– New world record: 9.2 GHz single-core on Intel Core i9-14900KF, beating the 9.1 GHz mark from August 2025, achieved with extreme voltage and sub-zero liquid helium cooling.
– Not sustainable for everyday use: frequencies are for validation runs lasting only seconds, with a single P-core enabled and no power limits.
– Stock performance note: the 24-core 14900KF can boost to about 6 GHz on stock settings (all-core).
– Historical context: AMD previously led frequency records with LN2/helium cooling (FX-8370 era); Intel reclaimed the crown with Raptor Lake, highlighting advances in silicon binning and extreme cooling.
An Intel Core i9-14900KF has set a new benchmark for desktop CPU overclocking, reaching 9.2GHz and surpassing the previous 9.1GHz world record established in August 2025. The new record, apparently set a few weeks ago, relies on extreme voltage adjustments and sub-zero liquid helium cooling that are far outside the scope of everyday PC use. Before that, the Intel Core i9-13900K was the first consumer processor to cross the 9GHz mark.
Record-breaking system:
For years, AMD held the CPU frequency world record with heavily overclocked AMD FX-8370 and other FX-series chips dominating the rankings with liquid nitrogen and helium cooling. Intel only managed to reclaim the crown with its Raptor Lake processors. On stock settings, the 24-core 14900KF can boost to 6GHz.
Technical notes and validation
The achievement highlights how far modern silicon binning and extreme cooling techniques have progressed, although such frequencies are only sustainable for validation runs lasting seconds. The overclock was performed with just a single P-core enabled and power limits removed entirely to maximize single-core frequency potential. HWBot, CPU-Z Validator
