty cooler that might peak interest.. but rather "NO COOLER" at all.. I dunno..I think Intel missed the boat with this one.

Who *actually* thought, after so many years of Intel not giving coolers with it's "K" model variants, that this one might come with a bundled cooler? :)
