It appears that the specifications for Intel’s first desktop 10nm CPUs may have leaked online. To be more precise, we’re talking about the specs of the Core i9-12900K, Core i7-12700K, and Core i5-12600K.
As Videocardz notes:
“The Core i9-12900K, the flagship SKU of the upcoming series is to features 8 big cores and 8 small cores. The small cores are to boost up to 3.9 GHz (3.7 GHz all-core), while big cores will boost up to 5.3 GHz (5.0 GHz all-core). This SKU is to feature 30MB of L3 Cache.
The i7-12700K is to offer 8 big cores and 4 small cores, which will see 100 MHz lower frequencies, while big cores will see a 300 MHz decrease in comparison to the flagship SKU. A 25MB L3 Cache is to be used by this processor.
The only Core i5 part revealed in this leak is the i5-12600K supposedly featuring a 6C+4c configuration with a small-core boost up to 3.6 GHz and a big core boost up to 4.9 GHz.”
What this basically means is that the Intel Core i9-12900K will feature 16 CPU cores. However, not all of these cores will operate at the same frequency. Furthermore, it seems that only the big cores will support Hyper-Threading (which explains why the high-end model has 16 CPU cores but only supports 24 threads).
Thus, and if these specs are legit, it will be interesting to see how games will run on these CPUs. It will also be interesting to see how hot these chips will run. After all, the Rocket Lake CPUs are notorious for their really high temperatures.
Intel plans to release these CPUs at the end of 2021, though there isn’t yet any specific ETA on when they will come out!

I really don’t see how these little cores help on performance desktops. Intel has to be able to show good gaming performance or nobody will buy these chips. The current self build market is completely taken over by AMD for a reason. Even our office pc workstations all have 16 core Ryzen chips since it boosts productivity a lot.
This seems more like a sidestep then Intel actually trying to compete with AMD.
Hey,
Did Metal Messiah leave the team?
Yea I’ve been wondering this for a while now. Quality of this page has been going down
Unfortunately, and sadly yes. He left because of John’s behavior/treatment. He left of his own accord though. I emailed him long back btw, so I know about this.
His articles were totally professional though so to speak. So no doubt on this.
That’s a shame, really liked the guy – A good influence among the toxis/clueless
Sad new, thanks
Wish him the best
Behavior? Like what?
Wow 10nm, so 2015…
Intel’s 10nm is not the same as TSMC’s 10nm was. Hard to say how comparable they will be.
So much deceptive marketing. On paper the i9 looks impressive. 16 cores, 5.3ghz boost. In reality you’re getting an average 4.4ghz on all cores and it’ll probably burn a hole in your PC while doing it.
What? it says in the article that 12900K has all core boost of 5Ghz and 12700K 4.7Ghz
What deceptive?
When the time comes and CCP takes Taiwan it will be total disaster for the west since we don’t have any noteworthy chip maker except Intel.
Imagine if Intel stops making their own ones like people have been suggesting lol
I’m sure ccp will continue to trade with the west like they are now. just with some extra backdoors installed.
maybe.
Yep. Imo being self-sufficient is the most important thing to aim for.
I really really don’t like TDP of the modern CPUs.
TDB is just a number. I would say the tdp the 5950 of mine for instance is rated to low… ie it wont get the space it needs to breath. While on the other side the rest should not have to pay premium on motherboard/cooling etc to allow such insane core count. Mosy is fine with 8C16T for the foreseeable future.
And in later news… windows 10/11 schedulers with a ton of games/software ran into issues with little.big!
If this is true then Intel’s TDPs are still absolutely absurd for a CPU. So much for a 10nm prices improvement.
I believe it when i see it. Hope the early results are true thoo. Single thread are no matter what peeps say really important especially in for instance thread bottlenecked api’s. My 5950x i usually caped by a single thread in 95% of gaming scenarios for instance.
would this be the most powerful and the most expensive processor?
