Last updated Oct 3, 2026

Device Type: External GPU

This is an external GPU enclosure that connects to a laptop over Thunderbolt — not a graphics card you install inside a desktop PC.

Despite the name, the GPU inside is the laptop-class part, not the desktop chip of the same name.

Prices shown are for the complete enclosure, not a bare graphics card, so we don't publish a value score for these.

Overview

The ASUS ROG XG Mobile with the NVIDIA GeForce RTX 4090 Laptop GPU is an external graphics dock from 2023 that adds high-end discrete graphics to compatible laptops, handhelds and mini PCs using a single cable. Launched in February 2023, it belongs to the generation before the Thunderbolt 5 models and connects through ASUS's proprietary XG Mobile connector. It ships with a 330W adapter and doubles as an I/O hub for the host device.

Inside is an RTX 4090 Laptop GPU built on the Ada Lovelace architecture, with 16GB of GDDR6 memory and a 150W power target. The combination delivers flagship-class mobile graphics for gaming, rendering and creative work in a docked form factor. It is aimed at owners of XG Mobile-compatible systems who want desktop-level graphics performance at home or on the move without carrying a separate desktop.
