Update 3/28: Following Newegg’s flub on Friday, Intel today is now (finally) officially announcing the Core i9-12900KS. The company’s new flagship consumer desktop chip will be going on sale next Tuesday, April 5th, with a recommended price of $739.
In terms of specifications, Newegg’s posting has turned out to be spot-on, with a maximum turbo clock of 5.5GHz and an all-core turbo clock of 5.2GHz. As were the 150 Watt base TDP and 241 Watt turbo TDP. All of which stands to make this Intel’s fastest consumer desktop chip yet, and one of the more power hungry.
It should be noted that Intel typically lists their chip prices in quantities of 1000 units. So while Intel’s official $739 price tag is lower than the $799 price in Newegg’s initial listing, it’s very likely that the retail price for the chip will land near or at $799 anyhow – though we’ll know for sure come April 5th.
Finally, availability for the i9-12900KS should be better than past Intel special edition chips (e.g. 9900KS). In our conversations with the company, we’ve learned that the goal of the 12900KS is to be more available than previous editions. It’s still a super small part of Intel’s overall Alder Lake offering (we’re hearing it’s a sub 1% of all chips can achieve Intel’s metrics for it), but the internal goal at least is to make sure it’s on more shelves this time.
The rest of the original story, updated with final figures and prices, follows below.
Long expected from Intel, the Core i9-12900KS is now out of the bag thanks to an apparently accidental listing from Newegg. The major PC parts retailer listed the unannounced Intel chip for sale and began taking orders earlier this morning. pulling it a couple of hours later. But with the scale and popularity of Newegg – as well as having the complete specifications posted – the cat is now irreversibly out of the bag.
The Core i9-12900KS, where the S stands for Special Edition, pushes the standard 12900K to new frequency highs. The processor is in an 8P+8E configuration, with the key data points being the 5.5 GHz Turbo frequency across two cores, and 5.2 GHz Turbo frequency across all cores – and like the other K parts, with sufficient cooling this chip has an unlimited turbo period. Given the extreme clockspeeds, this is going to be a ‘thin-bin’ part, which means that Intel is going to need to do extra binning to bring these processors to market in sufficient quantities with the characteristics determined by the bin.

Compared to the regular Core i9-12900K, this new processor adds +100 MHz on the E-core and P-core all-core turbo frequencies, but +300 MHz on the top turbo. Meanwhile base clockspeeds are going up slightly as well, to 2.5Ghz for the E-cores and 3.4GHz on the P-cores – though given the high-end nature of the chip, the 12900KS is unlikely to spend much (if any) time not deep into turbo.
TDPs have also gone up slightly to support the higher clockspeeds; while Turbo power remains at 241 W, base power is now 150 W, up from 125W for the normal 12900K. Rounding out the package is support for DDR4-3200 and DDR5-4800, and integrated UHD 770 graphics.
Intel has launched ‘Special Edition’ models before. The most recent was the Core i9-9900KS, an updated version of the i9-9900K. The KS was the first model to have 5.0 GHz across all eight cores, however supply was limited and it was hard to get hold of. Though in our conversations with the company, we’ve learned that the goal of the 12900KS is to be more available than previous editions. It’s still a super small part of Intel’s overall Alder Lake offering (we’re hearing it’s a sub 1% of all chips can achieve Intel’s metrics for it), but the internal goal at least is to make sure it’s on more shelves this time.
Some of the 12900KS details were leaked even before today's quasi-launch, with some commentary about how this extra frequency is readily available on the standard 12900K with a little overclocking. The difference here is the guarantee of that frequency without needing to overclock – the same argument as it was before with the 9900KS vs 9900K. To a number of users, that’s a useful guarantee to have, especially with pre-built systems and system integrators.
Intel’s main competition comes in the form of two AMD processors. For overall multithreaded throughput, the existing 16-core Ryzen 9 5950X remains AMD's top chip. Meanwhile on the gaming front, competition comes from AMD’s forthcoming Ryzen 7 5800X3D, which is an 8 core processor with an extra 64 MB of L3 cache to help with gaming. AMD is claiming +15% gaming performance over the Ryzen 9 5900X, and 0.98x to 1.2x over the 12900K at 1080p High settings, so it will be interesting to see how they compare. Neither Intel nor AMD have access to each other’s chips right now, so a direct comparison using both sets of data is likely to be inconclusive right now.
|Top Tier Processor Options|
With street pricing on Intel's existing i9-12900K already running at about $610, Intel has upped the ante even further on pricing for the new special edition chip. Officially, Intel is listing the i9-12900KS at $739, and this is almost certainly the company's usual 1000 unit bulk price. Newegg's early listing, on the other hand, was for $799. And while pricing is subject to change (with high-end products it's often decided at the last minute), Newegg's initial price is likely to be at or near the final retail price of the chip once it is released.
Assuming for the moment that Newegg's price is accurate, the $799 price tag represents a further $189 premium for the higher-clocked chip. Suffice it to say, Intel isn't intending this to be a bargain chip, but rather is charging an additional premium for the chart-topping clockspeeds.
What is interesting for gamers is that while Intel has decided to turbo-charge its high-end processor, AMD beefed up one of its mid-range instead. Which means there's a pretty significant price disparity here, reflecting the fact that Intel's top gaming chip is also their top chip for overall multithreaded processing. So depending how performance plays out, Intel may pull off a win here in gaming, but it probably won't do much to move the market share (or dissuade 5800X3D buyers).
It should be pointed out that based on our research, the 12900KS is not a reactionary measure to the AMD chip. AnandTech has seen documents showing that the KS was part of the processor list during Alder Lake development, but has required extra time to mature and finalize – so much so that we wrote up a version of today's article months in advance, expecting an earlier announcement/release date. So Intel's plans up to now have been in flux, and while the company is certainly not above raining on AMD's parade, they also have other ambitions with their 16 core heterogeneous processor.
At the time of writing it's not clear when the i9-12900KS will be formally released. Newegg's early posting had a "first available" date of March 10th, so it may be someone was off by a month there (Update: Intel has announced an April 5th launch date). But we can’t wait to get these chips in for testing.

ikjadoon - Friday, March 25, 2022 - linkIntel is always at the worst part of the performance-power curve. The lines are essentially straight, even straight from Intel themselves:
Intel hasn't focused on a wide, low-power architecture and, boy, does it show. CPUs were never really meant to boost past 4 GHz; everything else is just mountains of wattage for a minor performance bump.
bwj - Friday, March 25, 2022 - linkIt sounds to me like you should check the way your cooler is mounted. I'm using a Noctua air cooler and it takes creative thinking for me to get core temps above 80C, and it takes about a full minute to get them there.
Alistair - Friday, March 25, 2022 - linkI thought Corsair got in trouble as their coolers don't actually mount right with the LGA 1700 adapter. You need a different cooler. I don't hit 100 degrees with a Noctua U12A for example.
Kvaern1 - Sunday, March 27, 2022 - linkI think your issue may be that the default settings are NOT Intel's defaults but the motherboard manufactures crazily overpowered and slightly overclocked defaults.
Case in point the default settings on my Asus board with a 12700KF/Noctua NH-D15 will easily make it hit 100c @ 4700Mhz (Default Asus OC) in Handbrake. Using my own powerprofile it runs 20c cooler @ 4900Mhz.
Hulk - Friday, March 25, 2022 - linkSame base clocks and higher TDP. Interesting. I guess the higher frequency part has greater leakage.
PeachNCream - Friday, March 25, 2022 - linkTypo alert - "The major PC parts retailer listed the uannounced Intel chip for sale..."
Should be "unannounced"?
Ryan Smith - Friday, March 25, 2022 - linkThanks!

IMO, AMD could probably just overclock a nicely-binned i9-12900K.
I can't quite tell for even the released ADL CPUs: what is the all-P-core boost? Is that also 5.5 GHz here? No, right?
