Intel's 12th Gen Core i9 12900KS flagship is out in the wild

Intel’s upcoming 12th Gen flagship CPU, the Core i9 12900KS, is already in the hands of users. This indicates that the launch is imminent and if rumours are true, the 12900KS will launch later in March.

According to a post at overclocking.com (via Tom’s Hardware) a user by the name of Daginatsuko has already received a retail 12900KS that they purchased prior to the listing being removed. The packing certainly looks well presented, complete with the inclusion of a mock wafer.

The overclocking.com post includes a screenshot of the CPU paired with an Asus motherboard. An idle BIOS temperature of 78c is notable, though perhaps just the result of a bad cooler mount. It's not a leap to suggest that nothing short of a top end air cooler or AIO will be sufficient to keep this CPU from throttling under an all core load. We’ll have to wait and see if there will be any overclocking headroom. At a 5.5GHz single core boost, it would seem as though that’s about the maximum on ambient cooling.

The BIOS screenshot includes what Asus calls the ‘SP’ rating which is essentially a measure of the quality of a CPU. It serves as an indicator of what kind of overclocking potential it may have based on its voltage and frequency points. A higher number is better and at 155, this 12900KS sample is very good indeed. 

The Core i9 12900KS was first teased by Intel during its CES 2022 presentation. It is proof of the strength of Intel’s ‘7’ process. It comes with a 5.5GHz single-core boost clock, which is 300MHz higher than the Core i9 12900K. The KS can boost to up to 5.2GHz across all cores. This is an increase of 200MHz over the 5.0GHz boost clock of the 12900K.

We don’t yet know what the purchase price was or the TDP of the 12900KS, but its safe to say it will carry quite a price premium over the base 12900K. The standard 12900K comes with a 241W PL2 rating so we’d expect the 12900KS to be able to pull more than that, perhaps even 300W. That’s high to be sure but enthusiasts chasing the best possible performance aren’t going to be bothered by a few extra watts. It's all about performance.
