Intel Displays Core i9-12900KS With 5.5 GHz Boost Clock, 5.2 GHz All-Core

A few hours ago, AMD showed a demo of its new Ryzen 7 5800X3D beating the Core i9-12900K slightly in a few gaming benchmarks, but Intel obviously has its response ready. During Intel's CES 2022 keynote, Gregory Bryant demoed the company's unreleased Core i9-12900KS that it says will hit 5.5 GHz on a single core right out of the box. Additionally, it will sustain more than 5GHz during multi-core workloads, which Intel demoed during a Hitman 3 gaming session. 

The demo comes on the heels of Intel's teaser tweet earlier this week, and the chip is already in production as Intel readies it for release "to OEM customers" later this quarter. The "S" suffix stands for Special Edition, denoting that this is a limited-run CPU that's binned for the ultimate performance possible. Intel's Core i9-9900KS was the last Special Edition chip, hitting 5.0 GHz on all cores, but it arrived back in 2019. 

Intel is obviously upping the ante here with a 5.5 GHz boost on a single core, along with the ability to hit 5.2 GHz on all cores during gaming workloads.

Intel conducted a real-time demo of the chip with the HWInfo monitoring utility open to show the clock rates for all eight P-cores and eight E-Cores. Below we can see the P-cores operating at 5.2 GHz while the E-cores run at 4.0 GHz. 

Unfortunately, we didn't see the apparently elusive 5.5 GHz during the demo.

Intel didn't share any other details, like the type of cooling required or pricing. Bryant did say the chip will ship to OEM customers this quarter, which leaves some questions as to whether or not this chip will come to retail outlets. We'll follow up as we learn more.

    Cooled by what this time? Intel seems to have a habit of not fully disclosing the setup as evidenced by the hidden chiller fiasco a couple years back.

    If this Nuclear Reactor of a CPU will not beat the 5800X3D in gaming, it will be a huge failure for intel and Alder Lake, because both are claiming to be the best CPU for gaming (which is ironic and funny).

    Even if it does beat the 5800X3D, I suspect it will be by less than 5% and at double the price (plus that heat and power consumption).

    I can't wait for 5800X3D vs 12900KS reviews from HUB and GN.

    Its just more vaporware, talk about cherry picking they cant have many that reach those clocks. Just trying to steal AMD's thunder

    KS again... I guess theres still people with lots and lost of money, who have no issue paying the extra premium for a 2~5% higher performance.

    But as always better wait for other reviewers to test this new KS stuff.
