AMD revealed the Radeon RX 7900M, its newest top mobile GPU, in an effort to catch up with its competitors. With 16GB of GDDR6 memory, this AMD Radeon graphics card belongs to the top class of mobile gaming GPUs and is part of the RDNA 3 series.
The Radeon RX 7900 was released more than a month after AMD’s Radeon RX 7700 XT and 7800 XT graphics cards. These upgrades to the RDNA 3 generation of AMD GPUs included 12GB and 16GB of GDDR6 VRAM, attempting to close the gap between the RX 7600 and RX 7900 XTX models in the mid-range market.
AMD maintains its focus on closing the gap with Nvidia in the competitive graphics card market, catering to budget-conscious PC gamers looking for affordable upgrades in 2023 and 2024 with a focus on increased VRAM compared to cards like the Nvidia GeForce RTX 4070 and improved ray-tracing performance compared to the previous RDNA 2 generation.
AMD has presented a tempting choice for gamers looking for a portable solution. Currently, the RX 7900M can only be purchased on Dell’s Alienware m18 gaming laptop, which costs $2,799.99 directly from the seller. Dell has teamed the RX 7900M with AMD’s Ryzen 9 7945HX mobile CPU, which boasts a 16-core processor capable of hitting 5.4 GHz and utilizing AMD’s 3D V-Cache technology to increase gaming performance, even though it isn’t the most affordable choice. The RX 7900M itself claims a base clock speed of 1825 MHz, with potential increases up to 2090 MHz depending on the game, and a total graphics power of up to 180 watts, more than twice that of the RX 7600M mobile GPU.
Due to its support for 1440p resolutions, the Radeon RX 7900M belongs to the same category as the aforementioned Radeon RX 7700 XT and Nvidia’s RTX 4080 mobile variant. The 7900M displays an average performance gain over the RTX 4080 of about 7%, particularly in raw rasterization. The RX 7900M managed frame rates of 79 and 133 FPS, respectively, in games like Forza Horizon 5 and Doom Eternal, showing that Nvidia still has a little advantage in ray-tracing capability.
