Out of the box, Intel's limited edition Core i7-8086K processor commemorating 40 years of x86 computing can hit 5GHz without overclocking, via the chip's boost frequency. For those who are willing to pop the integrated heatspreader (IHS) off, however, much higher clocks are possible, as extreme overclocker Der8auer demonstrated by taking the chip north of 7GHz.
