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.

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.

got rip off by Intel again Xd. little to no improvement. that is what their fab are for flexible manufacturingThe Chill Blueberry - Monday, June 11, 2018 - link
But that's not a new processor, it's just a binned i7-8700k. It's just pre-overclocked a bit and guaranteed stable.The Benjamins - Monday, June 11, 2018 - link
A bin that is a big let down, with no better 2-6 core turbos it makes this CPU only marginally better then the 8700k. they could of tried to have the other turbo speeds have some improvements.Dr. Swag - Monday, June 11, 2018 - link
This chip is obviously intended for OCing in which case it should be able to attend least hit 5 ghz.AutomaticTaco - Monday, June 11, 2018 - link
Simple enough solution. Don't buy one. Right?mr_tawan - Monday, June 11, 2018 - link
You know, this SKU is meant a collectible for their anniversary.I think they should gold plate the lid though :P

More INTEL non-innovation ....Death666Angel - Monday, June 11, 2018 - link
It's a whimsical anniversary celebration CPU. What were you expecting? It will only sell to people who want it for the novelty/collectors aspect. Anyone getting it for the performance delta deserves to lose their money.AutomaticTaco - Monday, June 11, 2018 - link
Or others who happen to be in the market for an upgrade now.Oxford Guy - Thursday, June 14, 2018 - link
As whimsical as roadkill.
