Intel has announced that, starting today, three of their tenth generation core lines are to be retired -- Comet Lake-U, Ice Lake-U and Lakefield.

Volker Risska of ComputerBase first reported that Intel would finish shipping the three product lines by April 2022. Intel's Lakefield series was their first line to utilize Hybrid Technology. Once the Lakefield series is discontinued, consumers will have to wait until Alder Lake for hybrid supporting technology.
