ASUS Overclocks Intel 13th Gen Raptor Lake Core i9 CPU To A Blazing 9GHz World Record
An Intel Core i9-13900K has been nudged past 9GHz, to achieve a CPU clock speed world record. En-route, the current flagship Intel 13th Gen Core ‘Raptor Lake’ processor grabbed CPU performance world records in benchmarks like PiFast and SuperPi. Intel boasts that this is the second time since launch, just three months ago, that the 13900K has leapfrogged a longstanding processor overclocking frequency world record.
Intel worked with the ASUS overclocking team for the headlining 9GHz OC achievement. Readers won’t be surprised that extreme cooling was applied to the flagship Intel CPU for it to achieve this momentous clock speed. Specifically, the processor was bathed in liquid helium while voltages were tweaked and clocks were ramped. Helium’s boiling point is -270°C / -452°F, and is thus liquid helium is significantly colder than liquid nitrogen (boiling point -196°C / -320°F). Liquid helium is probably the ultimate choice for extreme OC feats, but it is a lot more expensive. Under the liquid helium pot, the CPU temperature was measured to be a pretty consistent -250°C.
The liquid helium supply was copious enough to allow the ASUS OC team to achieve new records in PiFast (6.85 seconds) and SuperPi 1M (3.822 seconds). However, these runs weren’t completed at a CPU clock of >9GHz. Overclocker SafeDisk achieved his PiFast record with the 13900K running at a still formidable 8.44GHz, for example.
