We have some evidence to predict the power consumption of Alder lake-P. Some of them are listed below
a. Chinese youtuber 'geekerwan' reports a Cinebench R23 score of 14288 when 12900K is limited to 35W. According to him, eight E-Cores will score 7336 at 17.3W.
b. A Japanese Twitter user reports that in the best of several measurements, the Cinebench R15 score is 1845 when the 12600K is limited to 45W, and 1102 at 15W. This is a realistic hint to predict the performance of the i7-12650H.
c. For processes that are less demanding than gaming, Alder lake consumes less power than its Ryzen competitors. In other words, it records better performance-per-Watts.
d. On Tiger lake, the lower limit of cTDP was shown as the nominal TDP; on Alder lake, the upper limit of cTDP is often shown as the nominal TDP.
Based on these information, it is very likely that at least some of the leaked information that this site has been dealing with so far was achieved with power consumption as per nominal TDP, at least the Cinebench results.
