As it is clearly stated on the box, the Core i9-12900KS is a "Special Edition" unlocked CPU so it is obvious this one will have both a premium price as well as limited availability.

According to Intel, the Core i9-12900KS is to be paired up with a Z690 chipset motherboard with the latest BIOS in order to get the most out of it. Specification-wise, the Core i9-12900KS is similar to the Core i9-12900K, featuring eight P- and eight E-cores, 24-threads, 125W PBP (241W maximum turbo power), and 30MB of Intel Smart Cache, but with a higher "up to 5.5GHz max turbo frequency with Intel Thermal Velocity Boost".

According to Intel, it should be available as of April 5th with a suggested retail price of $739 and is said to be available at retailers worldwide as a boxed version and integrated into systems from Intel's OEM partners.

“Intel continues to push the envelope for desktop gaming with the new 12th Gen Intel Core i9-12900KS processor. Based on Intel’s 12th Gen performance hybrid architecture, this processor can hit 5.5 GHz on up to two cores for the first time, giving the most extreme gamers the ability to maximize performance”, said Marcus Kennedy, general manager of Gaming, Creator & Esports Segment at Intel.

The CPU has already been spotted over at Newegg.com at $799, so some retailers might start selling it earlier, or at least start taking pre-orders.
