There are currently four processors in the world verified to be capable of surpassing the 9GHz barrier, and one of them just recently took the all-time record of 9121.61MHz, beating the previous record by a mere 4 megahertz (that’s 0.004GHz, to give you the perspective).
New Core i9 World Record
The new record now comes from a Chinese-based team led by ‘wytiwx’, and its 9.12GHz record barely dethroned the previous one set by ‘elmor’, another renowned overclocker in the scene. The weapon of choice is, as usual, Intel’s Raptor Lake-based Core i9-14900KF processor – despite it not being the newest chip by now, it is still the fastest out-of-the-box in terms of clock speeds, so that makes it ideal for overclockers to keep pushing the very limits of this chip (and similar ones like i9-14900KS) under extreme overclocking conditions.
Notably, these two records are the only two in the HWBot database that has been recorded using exotic Liquid Helium (LH2) cooling. LH2 is even cooler than liquid nitrogen (LN2), which is a commonly used and easily obtainable coolant for extreme overclocking; and that extra low temperatures give these silicon just a tiny bit more stability to achieve even higher clock speeds. For comparison, the database’s best LN2 record is currently capped at 8851.57MHz, through the same chip as the current world record holder.
To help with stability, any non-essential features of the CPU has been disabled, including E-cores (leaving only 8 P-cores active), hyperthreading, and a single-channel 16GB DDR5 memory. As the F-series chip, it also lacks onboard graphics – another potential avenue of instability in such conditions.
As the chart above shows, CPUs are getting increasingly difficult to overclock in this day and age, in part due to physical limitations of how fast the silicon can operate without producing excessive heat. That’s why instructions per clock, or IPC in short, is a much more important metric today, along with power efficiency – both that comes with practical benefits, which extreme clock speeds aren’t designed for.
Pokdepinion: That is very close. Perhaps elmor want to give it another try?
