Built for creators and competitive gamers

The Alienware 16X Aurora laptop targets users who need desktop-class performance in a 16-inch portable chassis. Its Intel Ultra 9 290HX processor with 24 cores handles heavy multi-threaded workloads, content creation, and modern gaming. Windows 11 Pro provides the operating environment for professional applications and high-refresh gameplay.

240 Hz 3K display with G-SYNC

The 16-inch panel runs at 2560x1600 resolution and a 240Hz refresh rate, covering 100 percent DCI-P3 colour gamut. NVIDIA G-SYNC synchronises the panel to the RTX 5070 GPU, eliminating screen tearing during fast motion. This combination decides whether the laptop suits competitive play and colour-critical editing.

Bundled mousepad and biometric camera

A Traix mousepad is included for immediate desktop-style control on any surface. The 1080p FHD RGB-IR HDR webcam enables Windows Hello facial recognition and high-quality video calls. Dual-array microphones and Realtek-tuned stereo speakers complete the communications kit for meetings and in-game chat.
