Intel's keynote address at Computex 2018 came with a few surprises, but none were more surprising to the crowd than the demonstration of a 28-core workstation-class processor running at 5GHz. Intel says the new chip will come to market in Q4 of 2018. Before the event, Intel pre-briefed us about the 28-core model, but the company didn't disclose that it would come bearing a beastly all-core 5GHz frequency. The impressive display of multi-threaded performance probably consumed a hideous amount of power, which wouldn't lend itself well to a reasonable TDP rating for the processor. As such, we assume the processor was overclocked for the presentation.
Intel's 14nm++ process has already proven that it can sustain 5GHz easily, even with all cores active, on six-core models. Even novice overclockers can achieve a 5.0 GHz overclock on many standard off-the-shelf K-series Coffee Lake processors. But processors with higher core counts, such as the 28-core model Intel had on display, often can't reach such high frequencies on all cores, although dedicated tuning can certainly squeeze out impressive single-core frequencies.
