Intel's i7-8086K Hits 5.0GHz Out Of The Box

To kick off their keynote at Computex in Taiwan this year, Intel announced they were celebrating the 40th anniversary of the x86 processor with a bit of a bang: the Core i7-8086K, an anniversary CPU that runs at 4.0Ghz and can hit a turbo frequency of 5GHz out of the box.

Being a K-series CPU, the 8086K will be overclockable - although precisely how much headroom you have is completely unknown at this stage. Intel stressed in a follow-up release that the 8086K was a limited edition release, and while it would be sold through regular retailers, pricing and availability is unknown at this stage.

Intel didn't reveal whether all cores on the 8086K could be boosted to 5GHz, or whether only a few cores could reach those heights out of the box. The chip is compatible with only Turbo Boost 2.0, not 3.0, and that the chip would require a Intel-300 series motherboard.

The announcement was also followed by the official reveal of the Whiskey Lake and Amber Lake Y and U-series CPUs, which are targeted at the laptop/convertible market. A Dell XPS 13 was shown off with a quoted 20-plus hours of battery life, partially thanks to advancements in screen panels that use only 1W of power.

On the desktop side of the equation, although the X and S-series desktop CPUs will get a refresh by the end of this year. A 28-core CPU was also shown at the end of the keynote with all cores running at 5.0GHz, undoubtedly designed to compete with AMD's Threadripper offering. It's not known what socket the chip runs on, though.

    That's good... but does it hit 4.0ghz or 5.0ghz out of the box? I get it hits 5.0 when it's overclocked but that's not 'out of the box'. Can you fix the headline to reflect what you're writing please?

      I guess if the user doesn't have to do anything for it to hit that 5.0, even if it isn't the typical running speed, it's probably is considered "out of the box" spec.
      For me the more interesting question is how long can it maintain that upper limit, because if it's short lived then marketing at anything other than a 4.0 'with turbo' would be disingenuous.

      It means the baseline speed of all cores is 4.0Ghz, and the CPU will boost to a maximum of 5.0Ghz when deemed necessary. So, out of the box, the CPU will idle at 4.0Ghz, and hit 5Ghz when playing games.

      By comparison, the first Ryzen 1800X CPU would boost to 4.0Ghz, and had a base of 3.6Ghz out of the box.

        Thanks for the clarification (my last sentence came out wrong, was meant to have "if this is actually the case", sorry if it came across snarky).

    Until it immediately thermal throttles under an AVX workload down to 3.9 because Intel will again be using hemorrhoid cream as the thermal interface between the die and the IHS.

      Agreed, I just delidded my 4770k and replaced the TIM with liquid metal. With an AIO liquid cooler, all cores barely hit 40deg overclocked and under load. System stability is heaps better as well. I recon the inconsistency in overclocking capacity between the same chips comes down to the TIM they use.

    I'm still running my i7 2600K at 5ghz on a closed loop cooler. I've been doing this for the past 3yrs to force it to die so I can upgrade. Every day it takes the excessive voltage and heat in an affront to everything I believe in. -_-

    They showed a 28 core CPU with all 28 cores running at 5GHz.
    Really? Wow.
    That is far bigger news, that blows anything even on the drawing board out of the water and would pretty much double high end workstation performance. Is there any more info on this?
    We are currently running 22 core 2.2GHz machines, and this would be an amazing upgrade.

      Not at the time of writing, but can chase it up for sure.

        Presumably it dims all the lights in the neighbourhood when it's running / doubles as a space heater.

    Price and power consumption are also very important, a twin thread-ripper setup might still be better option (if cheaper/faster/cooler) since we are talking about heavily threaded desktop workloads here not gaming.
