The Radeon RX 7900M is now AMD’s most powerful laptop GPU – AMD

The new mobile GPU is based on the RDNA 3 architecture and is “the first mobile GPU to use microchip architecture.” The company claims that its new mobile GPU is capable of delivering very high frame rates at 1440p resolution instead of 4K resolution, as its goal was to enhance the gaming capabilities of standard PCs.

Combined with an upscaling technology called FSR 3 (FidelityFX Supersolution) which is similar to NVIDIA’s DLSS 3, AMD’s proposal significantly boosts frame rates in games like Starfield and Forspoken.

The Radeon RX 7900M has 72 compute units (when the Radeon RX 7700S has less than half, 32 counts) and has 16GB of GDDR6 RAM that consumes up to 180 watts (significantly more than the 110 watts of the mobile version of NVIDIA’s GeForce RTX 4080 ). AMD claims it can still beat the latter by 7% in average frame rate while providing an additional 4GB of GDDR6 memory. In one example, AMD claims that a PC with its flagship mobile can outperform a laptop with equivalent GeForce RTX 4080 processing power by 27% in Starfield displaying a frame rate of up to 62 fps (using FSR 2, setting Ultra with a resolution of 1440 pixels). In another example, it states that Forspoken can run at 201 fps with FSR 3 enabled (with FSR 3 disabled, the fps number is 63). The company is also claiming higher frame rates for a number of raster games, though it appears to miss out on the majority of games with ray-traced graphics running on NVIDIA GeForce RTX 4080 laptops.

Along with the new mobile GPU, AMD also announced its partnership with Alienware, with the latter offering a version of the m18 laptop with a Ryzen 9 7945HX processor alongside a Radeon RX 7900M. The computer has an 18-inch QHD+ display (2560 x 1600 pixels), up to 64GB memory, etc. Alienware’s Radeon RX 7900M-equipped PC is scheduled to launch in Q4 2023.
