The current generation of Intel processors has the PL2 limit (ie the value of consumption, which should not be permanently exceeded) set to 250-251 watts for the most powerful models. In July, there were reports that it would work Alder Lake in the form of Core i9-12900K could be a little better. Specifically, the PL2 limit of the high-end Core i9-12900K should not be higher than the limit of the mainstream Core i5-12600K: 228 watts.
However, the latest leaked Intel materials are not so optimistic and for performance models they state a value of 241 watts (ie 13 watts more) than previous reports:
It seems that the new production process, officially called Intel 7, which is supposed to indicate a two-generation shift compared to the current 14nm production, practically does not change anything in energy requirements. At the same time 14nm Rocket Lake i „Intel 7“ Alder Lake they have 8 large cores. It can be argued that Alder Lake is still equipped with 8 small cores (Atom), but their consumption is negligible in this context (14nm 12-core Atom C3858 had integrated 16 SATA ports, 8 USB ports, 16 PCIe lines and in short complete integrated equipment TDP 25 watts). It seems that the ~ 250W PL2 that came with the last generations of 14nm processors was not a temporary tax on the missing 10nm process, but rather a trenderm, as the advent of a new process will not return the energy side to the old tracks.
It is worth noting that the materials also contain values for Raptor Lake. He is the successor Alder Lake, which, according to available resources, relies on tightened large cores and twice (16) small cores. He’s coming about a year after Alder Lakewith which it shares the same socket. Motherboards must therefore be dimensioned to suit not only needs Alder Lake, but also Raptor Lake. According to the currently available documentation, it seems that although Raptor Lake will increase PL2 by 12 watts (from 241 to 253 watts, the all-time high on Intel’s desktop), while PL4 (power consumption limit) will decrease from 359 watts to 314 watts. The high PL4 limit has already surprised the mobile models Alder Lake. It seems to be due to the property of large nuclei to produce the high short-term peaks that occur Raptor Lake managed to moderate somewhat (specifically by 45 watts).
