AMD seems to be testing several RDNA 2 based Radeon RX 6000M mobility GPUs internally and early information on a Navi 23 and Navi 24 discrete chips for the laptop segment has leaked out. Reports by Twitter insider and leaker, Patrick Schur, AMD is working on several mobility SKUs based on the Navi 23 & Navi 24 line of GPUs.

According to Patrick, AMD has several SKUs in the work for its Radeon RX 6000M family. It looks like AMD will initially be introducing mainstream and entry-level variants based on the Navi 23 and Navi 24 GPU design. The Navi 23 and Navi 24 GPUs haven't seen a desktop release yet. The upcoming RX 6700 series will be making use of the Navi 22 GPUs so we are looking at the Radeon RX 6600, 6500 & 6400 series cards based on the naming convention.
