 Core i9-12900KS Alder Lake Specifications.

Core i9-12900KS Alder Lake Technical Data.

Intel finally officially announced the Core i9-12900KS processor, a chip that we were waiting for, since it was seen in a benchmark a few days ago.

In terms of performance, it is crowned as the fastest package in the entire market offering for desktop systems (of course, excluding workstations, based on Intel Xeon and AMD Threadripper chips), and it shows how well Intel has done by offering the jump to hybrid architecture with Alder Lake.

And what makes the Core i9-12900KS the new king of the jungle? The first thing we notice when comparing it with the Core i9-12900K, the thing is Its maximum continuity in turbo mode rose from 5.3 to 5.5 gigahertz on 2 of its cores.

Core i9-12900KS Alder Lake: A leap, as you probably dreamed.

It is the consequence of a gentle but noticeable increase in the agility of the nuclei that make up the chip, both performance and effectiveness.

In this way, among the information released by Intel and the leaks of the last few days, we have the opportunity to break down the performance of the cores of this Core i9-12900KS:

  • 2 performance cores with a speed of up to 5.5 gigahertz (base 3.4 GHz).
  • Six performance cores with a speed of up to 5.2 gigahertz (base 3.4 GHz).
  • Eight high-performance cores with a speed of up to 4 gigahertz (base 2.5 GHz).

Core i9-12900KS Alder Lake

Core i9-12900KS Alder Lake – Essential role in this optimization.

There are other elements that also play an essential role in this optimization in performance, which is not only barbaric (i.e. megahertz), but also optimization for maximum use of the wild force.

Specifically, this Intel Core i9-12900KS holds its own quite effectively in the technologies of Intel Thermal Velocity Boost.

Which allows the processor to reach its performance limit surely, and also IIntel Adaptive Boost, which actively adjusts processor performance while playing, offering peaks when necessary.

The encapsulation of the Core i9-12900KS is completed with what Intel calls 30 megabytes of cache capable, which fit with the 30 megabytes of L3 cache that we saw in the benchmark a few days ago, and to which we should add the 14 megabytes of L2 cache that the Cinebench R23 test revealed.

All of the above with a TDP of 150 watts, 25 more than its "denied" brother, the Core i9-12900K.

Right now you are undoubtedly asking yourself two essential questions: when and how much.

Now that we've got our concerns out of the way, the Intel Core i9-12900KS will be available for purchase. from next April 5th (just a couple of weeks before the arrival on the market of the AMD Ryzen 7 5800X3D, which is also primarily aimed at the world of gaming)

ANDIntel's suggested retail price is $739..

We will still have to wait to understand its conversion to euros, but let's keep in mind that the suggested price of the 12900K is 679.90 euros.
