Core i9-12900KS Alder Lake

Core i9-12900KS the new Alder Lake

 Core i9-12900KS Alder Lake Specifications.

Core i9-12900KS Alder Lake Technical Data.

intel last 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.

It is crowned, by performance, as the fastest package of the entire market offer for desktop systems (of course, excluding workstations, based on Intel Xeon and AMD Threadripper chips), and it shows how well it It has been up to Intel to offer the leap to hybrid architecture with Alder Lake.

And what makes the Core i9-12900KS become the new king of the jungle? The first thing we notice when comparing it to the Core i9-12900K is that 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've probably dreamed of.

It is the consequence of a gentle but noticeable increase in the speed of the cores that make up the chip, both performance and efficiency cores.

Thus, among the information released by Intel and the infiltrations of the last few days, we have the possibility to reveal 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 cores of efficiency 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 (that is, megahertz), but rather also optimization for the maximum use of the wild force.

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

That allows the processor to reach its performance level surely, and also IIntel Adaptive Boost, which actively adjusts the performance of the processor at the moment we play, offering peaks of it at the moment they are precise.

The Core i9-12900KS package is complete 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 launched.

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

At this precise moment you are undoubtedly going to be asking yourself 2 essential questions, when and how much.

Since we quickly get rid of concerns, the Intel Core i9-12900KS will be free for purchase from next April 5 (rarely a couple of weeks before the arrival on the market of the AMD Ryzen 7 5800X3D, which also aims primarily at the gaming world)

ANDThe suggested value by Intel is 739 US dollars.

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

I don't think the title of your article matches the content hahaha. Just kidding, mainly because I had some doubts after reading the article.
