Intel's new top-of-the-line Alder Lake CPU Core i9-12900K was able to achieve new single-core and multi-core benchmark world records after hitting extremely high clock speeds of up to 6.8 GHz with a liquid cooling solution.

Just hours after Intel has officially unveiled the 12th generation of its highly anticipated desktop CPUs, a tinkerer has already put the new Alder Lake flagship processor Core i9-12900K through its paces and was able to set new performance records with an extreme cooling solution and aggressive overclocking. According to an article by Tom's Hardware, Allen "Splave" Golibersuch managed to overclock the Golden Cove performance cores of the i9-12900K to a spectacular 6.8 GHz, while the clock frequency of the more efficient Gracemont cores was increased to 5.3 GHz.

Splave utilized a particular version of the ASRock Z690 motherboard, a 1600W EVGA SuperNova PSU and overclocked DDR5 memory. The article does not contain any info regarding the temperatures and power consumption during this benchmark, but it seems likely that this is more of an experimental build. In Geekbench 4, this configuration achieved a single-core score of 11,669 points, while Geekbench 5 measured an impressive 2,740 points for the Core i9-12900K's single-core performance.

The previous single-core record set by the Intel Core i9-11900K (from US$544 on Amazon) was therefore improved by 19%, but the multi-core benchmark results were even better. In the Geekbench 4 and Geekbench 5 multi-core benchmarks, the Intel Core i9-12900K scored 93,232 and 26,649 points respectively. That is 27% better than the previous record-holding CPU with 16 cores, which was the AMD Ryzen 9 5950X. It will be exciting to see whether AMD's upcoming Ryzen CPUs will be able match or even surpass the formidable overclocking performance of the new Intel Core i9-12900K.

My fascination for technology goes back a long way to the Pentium II era. Modding, overclocking and treasuring computer hardware has since become an integral part of my life. As a student, I further developed a keen interest in mobile technologies that can make the stressful college life so much easier. After I fell in love with the creation of digital content while working in a marketing position, I now scour the web to bring you the most exciting topics in the world of tech. Outside the office, I’m particularly passionate about motorsports and mountain biking.
