The mobile GeForce RTX 5090 maxes out at 175 W compared to 500+ W on the desktop RTX 5090. Consequently, even the fastest mobile RTX 5090 is just barely better than the 150 W or 160 W versions based on our ongoing tests.https://www.notebookcheck.net/Even-the-top-end-175-W-GeForce-RTX-5090-offers-just-minor-performance-benefits-over-the-Razer-Blade-16.990643.0.html
I hope their laptops are better than the rest of their products.
