Additional data about Intel’s 14th Gen Raptor Lake-S Refresh has surfaced. It looks like the higher-end SKUs will up the clocks by 200MHz, hitting the 6GHz mark and then some. According to Moore’s Law is Dead, the Core i9-14900K will have a boost clock of 6GHz, up from 5.8GHz on the 13900K. As with the previous two lineups, the Core i9-14900KS variant will be released a year later with a boost clock of 6.2GHz (vs. 6.0GHz on the 12900KS).
Intel’s Core processors have a complex boost algorithm that ramps up the fastest cores much higher than the rest. The Core i9-14900K and 14900KS should have a Turbo Boost Max Technology 3.0 (TBM3) of 5.9GHz and 6.1GHz respectively. All but the two fastest cores will top out at 5.6GHz. If sufficient thermal headroom is available, the two fastest cores can go as high as 6GHz and 6.2GHz on the 14900K and 14900KS, respectively. This is known as Thermal Velocity Boost (TVB).
In addition to TBM3 and TVB, Adaptive Boost is another smart boost governor that boosts all the cores (or nearly all of them) to the spec single boost clock. Technically, this value should be lower than the TBM3, but most OEMs push it as high as the spec boost. Further reading:
