By Intels own admission, it uses a lot of power, and barely beats the 5950x with a hosed buggy OS and 100 watts more power (and heat) and they recommend water cooling. Those are not in question. Thats not good news.
But the final decision should be made after Nov 4th, I grant you that.
That's why I'm a bit ehh on the top tier. To be fair I also thought the 10900k and 11900k were idiotic units as well. They cost a lot more and offered very little over their i7 counterparts, while also being heat monsters under all core loads.
The 12400 through 12700 range intrigues me though. We have had an absolute dearth of great $200-$250 range options for ages now. AMD bringing out a 5600 non X to meet it at $199 would be sweet.
CPUs often remind me a lot of people arguing over cars lol. Some people are like "well this super special version is way better than brand X super special version", when 90% of people are going to be comparing what they can get that fits a tighter budget.
To be clear I'm not saying you're a part of that, but the level of attention on the 12900K is slightly amusing to me, from people either very excited or very dismissive, but it's probably the least relevant piece of the entire lineup in terms of potential market, volume, or revenue.
