Intel 12th Gen “Alder Lake-S” Core i9-12900K Hits A Turbo Clock Of 5.3 GHz

Recent leaks show that Intel’s flagship 12th Gen “Alder Lake-S” Core i9-12900K is capable of achieving a boost clock speed of up to 5.3 GHz. It operates on a base clock of 3.9 GHz.


Intel’s Alder Lake will reap benefits from the Hybrid technology. The technology is based upon small and big cores. Both the cores share the same instruction sets and model-specific registers but operate on different computational powers and overheads. Big cores have higher throughput and clock speeds, while the small ones are extremely power efficient. The flagship Core i9-12900K consists of 8 big cores and 8 small cores. It achieves a boost clock speed of up to 5.3 GHz, which is less than the rumored 5.5 GHz boost clock speed.

A Twitter user, 9950pro, discovered a post on The user was able to calculate Cinebench R20 multi-core test benchmark results for the Core i9-12900K, Core i7-12700K, and the Core i5-12600K using his information on Qualification Sample and the Cinebench R20 multi-core test score of the engineering sample of the i9-12900K.

The scores are:

Core i9-12900K (ES2): 9300+

Core i9-12900K (QS calculated): 11300+

Core i7-12700K (QS): 9500+

Core i5-12600K (QS): 7400+

The i9-12900K has outperformed AMD Ryzen 5950X by over 900 points. A higher turbo clock was used to calculate the i9’s score.

Intel Alder Lake

In a previous leak, the Twitter user YuuKi_AnS got information about all the current bugs discovered on mobile Alder Lake Engineering Samples. The user also confirmed that Windows 11 was required to benefit from Intel’s Hybrid Technology.

It is expected that Intel Alder Lake processors will arrive in Q4 2022, and that too with DDR5 memory and PCIe Gen5 standard support.
