Alongside the Alder Lake-S Desktop lineup, Intel is also readying its Alder Lake-P Laptop CPU lineup which will feature both high-end and mainstream chips. It looks like one of the fastest chips within the lineup has leaked out within Ashes of The Singularity benchmark, the Core i9-12900H.

The Intel Alder Lake-P lineup will be replacing the Tiger Lake-H45, Tiger Lake-H35, & the Tiger Lake-UP3 series, processors. As such, both high-end and mainstream chips fall within the same segment but will be identified with their 'H' and 'U' series naming. It can easily be told that the i9-12900H is a high-end chip and will be one of the fastest laptop CPUs around if not the fastest of all.
