AMD introduced its new flagship RDNA 3-powered Radeon RX 7900M 16GB cellular GPU, with the primary laptop computer maker to get hands-on with it and get it inside their new gaming laptop computer is Dell with the introduction of the brand new Alienware M18.
Now the nice of us at Notebookcheck.internet have had hands-on with the Alienware M18 gaming laptop computer, and effectively and really put it by means of its paces towards the GeForce RTX 4080 and GeForce RTX 4090 Laptop computer GPUs. The brand new Alienware M18 gaming laptop computer options the AMD Ryzen 9 7945HX CPU alongside the brand new flagship Radeon RX 7800M 16GB GPU.
Of their testing, Notebookcheck.internet stories that CPU efficiency is 10% sooner in uncooked multi-threaded efficiency towards the Intel Core i9-13980HX processor, whereas it is between 5-10% slower in single-threaded efficiency.
On the storage facet of issues, we’ve got the M.2 SSD from Kioxia within the type of the XG8 KXG80ZNV1T02 is a higher-end PCIe4 x4 NVMe SSD with “no throttling points” and excessive switch charges of as much as 6300MB/sec for “prolonged intervals” of time.
The brand new Radeon RX 7900M GPU is considerably sooner than the previous-gen Radeon RX 6800M, with Notebookcheck.internet including that it represents a 2x to 2.5x efficiency enchancment over the 6800M.
Ray-tracing efficiency on the brand new Radeon RX 7900M can also be value noting, the place the location says that the brand new Radeon RX 7900M is the “turning level” that AMD followers have been ready for. The location notes that enabling RT was “beforehand by no means really helpful” on a Radeon-based laptop computer as a result of “immense efficiency loss,” and they’re proper. NVIDIA owns RT on laptop computer, and it has not been one thing anybody would suggest for a Radeon RX 6000-series laptop computer GPU.

In some testing of each Cyberpunk 2077 and F1 22, the location notes single-digit FPS variations between the RX 7900M and RTX 4080. Nonetheless, enabling RT will nonetheless see the efficiency tanking someplace between 15% and 35%, which is important. NVIDIA has its DLSS 3.x AI upscaling, in addition to Body Era, serving to out in an enormous manner, in comparison with FSR3, which does not supply the identical beneficial properties as DLSS 3.x, nor does it have that many video games supporting it.
Cyberpunk 2077 v1.6 runs at 1440p on the Extremely preset at 93FPS common on the Radeon RX 7900M-powered Alienware M18 gaming laptop computer, whereas on the RTX 4090-based m18 R1 gaming laptop computer (with the Core i9-13980HX processor) we’re 102FPS. Shut, for positive.
Enabling RT in Cyberpunk 2077 is fascinating, the place the Radeon RX 7900M drops to 41FPS common at 1080p with RT on the Extremely preset (DLSS disabled) in comparison with the 65FPS on the RTX 4080 Laptop computer GPU.
One other factor to notice is that Alienware is utilizing a cumbersome 330W AC adapter versus the thinner GaN AC adapter that has larger power-per-volume in comparison with conventional AC adapters.
