AMD is planning a high-end RDNA 3 GPU for its Radeon RX 7000M mobility lineup which could utilize its flagship Navi 31 chip.
AMD To Debut A High-End RDNA 3 "Navi 31" GPU In Its Radeon RX 7000M Mobility Lineup
Golden Pig Upgrade at Bilibili discloses that the cut-down Navi 31 GPU could be utilized for laptops. While the news of this move had been revolving, we now know how Navi 31 can enter onto laptops. The desktop Radeon RX 7900 GRE, released almost a month ago, features the Navi 31 XL variant, a cut-down of the original high-end RDNA 3 GPU.
The RX 7900 GRE will be crammed into a laptop.
It means that the navi31 core packaged in a compact 256b package will be stuffed into a notebook, and the actual specification may be higher than GRE.

While specific details aren't certain yet, Golden Pig Upgrade suggests that the "expected" Navi 31 laptop GPU could boast a higher performance than the Radeon RX 7900 GRE, with a design that's not as much cut-down as the GRE variant but features a 256-bit memory interface onboard. AMD's approach is unknown here, but the company will have to tune power consumption and base clocks aggressively to provide higher performance. The more compact (40x40mm) design will also allow for laptop compatibility with the new Radeon RX 7000M high-end chips.
This new GPU is to be featured in the Radeon RX 7000M lineup which has so far only received Navi 33 GPU SKUs with Navi 32 and Navi 31 missing from the action. The company will soon be releasing its first Navi 32 offerings for desktop PCs so we can expect a mobility launch around the same time. It looks like these variants will compete well with NVIDIA's RTX 4080 and RTX 4070 series GPUs on the mobility side.
What we have seen so far of the AMD RDNA 3 family is that the company is missed out on some major segments on both the desktop and mobile front. The Radeon RX 7000 desktop lineup has only covered the ultra-enthusiast market for now with only the RX 7600 for entry-level gamers & the mobility Radeon RX 7000M side has only received entry-level Navi 33 SKUs covering the RX 7700 and RX 7600 series. Meanwhile, NVIDIA is covering all market segments with its RTX 40 Ada lineup with only the sub-$150-$250 US market missing the action which is likely to be fulfilled with an RTX 4050 release.
