Intel is expected to launch its next-generation Core Ultra 200 "Arrow Lake-S" desktop processors on October 24, 2024, and since these chips introduce the new Socket LGA1851, they launch alongside new motherboards. The first wave of Core Ultra 200 series processors will be "K" or "KF" SKUs targeting gamers and enthusiasts, and the first compatible motherboards will be based on the premium Intel Z890 chipset. Intel is reportedly being extra careful not to repeat the "Raptor Lake" fiasco that saw motherboards power its 13th- and 14th Gen Core "Raptor Lake" processors with elevated voltages, causing their irreversible physical degradation over time. To this effect, Intel is reportedly getting its motherboard partners to ship their Intel Z890 chipset motherboards with Intel Default Power Profile out of the box.
A motherboard-level Power Profile dictates the processor base power (PL1), maximum turbo power (PL2), and IccMax values. We don't know these values for "Arrow Lake-S," particularly its top Core Ultra 9 285K part; but to illustrate what Default Power Profile out of the box means, we have to look at "Raptor Lake-S." For a Core i9-14900K, the Performance Power Profile—which is what Intel Z690 and Z790 motherboards enable out of the box—provide a PL1 of 125 W, PL2 of 253 W, and IccMax of 307 W, which is what Intel considers stock for this processor model.
The Extreme Power Profile, which can be enabled in the UEFI setup program, holds PL1 and PL2 at 250 W, and unlocks 400 W IccMax (something that requires two 8-pin EPS power connectors to be plugged in, each capable of 225 W). The Insane Power Profile, available on select motherboard models, completely unlocks PL1 and PL2 to "4096 W" (i.e. anything that the motherboard VRM is capable of providing), and IccMax to 511 W (the socket's design limit). The Intel Baseline Power Profile (aka Default Power Profile) runs contrary to these three.
On the Core i9-14900K, the Default Power Profile gives the processor a PL1 of 125 W (which is also the chip's base power value), but the PL2 maximum turbo power is limited to 188 W, and the IccMax is capped at 249 W. These severely reduce the processor's boost frequency residency even at stock settings.
If the rumors of Intel getting motherboard vendors to ship Z890 chipset motherboards with Default Power Profile out of the box are true, then out of the box, these processors will likely not perform as Intel intended, and the company's guidelines to reviewers and end-users would be to manually enable at least Performance Power Profile in the UEFI setup, to at least get stock performance out of these processors.
