Intel Core i9-12900KS Listed at $791 with 150W Processor Base Power
Intel recently announced the Core i9-12900KS, its new flagship desktop processor that comes as a deterrent to the AMD Ryzen 7 5800X3D, which the red-team claimed to be matching the current i9-12900K in gaming performance. The new i9-12900KS is built from the highest bins of the "Alder Lake-S" C0 silicon, which are needed to support the chip's 5.50 GHz maximum Turbo Boost frequency on the P-cores, and 3.90 GHz max Turbo on the E-cores. While the E-core max Turbo isn't any different from the i9-12900K, the P-core sees it go up from 5.20 GHz on the older model.
The Core i9-12900KS processor is now beginning to show up on retailers, with Shop BLT listing it at USD $791 for the boxed retail processor, and $780 for the chip-only OEM part. Even at these prices, the premium over the i9-12900K is barely $150. The listing also sheds light on increased power limits. The processor base power value for the i9-12900KS is set at 150 W, compared to 125 W on the i9-12900K. This isn't the same as PL1, as Intel changed the definition of its power definitions with the 12th Gen. The maximum turbo power value (PL2) remains unknown. For the i9-12900K, this is set at 241 W. This isn't the first "KS" SKU by Intel, with the last one, the i9-9900KS, shipping as the first processor with a 5.00 GHz all-core Turbo frequency. It remains to be seen if all Socket LGA1700 motherboards support the i9-12900KS with a firmware update, because not all 300-series chipset motherboards supported the i9-9900KS due to its steep electrical requirements.

And by the way
Surely we aren't pissing into the wind,
Because you caught them with your face and reply every single comment we made.
i await your reply as you also can't help but reply to me :)
Anyway enough discussing when you are just trolling me now. bye /ignore
I guess you do realize logic isn't on your side.
I didnt find any direct comparisons here on TPU about gaming vs power consumption except the 12900K. @W1zzard any reason for that? Gaming comparison is valuable info I'd say.
BTW.
Is Hybrid arch an improvement? It is an improvement but.
Intel did the e cores to have more cores available and that (in my opinion) is due to Intel being unable to get more P cores in there to tackle the core count with AMD counterparts. Kinda marketing scheme to be fair.
Ecores dont have hyperthreading Pcores does but you can fit more ecores since these are smaller. I think 1 pcore is equivalent to 1.5 Ecore in size. Correct me if I'm wrong.
So improvement is there but i can bet it would have been better if you replaced Ecores with Pcores. I think, it would have been better for Intel to put more Pcores instead of Ecores. As you know, Pcores are much faster and have HT but the core count would have been lowered significantly and from the marketing perspective would not look as good with lower core count in comparison to AMD's offerings. The other aspect is power consumption. Ecores use less power than Pcores and thus makes them efficient by a significant margin.
Is it an improvement? You get more cores so in a way it is. Is it the right direction for the improvement? You can argue here if you think strictly about performance.
So when you say your 12700K is better than CPUs without ecores sure you are right but if you had the choice to have a 12700K without Ecores but instead you would get more Pcores, which one would you pick? 12700K as it is now or 12700K with, lets say, 2 more Pcores instead Ecores?
Also, from a manufacturing side, Ecores are smaller so easier to make them instead of just Pcores. But that is relative.
At least, that is just what I think. I dont doubt people have different point of view.
with Windows 11 there is a little regression disabling E-cores while gaming.
I dont care about random reddit users... ok now everything is more clear to me.
You settled for an inferior CPU and now your are claiming E cores are useless.
Great for you. It is not a point of view.
it is a matter of fact confirmed by someone who owns 12700K, 5900X and 5800X in my house
and by the way Igorslab already compared gaming power consumption of those CPUs:
12700K is far more efficient than 5800X.
My tests at home absolutely confirmed what Igorslab reported (actually in Far Cry 6 I have a lower power usage, but I'm playing at 1440P, so it is normal).
I don't know why people are in denial here. Maybe too many years of Intel 14++++++ .... it sounds like sour grapes to me... ;)
You asked, I delivered, but where is your follow-up ?
He did series of studies for P-cores and Error-cores
Those Error-cores are like the shortest plank of the barrel.
When they are enabled, your poor CPU have to downclock its components to match them, thus hindering performance.
Although they are called "Efficient cores" but they are not that efficient and eats up the power budget which could translate to more P-core performance if correctly ultilized.
Not to mention the totally unnecessary scheduler introduces compatibility problems.
There are reasons why Intel themselves chose to retain a pure P-core design in their Sapphire Rapids lineup.
They certainly knew their hybrid architecture would be disaster for any mission critical applications.
The articles about E cores performance are here in Techpowerup website, and I trust this website very much.
www.techpowerup.com/review/alder-lake-windows-10-performance/
sure, software and scheduler has to be improved, and it is happening over the time.
Did you watch the deep analysis?
Do you know what components in your CPU will be downclocked when error cores are enabled ?
Do you know how much the error cores are affecting your CPU's interconnect speed, and IMC frequency ?
The problem is there, blindfolded yourself won't solve the problem.
Keep calling them "error cores" because you don't have it, doesn't make your point valid.
On Windows 11 a 12900K with E cores enabled is 1.2% FASTER than with E cores disabled.
And I see you are unable to understand our argument.
My first reply in the post already stated I want more P cores over the Error cores.
Each Error core cluster could fit at least one P core
So the "Pure P core CPU" would always have 2 more P cores than the hybrid ones.
That basically means a 12900k/12700k with Error cores disable vs a 12600k
The "Pure P core CPU" will always have 25-33% more P-cores, Higher boost clocks, faster interconnects, able to run higher frequency memory, and no compatibility issues.
That will certainly be a win of the "Pure P core CPU".
(Edit: by the time of the 13th gen, Intel would double the amount of Error cores
Since the die area is around 1.5x for a cluster vs P-core, 4 cluster = 6 P-cores
So the "Pure P core CPU" would have 75-100% more P-cores if the die spaces are fully utilized,
But all is lost when they decided to go the Error core route)
That's why I suggested you to watch Buildzoid, He deep tested everything and listed every calculations he did.
Yet you are still blindfolded, only comparing Error cores on vs off , obviously you really don't understand.
If we draw a line at the PL2 of the 12900k ~240W , a 8+8 CPU will have better MT benchmark performance vs a theoretical 10 P-core CPU (5~8%)
However is that worth all the trouble caused by the hybrid design and windows 11?
Personally I think not.
I'm gonna have to check my 5800x with Horizon Zero Dawn what it will show. I have the 6900xt so it will be apples to apples.
I saw this happening in any Windows new release :rolleyes:
Windows 11 is just fine and it is improving update after update. in some games is like that, in the other the 12700K is using more... it could just be better silicon in the 12700K in that specific case.
BTW the point was the efficiency of Alder Lake. I checked my 5800X in APEX Legends, a game I have on both PCs, and it's using 5 to 10W more than my 12700K, on average. PC world is not only benchmarks and gaming.
E-cores has a relevant impact on performance in many applications:
THIS website did an extensive analysis about that, but I think it is easier to just look at Buildzoid ranting on an Youtube video, right ?
For a "professional overclocker" computer usage is just running a benchmark.
For me it is something different.
Nice sentence, but do you really understand ?
Backwards compatibility is the most important factor in x86
Being an hybrid architecture and relying on the beta testing windows platform automatically fails in any mission critical applications.
I've mention this in previous reply but clearly you didn't read.
There are reasons why Intel themselves retain "Pure P core" structure in Sapphire Rapids.
Because no one would consider a beta testing hybrid architecture in production environment.
No one would risk a chance of important applications being randomly thrown into Error cores and suffer performance penalty (or simply crash due to incomplete instruction set)
I am sorry but you simply don't understand.
These hybrid CPUs are exactly the opposite of your sentence.
They can't be trusted to do anything critical besides benchmarks and gaming.
They are nice, but not trust worthy and has to be babysit in order to function "normally".
As for buildzoid,
Once again,
Did you watch that video I posted up there?
Did you find anything "incorrect" in that video?
Can you prove that his data is "wrong" / "not trust worthy" / "just ranting" ?
If not, then his analysis on P+E cores should be considered "correct" and you should listen.
A lot of people are using Alder Lake in production environment, me included. again, baseless assumptions.
Alder Lake works without any babysitting. Just using the right operative system.
Now, your turn, time to prove your baseless assumptions,
Please tell me WHO are using Alder Lake Hybrid CPUs in "Production environment" when Alder Lake Xeon W NOT YET existed in the market.
Please don't tell me throwing a 12900k into a typical Z690 MB is a "Production Environment".
Do you really know what's a "Production Environment" ?
Also, you still misunderstood what I said.
Not all Alder Lake CPUs need babysitting, just the Hybrid ones.
And again and again,
Did you watch the video up there?
Find anything "incorrect" ?
If you don't , then my "assumptions" aren't "baseless"
