Intel’s next-gen Arrow Lake-S desktop processors will reportedly come with higher power limits than preceding Alder and Raptor Lake offerings. The top-end Core Ultra 9 285K (Core i9-15900K) will retain its predecessor’s “PL2” boost power limits when using the Baseline or Performance profiles. However, the Extreme power profile, exclusive to the 24-core CPU, will allow a boost power “PL2” consumption of up to 295W (up from 253W on the 13900K/14900K).
The boost power consumption of the Core Ultra 7 265K (i7-15700K) and the Core Ultra 5 245K (i5-15600K) have reduced by up to 18W and 29W in the baseline and performance profiles, respectively (via Elchapuzasinformatico). This follows Intel’s decision to relax the maximum voltages for its failing 13th and 14th Gen processors.

Intel’s latest microcode update (still being rolled out) reduces the maximum core voltage of the Core i9-13900K and 14900K by 0.16v. As a side-effect, the boost clocks on the latter have been reduced to 5.785 GHz (70C) and 5.631 GHz (105C), respectively. Previously, it would boost up to 5.8 GHz under such conditions at the cost of increased thermals and voltages.
The Core i7-14700K and i5-14600K have been curbed in a similar but lighter fashion. The 14700K now tops out at 1.52v (<-1.55v), while the 14600K achieves a peak voltage of 1.5v (<-1.59). Their lower power requirements mean that their boost clocks are similar, even under heavy temperature loads (via Golem).
Additional rumors about the Arrow Lake-S desktop family claim an 8-core budget SKU, up from the previous 4-core designs. According to @OneRaichu, the Core Ultra 3 205/215 (Core i3) will feature 8 cores, including 4 P and 4 E-cores. This would pressure AMD to release new Ryzen 3 processors, the last of which was the Ryzen 3 3300X/3100.
Arrow Lake-S is expected to launch this fall (or winter) alongside the new LGA1851 socket. Only the three K-series processors are expected to debut this year, with the 65W non-K and mobility SKUs planned for early 2025. You can read more about the Arrow Lake-S family here.
