Retail Version of Intel Alder Lake Core i9-12900K Overclocked to 5.2 GHz on All Cores
Although we can't confirm it, the screenshot below is said to be of a retail version of the Intel Alder Lake Core i9-12900K that has been overclocked to 5.2 GHz on all P-cores, with the E-cores at stock clocks. It is said to be drawing a massive 330 Watts at these clock speeds, which is rather a lot for a consumer level CPU.
Sadly details such as the motherboard used and RAM clocks are absent. The E-cores are said to be locked at a maximum clock of 3.7 GHz, so there appears to be no overclocking potential in them. Yes, Intel does manage to edge out AMD's Ryzen 9 5950X at these clock speeds in the multithreaded test, which is no mean feat considering we're looking at eight threads less here, but Intel does so at over twice the power draw.
Update: Updated due to a slight misunderstanding, the E-cores were apparently enabled, but running at stock clock.

My guesses are:
1. With Win11 = barely usable, with Win10 = Disaster
2. With DDR5 = Wins in productivity but lose in gaming due to high latency
3. With DDR4 = Ties with Zen3/11th in gaming, lose in productivity.
4. Power consumption = fallout fusion cells
For example, i've seen some cinebench runs on a 5950x with LN2 running at 6+ ghz. It probably consumes over 500watt at that frequency. Does that mean it's a bad CPU that consumes a lot of power? Nope. So it's the exactm same with the 12900k, only difference is you don't need exotic cooling, you can do it in your house.Nobody said anything about idle. Running blender a 10900k at stock beats the 5800x at stock while being 30-35C degrees COOLER. You can see it in the review from this very site ;)
Total System Power 5990x OC = 332W
intel Fanboys = BUT AMD DRAWS A LOT OF POWER TOO YOU KNOW
wtf
I doubt I'll bother with this release
A) boards will be stupid priced just like z590 boards are
B) 12900k will also be way too much at launch
But I contacted optimus and asked if they had a mounting bracket for socket 1700
They said prior foundation and sigV2 water blocks are compatible, which I find hard to believe but okay :cool:
I was considering a Noctua nh-d15 in a high airflow case.
Do you think it will be significantly different than a 5900X?
