The high-end gaming market is heating up once again as we see competition from both Nvidia and AMD. In a debut working with Dell, AMD has launched its brand new RX 7900M, which is now the fastest-ever mobile GPU to be developed by the company. To be included in high-performance gaming laptops, the RX 7900M just might challenge the RTX 4080. Let’s explore the features and specs of this new AMD Radeon RX 7900M GPU for gaming laptops and see how it fares against the RTX 4080 laptop GPU!

AMD Launches Its Fastest-Ever RX 7900M Laptop GPU: Details

Announced in a press release, the AMD Radeon RX 7900M is the company’s fastest AMD Radeon laptop graphics ever developed. The GPU is based on the RDNA 3 architecture-based graphics card built from the ground up to provide high-end graphics performance to future gaming laptops. The RX 7900M is based on the Navi 31 processor, making it the first laptop GPU based on a chipset design. GPUs built on a chipset design offer advantages over monolithic design.

Advantages of the RDNA 3 Architecture

According to AMD, the RDNA 3 architecture delivers next-generation performance and leadership performance per watt. With 72 compute units, 64MB of infinity cache, and AV1 Codec support for high-quality game streaming, the RX 7900M offers top-notch performance and features dedicated AI acceleration hardware and second-gen ray-tracing technology.

The Ultimate AMD Advantage Laptop

AMD has teamed up with Dell to make the Alienware m18 the first one to take advantage and be labeled as the ultimate AMD Advantage laptop. The new gaming laptop leverages the Ryzen 9 7945HX processor coupled with the newly unveiled RX 7900M GPU. AMD offers this new laptop GPU with 16GB GDDR6 VRAM and up to 180W, providing gamers with high video memory capacity and wattage they will appreciate.

Performance Comparison: RTX 4080 vs RX 7900M

According to performance comparisons, the AMD Radeon RX 7900M is 7% faster on average in selective games compared to the Nvidia RTX 4080, including Far Cry 6 and Doom Eternal with ray-tracing enabled. However, the RTX 4080 performs better in other titles and likely has better ray-tracing performance overall. More performance comparisons will provide further insights once the new RX 7900M GPU becomes widely available.
