Intel Core i9-12900K overclocked to 6.8GHz sets new world record

Intel has finally pulled the curtain on its 12th Gen Core series, unveiling its first desktop hybrid processors. During the launch event yesterday evening, professional overclocker “Splave” had the chance to tinker with the Core i9-12900K, pulling off a 6.8GHz overclock and breaking the world record on the Geekbench 5 single-core benchmark.

As reported by Tom’s Hardware, residential overclocker “Splave” was able to push the 12900K’s P-cores to 6.8GHz and the E-cores to 5.3GHz, as the ring/cache ratio was pushed up to 5.5GHz. That’s a 31% and 36% increase in the P-core and E-core clock speed, respectively. The system also used an ASRock Z690 Aqua OC Edition with two Klevv DDR5-4800 memory modules overclocked to DDR5-6200 C34 and der8auer’s Reaktor 2.0 LN2 pot. To power the system, Splave used an EVGA SuperNova 1600W PSU.

To run XTU 2.0, Splave had to downclock the processor to 6.7GHz, but the system still scored a whopping 12,765 points. That’s just over 1000 points shy of the world record set by an Intel Xeon W-3175X, which scored 13,777 points. As for Geekbench 4, the overclocked Core i9-12900K also got some really high scores, achieving 11,669 in the single-core test and 93,232 in the multi-core test.

Lastly, running the Geekbench 5 benchmark, the system broke the previous record of 2,320 set by an AMD Ryzen 9 5950X, scoring 2,740 points. On the multi-core test, the system scored 26,649 points, pretty close to the Ryzen Threadripper 3970X.

KitGuru says: If you get one, will you be overclocking your Alder Lake processor? How high are you hoping to push its clock speeds?
