Overclocking Performance: CPU 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. Running at 5.1 GHz incurred rather high temperatures however, 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 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.
FCAT Processing
3DPM v2.1
Dolphin v5
DigiCortex v1.20
Blender
POV-Ray
Cinebench R15 ST
Cinebench R15 MT
7-zip
TrueCrypt
GeekBench 4 ST
GeekBench 4 MT
For everything except the most lightly threaded workloads, overclocking the 8086K to a flat-out 5GHz shows some reasonable gains. These results aren't you couldn't already extrapolate based on the clockspeeds, but it's nice to put theory to practice. It also highlights the unfortunate shortcoming of the CPU: being able to turbo one thread to 5GHz just isn't that useful, since you'll very rarely have a complete system workload that allows it, even if the heaviest workload is single-threaded. The 8086K simply begs to be run at a flat-out 5GHz to get the most out of its capabilities.

It seems like the only good reason to buy this processor would be for the preferential binning - it's kind of like a manufacturer official version of Silicon Lottery.xpto - Thursday, June 14, 2018 - link

well i know and few more that anatech are and clear long time amd support and cant make test without raise amd gpus and cpus someway better.sad...
but we are not idiots
its clear that both 6-core cpus 870k0 and 8086 are much better cpus than amds 8-core ryzen 2700x. that is clear fact
2700x is 8-core and still loose 3dmarks what is historical.. bcoz never bfore cpu that own more cores LOOSE cpu wich have less them.
its tell clear that ryzen 2700x is weak and also mem problem show it.
2700x cant handle high timing and hertz,
2700x is better and really shod be for mathematic apz,but as i say ITS 8-CORE CPU.
still it loose many test.
and for thouse importants games and 3dmarks its loose and clear.
when intels ALSO 8-core cpu guess 9700k release we really see how bad 2700z is.
i can say that 8-core 2700x loose clear for intels 9700k 8-core cpu.
ok..then 6700k vs 8086 cpu
well its clear that 8086 is better than 8700k,bcoz 8086 is hand picket cpus and oc'd better than 8700k.
so its mean 8086 ov'c higher,running lower heat ...exmaple all 8086 ov'd easily 5ghz, many 8700k not. only best.. and i took 24/7 use.
sure if you get good 8700k its different,but if different is example anatech saying 75$ that i can get good cpu i pay it for joy!
if you want best gaming rig buy:
asus hero x
2x8gb 4000mhz cl17 mem
8086 or 8700k cpu and ocäd it about 5ghz
buy more nvidia gtx 1080 ti
then u have gaming rig that amd cant beat near 2 years...think about it...
gtx 1080 ti is old shit and amd vega only few month old still no chance.

FYI - On the overclocking CPU page - GeekBench MT chart is a duplicate of the CineBench MT chart.sarahberard - Wednesday, June 20, 2018 - link
Hello I am so delighted I located your blog, I was watching on google for something else, greatsarahberard - Wednesday, June 20, 2018 - link
Your site fantastic, superior quality succeed... http://best-penis-pump.com/">.none12345 - Thursday, June 21, 2018 - link
I wasnt expecting much out of the 8086k over the 8700k... but this is truely underwhelming. Only a single core turbo boost? I was expecting all the boost tiers to be higher. And same tdp....so there goes it doing anything more at stock.I wasnt going to buy one anyway....so i guess it doesnt matter. I completely agree that intel could have and should have done more.
