It's really funny that 12900k consumes 243 watts and the 5600x consumes only 67 watts ....
To achieve such top charts you have to consume almost 3 times more power ... ?
Except productivity 12900k is unimpressive.
I looked in my local shops the cpu's prices are ok inline with the MSRP but big problem are the mainboards.There is a 12600k in stock for 370$ but the cheapest z690 board is 280$ almost the same price as the CPU so .... The board support DDR4
12700K is the one I would pick up. It runs much cooler, and isn't that much slower than the 12900. Not considering the price difference between the two.
The Core i5-12600K is the price/performance king in the Intel Alder Lake lineup. With its competitive pricing of $300, it's a clear winner against AMD's Ryzen 5 5600X and faster than even the 5800X in many applications and games. This is the gaming CPU you want.
With the Core i7-12700K, Intel has released a formidable competitor to AMD's Ryzen 5800X and even 5900X. Thanks to eight powerful Golden Cove cores, the processor handles all workloads very well, including gaming. Compared to the i9-12900K, it runs almost as fast, but much cooler, with better efficiency.
The 12700k is 6% better on average at 1440p and 9% in 1080p ....
No good motherboards at Microcenter so I passed. They only had DDR5 5200 too, and I wanted 5800 or higher. I heard the rock solid OCs are showing up on 5800 and beyond.
One guy has 6800 28-30-30-28 1T on a 12900K and it's insane how fast that 2 stick quad-channel pumps the bandwidth. Latency isn't bad at all, still better than Ryzen.

We compare all the new Intel Z690 chipset based motherboards for Intel's 12th Gen Alder Lake processors, so you can get an overview of which boards are worthy of your consideration and which can be skipped no matter if looking for something basic or a flagship model.
The achile heel of the ADL platform is the motherboard itself
In this not-so-quick look at the upcoming Intel Z690-based motherboards, the thing that stands out is that most of them are overpriced. It might be a bit rude to start the conclusion in such a blunt way, but it's a fact and only made worse by the current graphics card situation. Yes, there's a shortage of all types of components ranging from capacitors to power regulation components, and PCB prices are up as well, but $200 for an entry-level motherboard is a big ask. In all fairness to most motherboard makers, the entry-level boards are actually quite decent overall, but a $40–50 premium over the last generation is a big ask when Intel is only charging an additional US dollar for the Z690 chipset compared to the Z590 and Z490 chipsets.
We'll have to wait and see how pricing settles since there isn't much differentiating the various Z690 motherboards in the same category in terms of feature sets. The rest comes down to personal preference, but the past few pages will have hopefully given you some kind of insight before reviews.

gamers nexus said they weren't able to get a 6000mt kit stable with gear 1 or 2
so they dropped down to a 5200 kit for the review at gear 2
really watch the kitguru video, if you aren't planning on using this as a workstation which is where ddr5 shows it's biggest performance increases, stick with ddr4 if you already have a really good kit.

There is not a single youtuber that is a memory OC guru.
There are guys killing it on Overclock.net ..
If you buy a kit with good IC DDR5, it's faster than DDR4, but none of the good motherboards are DDR4
4400C19 DDR4 really isn't any good either.
Eventually we will see someone run one of these DDR4 god-tier kits with a 12900K and we can compare it to some of the better DDR5 .. fully expect to see the DDR5 kit stomp it.

There is a guy with 3866 C13 and that was probably the best anyone could do with RKL. Apparently, ADL acts more like Comet Lake (high frequency) even with DDR4, so that should be interesting.

Has the above thread been misplaced/renamed/merged/stickied/locked? Well then there's a doins transpirin! Find the tome and bring forth the sacrifice to restore peace and order.
"VIAGRA FALLS, slowly I turned, and step by step, inch by inch, I walked up to him, I smashed him, I hit him, I bonked him, I bopped him, I socked him and I mashed his face and I knocked him down."
What strikes me as odd is that in some games DDR4 is faster and in other DDR5 is substantially faster. I guess maybe it comes down to bandwidth versus latency? Could also be optimization issues, I suppose? With the high price of DDR5 I am not sure it is really justified at the moment.
Overall, I'd say this is a decent release for Intel, and a welcome change from the last few from them. The CPU is faster, in some cases impressively faster. On the other hand, considering it's an entirely new architecture with P and E cores, and finally getting off 14nm+++++, if it was any slower it would be pretty embarrassing. They hit their target, but didn't really blow it away, IMO.
It's not that much faster than Ryzen in a lot of situations, so those already on AM4 platform would probably be best served to wait to see what the 3D cache Ryzen chips can do because I suspect they'll close a lot of the performance deficit that exists, and it's potentially an easier and cheaper upgrade.
Power load doesn't seem to be an issue in gaming just in all core workloads
All core power consumption is pretty insane though. It doesn't seem like a good choice for workstation type tasks. Even in situations where it's slightly faster if you're pulling 50% more power it's not going to be worth it unless every single minute of time is absolutely critical.
So at 1440p and higher what does this get you game performance wise? I don't want 1080p benchies.
Even in 1080P some of the tested games are still GPU bound. If you're not seeing major CPU limitations in the games you play then it's unlikely to be worth it. Overall it's only about 10-15% faster on average than the 11900K even at 1080P so you're not going to see a night and day difference in gaming. I'm sure there are some specific games where it will make a difference but if you're playing those with heavy priority then you'd likely already know.
Well 1450 bucks is a bit much for only board, processor and ram. Also every review has said that if you are in a 5000 series and especially 5900x or 5950x then it is not worth the upgrade right now. So in this spirit I am cancelling my orders.
Also the full order wasn’t what I wanted.
I wanted an ASUS Strix E but got an F.
I wanted a 12900K but got a 12900KF.
I wanted a 5200 C36 Trident Z ram or better but got a non RGB XPG 5200 C38 ram.
So will need to wait till mid next year for my next chance to order.
The E-cores seem very effective (around 5W vs around 50W e vs p), just saw the Anandtech graphs showing watt consumption between different core loads. It's almost like core execution order in W10 is p, p HT, then e instead of p, e then p HT?
