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.

    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.

    Ich frage mich, wie schnell der technologische Fortschritt voranschreitet. Der nächste Schritt ist das Streamen von einem Online-Casino, beispielsweise über https://casinoonlineschweiz24.com/software/merkur-... Es wird für alle Glücksspielenthusiasten mega aufregend sein Reply

    Do not save on this if you really need it, just start earning more. Apollo Slots is one of the leading online casinos in the South African online market. just go to the website https://casinolife.co.za/review/apollo-slots because it is safe, offers speedy payouts, has powerful and responsive support, and many more Reply

    Thank you for such a wonderful review. It is really important to understand in time that you need to save money. For example, I save money when I play using the minimum deposit: https://casinospieles.de/10-euro-einzahlung/ . This allows me to understand if this game really suits me without spending a lot of money on it. Reply
