We all noticed it, the Chinese do not respect the NDA. So that’s where the new leak comes from, very precise concerning the performances of the Intel Core i9-12900K but also the Core i7-12700K and the Core i5-12600K. 
The bench used is Cinebench R20 and the previously listed processors were tested on a pre-assembled desktop computer, the Lenovo Legion 9000K.
i9-12900K: 241W and 36% gain
What’s at stake here is the impact of PL2 mode (PL2 / 241W max power consumption) on performance. According to this test, using this mode the 12900K is 36% faster than with its base frequencies (PL1 / TDP of 125W). Concerning the Core i7-12700K, the difference is 30% and using PL2 on the Core i5-12600K gives it a “only” 10% boost. Of course, as we have already written, some people will be frightened by the power consumption of the 12900K when using the PL2 mode. In this case we are talking about almost doubling the power consumption to get a 36% performance improvement. However, anyone who has overclocked their CPU knows that these figures are logical, even more so with Intel, which ensures high frequencies and has a relatively good command of the dissipation of its processors. As you can see, with the right cooling system, Alder Lake processors seem to promise a really interesting performance potential.
