YuuKi AnS, a Chinese hardware blogger who previously released photos and exclusive details about Intel Sapphire Rapids, mentions clandestinely selling Intel's Core i9-12900K Alder Lake CPU (QS) qualifying samples in China. The present pricing is between 1,064.95 dollars and 1,157.55 dollars.

Although Intel has not even set a precise launch date for Alder Lake, it is claimed that the heterogeneous CPUs would land in the beginning of 2021 or 2022, with all possible delays. Recent reports regarding samples being sold on the Chinese market implies that retail availability might be established before the end of the year.

The core i9-12900K is composed of 16 core components, 8 Golden Cove and 8 Gracemont core components. There is 30MB L3 cache available in the Alder Lake flagship SKY. The Core i9-12900K offers an unlocked overclocking multiplier. It's a K-series SKU. 

The flagship will (not surprisingly) be called Core i9-12900K in the 12th Gen Core lineup series, and will succeed the i9-11900K with the maximum configuration of 8+8 (P+E), unlocked multipliers, the highest cache, and the fastest clock speed. The P (performance) core ("Golden Cove" core) is clocked at 5.30 GHz and the all-core core is clocked at 5.00 GHz / 8 cores. Its gracemont core (energy efficient) is clocked at 3.90 GHz (1 to 4 cores boost) with the all-core boot of 3.70 GHz / 8 cores. The silicon's total L3 cache is 30 MB. The TDP is 125 W for the i9-12900K (PL1) and 228 W PL2 for this product. Intel is introducing numerous new overclocking capabilities, including memory gear ratios.

The 12th gen core i7 is configured as 8+4 core (P+E), has somewhat lower clock rates than the i9 core, and some boost functions may be missing. The Core i7-12700K is the highest geared Core i7. The highest P-core boost frequency is 5.00 GHz and the all-core booster is 4.70 GHz, while the top boost for E-cores is 3.80 GHz with an all-core of 3.60. The chip contains 25 MB of L3 and is similar to the i9-12900K for PL1 and PL2 values.

Up to 6+4 core (P+E) cores are supplied for the Core i5 series. The unlocked Core i5-12600K operates the P-cores to 4.90 GHz with an all Core of up to 4.50 GHz, while the E-cores are up to 3.60 GHz with an entire Core of up to 3.40 GHz. 20 MB of L3 cache, and the same 125 W PL1 and 228 W PL2 values as the other two unlocked parts.
