AMD is likely to offer a slew of Navi mobile GPUs with a sub-100 W TGP (total graphics power) early next year. These GPUs are expected to be based on Navi 23 and Navi 24, which are, in fact, yet to be announced for desktops. This information comes from known leaker Patrick Schur, who has detailed the TGP targets for Navi 23 and Navi 24-based Radeon 6000 GPUs.
According to Schur, there are three Navi 23 mobile variants on the anvil and they will have TGP targets of 65 W, 80 W, and 90 W. It may be noted that we are taking about the TGP here, which is a measure for total power consumed by the entire graphics board and is different from the GPU die's TDP.
Assuming that the Navi 22 series for desktops will use a 6700 nomenclature, Navi 23 could use 6600, 6500, and 6400 names depending on the TGP. Navi 23 will succeed the Radeon RX 5700M with VRAM at or above 8 GB and clocks around the 2 GHz mark.
Schur is also attesting to a Navi 24 series in the works. There could be two Navi 24 mobile variants — a Navi 24 XM with a configurable TGP of 35 W, 42.5 W, and 50 W, and a Navi 24 XML with a very low TGP of 25 W. It is likely that these Navi 24 chips will succeed the current Radeon RX 5500M and RX 5300M, respectively. Navi 24 variants are also being speculated to offer 8 and 6 GB GDDR6 VRAM for the XM and XML variants, respectively.
Upcoming laptops SKUs in 2021 can be expected to be a healthy mix of Navi RDNA2 mobile and NVIDIA Ampere mobile variants. What is not clear right now is whether a Ryzen 5000 APU and Navi RDNA2 mobile combination will feature some sort of Smart Access Memory implementation similar to what we are seeing on the desktop side.
AMD Radeon RX 6000M GPUs based on Navi RDNA2 mobile are expected to be announced during CES 2021.
