Really very good!
It doesn't lag anywhere, great job by Intel!
As for temperatures, I'm not talking... with Be Quiet Pure Rock 2 ~25-30 C while browsing.
In heavy gaming, it barely reaches 45 C after many hours.
For rendering, I think they have made a huge leap! It works much faster and efficiently even with 2 cores missing.

When the 10900K outperforms the 11900K in almost everything, you can't call it an achievement.... but rather a tragedy or comedy.... Let's not forget that the "new" 11900K has 2 LESS CORES than the "old" 10900K... https://www.youtube.com/watch?v=mxiuvQPL_qs

With the 11600K, maybe your money would have made more sense in the sense that they approach what you really get.

I have it with z590 asus tuf and rtx 3060 minimal difference in games max 5-7 fps from the 10900k I had.
Temperatures are very high, which is a bit strange because I have 19 fans in the case and multitasking is negative (also, in turboboost it draws 250w, even if it were a threadripper).
I had more fps with the 10900k when I had Spotify and a browser open in the background.
In no case is it worth its current price, wait a month for it to drop at least.

From old fanboys.......New generation intel like z590 motherboards. I paired it with msi z590 godlike and nzxt z73. Firstly, compared to the 10th generation, it definitely has much better integrated graphics, which is useless for most of us. Unfortunately, it has 8 cores compared to the 10th generation's 10 cores, which may bother some people, but for gaming, you don't need many cores. Now, in combination with asus strix 3090 oc, there is not much difference compared to the 10th generation (for example, in warzone, there was a difference of maximum 5 fps on max settings). It just supports pcie 4.0 (you combine it with a graphics card, motherboard, and nvme pcie 4.0) which again, the speeds compared to pcie 3.0 are approximately 4% higher, you barely notice it. As a long-time user of many intel processors, I have to say that they are not interested in surpassing amd in performance, they are simply interested in us buying their products just for the brand. Despite all this, it is a power-hungry processor, great for overclocking, perfect for gaming, amazing temperatures with a good liquid cooling, lightning-fast in everything, and very expensive, which is logical since they just released. 10 out of 10 for the 11900k from me, and hoping that the next generation surpasses every intel and amd processor.
