Although Intel generally indicates a lower TDPS in its processors, the truth is that these are usually the base values well below the real powers used with normal operation of the processor (with Boost and other technologies).
The power values that the processors will have have been leaked Arrow Lake-S, Specifically, the most powerful variants of the K line will be, barring any surprises, the Intel Core Ultra 9 285K and Core Ultra 7 265K.
PL1 mode, which will be identical to PL2 in "performance" modewill reach the not inconsiderable figure of 250W. These values will be even higher in the KS models. In PL4, figures of up to 425 W can be reached, but for very short periods of time in the order of milliseconds. Lower-end models such as the Core Ultra 5 245K will have a PL1/PL2 of 159 W, in this "performance" mode.
PL1 refers to the lower limit of power consumption that is applied if the processor is under low load, while PL2 is the highest limit when the CPU is under heavy loads. Usually the CPU will revert to PL1 mode after being in PL2 for a while to avoid overheating, but if they are set to 250W as is the case with performance mode, they will always have that 250W limit.
These 250W can put more than one heatsink in a bind, so it looks like the default mode will be limited to a more modest amount, and users will have to manually activate performance mode.
It remains to be seen whether the history of the Intel Core Raptor Lake and Raptor Lake Refresh (13th Gen and 14th Gen) will repeat itself and Alder Lake will avoid the degradation and instability problems caused by these high-performance modes.
