The news has been out that a certain Chi-Kui Lam has broken a world record by speeding up his Intel Core i7 6700K Skylake processor by 75.64 percent and reaching the frequency of 7025.7 MHz. And that’s true---in a sense.
The caveat is that the record only applies to the current Intel processor architecture, named Skylake. When it comes to the absolute highest frequencies achieved by overclocking retail processors, Lam’s doesn’t come even close.
