AMD has unveiled the Radeon RX 7900M mobile GPU built around its RDNA 3 architecture, its fastest mobile gaming chip to date and "first-even chiplet laptop graphics." The company has positioned the new chips for high FPS 1440p (QHD) gaming rather than 4K as a way to boost regular laptop gaming. AMD is also touting its FSR 3 (FidelityFX Super Resolution) upscaling tech that's similar to NVIDIA's DLSS 3, promising a large boost in frame rates for games like Starfield and Forspoken.
As a flagship chip, the RX 7900M comes with 72 compute units (compared to 32 for the RX 7700S) and features 16GB of GDDR6 RAM, while consuming up to 180 watts — well beyond the 110 watt TDP of NVIDIA's RTX 4080 mobile chip. AMD claims it can outperform the latter by 7 percent on average in terms of frame rates, while offering an additional 4GB of GDDR6 RAM.

In one example, AMD claimed it could beat a laptop with an RTX 4080 mobile chip by 27 percent on Starfield with a 62 fps frame rate (FSR 2, Ultra 1440p). In another, it said that Forspoken could run at 201 fps with FSR 3 turned on, compared to 63 fps with the setting disabled. It also listed higher frame rates for a number of rasterized games, though it was beaten by a majority ray-traced games run on NVIDIA RTX 4080 GPU-equipped laptops. This is an issue we flagged after reviewing the Radeon RX 7900 XTX and 7900 XT desktop processors last year.
Along with the mobile GPU, AMD announced a partnership with Alienware, integrating its RX 7900M and Ryzen 9 7945HX processor into the m18 laptop. Along with those chips, that model comes with an 18-inch QHD+ (2,560 x 1,600) display, up to 64GB of RAM, 8.5GB of storage max, and more. That model, along with the RX 7900M, is set to arrive in Q4 2023, when we can hopefully put AMD's claims to the test.
