After the article in which it was said about the first acquisitions of the new flagship from Intel, one enthusiast, which was lucky to get a sample of Core i9-12900ks even before Intel officially announced it. Core i9-12900KS is the flagship processor ALDER Lake-S with 16 cores and 24 threads, characterized by an increased clock frequency and power, decided to test it.

The fast test in Cinebench R23 confirms that the processor has a maximum clock frequency of 5.5 GHz for two performance nuclei and 5.2 GHz for all eight cores. It seems that effective kernels accelerate to 4.0 GHz.

CPU-Z data confirm that the processor has increased PBP (PL1) to 150 W, which is an increase of 25 W compared to the original 12900K SKU. In addition, the CPU monitoring tool does not list the AVX-512 instructions, confirming that Intel really separated this part from silicon.

According to the test provided by Seby, Core i9-12900Ks dials 2162 points in a single-core and 29164 points in a multi-core test.

Tom's Hardware quickly calculated some results with other high-performance components, such as 12900K with DDR5 and DDR4 memory, as well as Ryzen 9 5950x, flagship processors Zen3 from AMD:

In the stock of Core i9-12900Ks by 29.6% faster than Ryzen 9 5950x in a single-core test and 9.7% faster in multi-core. Please note, however, that this is not a comparison of apples with apples, as Tom's Hardware uses slower memory (Seby: DDR5-6200 on 32-38-38-76, Tom's: DDR5-4400 36-36-36-72).
