Echoing George Mallory's apparent response of "Because it's there" when asked why he wanted to climb Everest, super-serious overclockers need no reason
for pushing hardware into uncharted territory. Armed with years of experience and no small amount of liquid helium, one team of tweakers has pushed what Intel CPUs can reach just that little bit further, with a Core i9 14900K reaching an [[link]] utterly remarkable 9.1 GHz.
Word of the achievement was reported by , which was part of the team behind the endeavour, and you can read more details of the overclocking result in the . On face value, it might seem quite simple to do: take a standard ROG Maximus Z790 Apex motherboard, slap some Corsair Vengeance DDR4 and a GeForce RTX 3050 into it, along with an .

The latter normally maxes out at 6.0 GHz for a single P-core, so how exactly did the team manage to increase that by 52%? For starters, they disabled all the E-cores before setting about tweaking all kinds of BIOS settings. Somewhat obviously, using an ordinary CPU cooler was kind of out of the question—the 14900K runs hot at the best of times, so at 9.1 GHz, it's clearly going to replicate the surface of the Sun.
Enter stage left, an awful lot of liquid helium. Under atmospheric pressure, it boils at −269 °C (−452 °F), making it ideal for removing heat from the CPU very quickly. It also just so happens to look extremely awesome while doing so, with vast clouds of condensation adding to the sheer coolness of it all (pun not intended).
It's worth noting that the record of 9.1 GHz was achieved on a single P-core, but that's normal for such attempts; the same is true of the [[link]] overall test conditions. Think of it as being like top fuel drag racing—super impressive stuff, if not exactly eminently useful to mere mortals.
You might wonder if it'll be possible to hit 10 GHz with a current AMD or Intel chip. The answer is almost certainly no, and that's because there's an with silicon-based transistors, once they're switching at that rate in a standard processor. Perhaps it might be different with other materials, but we're going to [[link]] be .
Eventually, that will change, of course, and you can be sure of one thing when that does happen—overclockers will be on hand with their liquid helium to see what records they break with those chips. Why? Because they can.
