Intel’s 12th-generation Core Alder Lake-S desktop processor has been officially released. This series of products are designed with large and small cores, and are the first to support DDR5 memory, PCIe 5.0 channels, and are manufactured using Intel 7-node technology with a 10nm process. Allen’Splave’ Golibersuch overclocked the flagship model Core i9-12900K CPU with liquid nitrogen for the first time during the live broadcast.
Moreover, this processor has 8 high-performance P large cores + 8 performance E small cores, and the default turbo frequency can reach 5.2GHz and 3.9GHz respectively. After using liquid nitrogen to cool the overclocking, the main frequency of the large and small cores reached 6.8GHz and 5.3GHz respectively, which were increased by 31% and 36% respectively compared to before overclocking. In addition, the ring/cach frequency is also overclocked to 5.5GHz.

Furthermore, it uses ASRock Z690 Aqua OC Edition limited edition motherboard. The circuits on the motherboard are sealed with glue to prevent short circuits caused by condensed water. This motherboard only provides two DIMM memory slots, the purpose is to improve memory overclocking potential. It is worth noting that the overclocker Splave also overclocked the DDR5 memory to 6200MHz by the way, and the timing is as low as CL34. In addition, players use EVGA SuperNOVA 1600W power supply for power supply.
Besides, the Splave used the overclocked i9-12900K CPU to conduct a Geekbench 4/5 benchmark test, breaking the world record for a 16-core processor. After overclocking this CPU, the single-core score is as high as 2740 points, and the multi-core score is 26649 points. In addition, in Intel XTU 2.0 software, the score reached 12765 points. This player said that when performing XTU 2.0 running points, the processor’s large core frequency must be reduced to 6.7GHz, otherwise it is unstable and the test cannot be completed.
The overclocking results of the Intel i9-12900K processor are significantly improved compared to the previous 8-core i9-11900K and 16-core AMD R9-5950X processors. Compared with the former, the single-core performance has increased by 19%, with multi-core performance, it is improved by 27%. At present, Intel’s 12th-generation Core desktop processors have started pre-sales, and the products are expected to start shipping on November 10.
