Intel Alder Lake: Overclocked To 6.8 GHz, A Core i9-12900K Breaks All Speed Records

Give a new Intel processor to an overclocker with liquid nitrogen, and you can expect the chip to reach record-breaking frequencies. The Intel Core i9-12900K was the prime candidate to reach new heights.

Just hours after Intel officially unveiled the 12th generation of its highly anticipated desktop processors, an overclocker has already tortured the Core i9-12900K Alder Lake, which seems to have great potential for overclocking.

The configuration used includes an ASRock Z690 Aqua OC Edition motherboard paired with DDR5-4800 RAM from Klevv (overclocked to 6200 MHz), and it was all powered by an EVGA Supernova 1600W.

As a reminder, the chip has a total of 16 cores and 24 threads. The cores are divided into 8 Golden Cove P cores and 8 Gracemont E cores, which go up to a maximum of 5.2 GHz and 3.9 GHz respectively in a typical machine.

However, Allen “Splave” Golibersuch of Tom’s Hardware has already managed to push the chip to its limits, pushing its Performance cores to 6.8 GHz, and its Efficiency cores to 5.3 GHz.


The 12900K overclocked to 6.8 GHz set new records on both Geekbench 4 and Geekbench 5 for single-core, with scores of 11,669 and 2,740 respectively.

This improves on the previous single-core world record set by the previous generation Intel Core i9-11900K by 19%.

In multi-core in the 16-core category, the chip also smashes previous scores with 93,232 and 26,649 respectively.

In multi-core, the Intel Core i9-12900K also breaks the record held by the AMD Ryzen 5950X with a 27% higher score.

This is no surprise, as the Intel Core i9-12900K was already tested before its launch, and the first benchmarks already showed that it dominated its red competitor.

This overclocking was of course done by a professional with liquid nitrogen and not a traditional ventirad or watercooling, so it is better to avoid trying to push your processor that far at home.

Individuals will also have to pay attention to the high energy consumption of the chip, since this is a real disaster for the environment.

Overclocking the processor easily turns it into a radiator with a power consumption that easily exceeds 300W or even 400W.
