A new leak first revealed the Intel processor series for Alder Lake-P laptops, which will hit the Chromebook and laptop market at CES in 2022.

There are several leaks on Intel's upcoming Alder Lake platform. But most of the leaks and rumors are related to desktop computers.

A new Coreboot patch reveals the power limits of multiple Alder Lake-P chips.

This patch clarifies the limits of PL1, PL2, and PL4, each of which defines a different performance that a processor can perform under certain conditions.

PL1 stands for the performance a processor can take, which is the performance of a mobile processor you typically see.

Here are the PL1 odds for Alder Lake-P:

2 + 8 cores: 15 W
4 + 8 cores: 28 W
6 + 8 cores: 45 watts

Like the desktop series, the Alder Lake-P-Chip uses a hybrid design that combines high-performance cores with high-efficiency cores.

Not all processors currently have names. According to the above list, a 45W chip has 6 high-performance cores and 8 high-performance cores.

These are the standard performance limits for Alder Lake P-Chips. Good thing it can still be changed before it's released.

According to VideoCardz, Google's Brya Chromebook platform uses slightly different numbers. The constant power number is the same. However, Chromebooks don't use as much power via PL2 and PL4 (both are temporary power limits).

Brya is the Google Verification platform for the future Alder Lake team. Since December 2020, Google has been using the platform to ensure that the next set of chipsets will work in Chromebooks. There are rumors on the Google platform that the 15W chip will drop to 3W when idle.

The base boot update also makes it appear as a dual-SIM Alder Lake M, which should be for tablets and low-powered devices. According to the PL1 update, the output of the Alder Lake M 2 + 8 core chip is 9 watts.

PL4 represents the peak power consumption of the processor and should not exceed a few milliseconds. At peak times, Alder Lake P chips can use up to 215 watts of power. The output of the Alder Lake M chip can reach 68 watts.

Accordingly, the new chips consume more peak power than Tiger Lake-H. However, the more powerful Alder Lake-P is 20 watts less than the PL2 rating of Tiger Lake-H, indicating that Alder Lake-P is more efficient under normal conditions.
