This would theoretically be the Core i9-12900KS, and according to sources who have spoken with VideoCardz, it will be a pre-built version (high performance 12900K chips capable of reaching higher clock speeds above the guaranteed baseline performance) of the CPU capable of achieving an all-core boost of 5.2GHz instead of 5GHz of the current 12900K.
However, as VideoCardz points out, the 12900K’s all-core Turbo obviously depends on the workload, and generally the CPU hits around 4.85GHz to 4.9GHz across all cores in most reviews. So we could reasonably expect the 12900KS (if it is going to happen) to reach just above 5GHz, or maybe 5.1GHz typically. It is, of course, across all 8 performance cores.
Issuing a KS variant of its flagship is not a new thing for Intel, though the chip giant did not with its two previous generations of processors. Last time it happened was with Core i9-9900KS, two years ago, although there was brief speculation in a 10900KS for Comet Lake (a Rocket Lake take on ‘KS’ were not rumors, but then the 11th generation had a relatively short time in the spotlight).
VideoCardz claims that the alleged Core i9-12900KS is being tested by motherboard manufacturers right now.
Analysis: Could the 12900KS be Intel’s response to AMD’s rumored CES launch?
If the 12900KS is really being tested as suggested, then a release is probably not far off, and as VideoCardz theorizes, we might be looking at a disclosure of the CPU on CES 2022.
Of course, whether this supercharged flagship variant shows up, we’ll just have to wait and see, but keep in mind that AMD is rumored to be preparing to launch updated Zen 3 CPUs with 3D V-cache (or vertical cache) tech. And so this could potentially be Intel’s response to the renewed Ryzen processors – just maybe Team Blue gets a little worried that the new AMD CPUs could steal some of Alder Lake’s current thunder?
AMD promises ‘up to’ 15% performance improvements in games with 3D V-Cache-toting CPUs, but we do not know how realistic these claims are until the new Ryzen chips are actually out and benchmarked across a range of games , of course.
