When you first look at the ASUS ROG Flow X13, you just see another ultra-portable laptop, but if you look closer, you see a port that looks extremely weird, to be frank. That port serves as the connection point to the docking station housing a GPU that comes with the laptop. The ASUS ROG Flow X13 is the first laptop in a long time to be paired with a custom-built eGPU docking station.

The highlight of the ROG Flow X13 is not the laptop itself, rather the ROG XG Mobile eGPU dock. The last time a product similar to this was ASUS' ROG XG Station released in 2007. The design for the XG Mobile was designed to be smaller than the average eGPU. The dimensions are 155 x 208 x 29 mm and it comes in at only 1 kg (2.2 lb) which is 6% of the size of the average eGPU. Inside the docking station is Nvidia's GeForce RTX 3080 GPU clocked at 1810 MHz at 150W with ROG Boost and is cooled by a vapor chamber cooling system. This design increases the contact surface area by 54% compared to the traditional heat pipes.
