Intel today officially unveiled the Core 12 (Alder Lake) processors, and today the results of overclocking the flagship of the series, the Core i9-12900K, appeared. According to the source, the CPU obeyed the frequency of 6.8 GHz, but only high-performance cores (P-cores, aka Golden Cove) worked on it.
Core i9-12900K is equipped with high performance and energy efficient cores. The latter (they are E-cores or Gracemont) started working at 5.3 GHz. For comparison, the base frequencies of the P- and E-cores are 5.2 and 3.9 GHz, respectively. That is, in the first case, the frequency increased by 31%, in the second – by 36%.
The booth used for overclocking included an ASRock Z690 Aqua OC Edition motherboard, a pair of DDR5-4800 modules that were also overclocked (up to DDR5-6200), a liquid nitrogen cooling system, and an EVGA SuperNOVA 1600W power supply.
The overclocked processor set two world records in Geekbench 4 and Geekbench 5. In Geekbench 4, the processor scored 11,669 points in a single-threaded test and 93,232 points in a multi-threaded one. Geekbench 5 results – 2740 and 26 649 points, respectively. The result in XTU 2.0 is 12,765 points, but in this case we had to lower the frequency to 6.7 GHz for more stable operation and a successful test completion. In comparison, the previous Geekbench 5 records were set by the Core i9-11900K (2309 points in a single-threaded test) and the Ryzen 9 5950X (20,929 points in a multi-threaded test).
