The first AMD Radeon RX 7900M benchmark has appeared online, suggesting the upcoming laptop GPU is 4% faster than its direct rival, the Nvidia GeForce RTX 4080 laptop graphics card. AMD’s new, flagship mobile Radeon powers a new version of the Alienware M18 gaming laptop.

YouTube tech channel GizmoSliPTech tested the new Alienware M18 laptop powered by AMD‘s latest mobile graphics card and was impressed by the results. The laptop scored 19,743 points in the 3DMark Time Spy benchmarking tool, thanks to the AMD Radeon RX 7900M’s strong performance.

This beats out the Nvidia GeForce RTX 4080 laptop GPU, which recorded a score of 18,923 in the 3DMark rankings, by just over 4%. That’s a little lower than the official gaming benchmarks released by AMD which boasted a 7% performance boost versus the Nvidia card.

The AMD Radeon RX 7900M is the first laptop GPU powered by the Navi 31 GPU, which also powers high-end cards like the AMD Radeon RX 7900 XTX. It’s currently only available in the Alienware M18 laptop, where it accompanies the AMD Ryzen 9 7945HX.

Here are the AMD Radeon RX 7900M specs:

Graphics card AMD Radeon RX 7900M
Compute units 72
Clock speed 1,825MHz
Boost clock speed Up to 2,090MHz
Memory 256-bit
Infinity cache 64MB
TDP 180W

Presumably, AMD will roll out its flagship laptop GPU to more devices in the future. If so, it will be interesting to see how they stack up against the best gaming laptops available at the moment.
