Intel Alder Lake-P mobile processors could be very power hungry, leaks suggest

A new report has revealed the PL values of the upcoming Alder Lake-P and Alder Lake-M mobile processor architecture. While Alder Lake-M comes with rather conservative values maxing at 30W, Alder Lake-P goes well beyond that, reaching up to 115W.

Intel’s hybrid processor architecture should be more efficient as it’s based on a smaller node, but PL values will apparently increase slightly. According to Coelcanth’s Dream (via @davidneco25320), there will be three variants of Alder Lake-P CPUs divided by TDP: 15W, 28W, and 45W.

The 15W and 28W variants should be Alder Lake-U, which come with 2x (15W) or 4x (28W) big cores and 8 small cores. As for the 45W variant, it likely is Alder Lake-H, packing 6x big cores and 8x small cores. As for the PL values, the 15W variant has a PL2 of 55W and the 28W variant a 64W PL2. Lastly, here’s the 45W variant, sporting a 115W PL2 value.

The report also included the PL values for Alder Lake-M. PL1 is set at 9W, while PL2 is 30W. The core configuration of these processors will be the same as the 15W variant of Alder Lake-U, featuring 2x big cores and 8x small cores.

All Alder Lake-P and Alder Lake-M variants seem to feature the same iGPU, which is expected to come with 96 EUs, which should be double the number of EUs in the desktop Alder Lake iGPU.

KitGuru says: If these CPUs ship with these PLs, it will be hard for a laptop cooling system to handle. Most premium gaming laptops might be able to, but mainstream and entry-level laptops will probably have to throttle the CPU down to keep temperatures in check.
