Asus has just launched the ROG XG Mobile (2025) in the US, nearly a year after revealing this new eGPU solution at CES 2025 in Las Vegas. To remind you, EXcaliber PC started selling the 2025 models a bit over two weeks ago. However, up until now, we didn’t know when Asus would begin its direct sales of the ROG XG Mobile (2025).

Pricing and Specifications

The ROG XG Mobile (2025) has a starting price of $1,299.99 and comes equipped with an Nvidia GeForce RTX 5070 Ti laptop GPU, which features 12 GB of GDDR7 VRAM. Interestingly, you can also find this model available on Amazon US for the same price. On the other hand, the GeForce RTX 5090 laptop variant costs $2,499 and offers 24 GB of GDDR7 VRAM, while keeping Thunderbolt 5 (120 Gbps) connectivity, a revamped vapor chamber cooling system, and a 330 W integrated power supply.

Availability Issues

At the moment, both RTX 5070 Ti and RTX 5090 models are backordered at Newegg. Additionally, B&H Photo Video has plans to offer the RTX 5090 version, but this option is only marked as ‘coming soon’ right now. Unfortunately, Asus has only announced that the ROG XG Mobile (2025) will be priced from £1,399 in the UK, with no details on pricing for the Eurozone. Comparatively, the 2025 editions are priced at AU$4,999 and CA$1,999 in Australia and Canada, respectively.

Early Reviews

In the meantime, early reviews from Cyber Dopamine and ETA Prime have highlighted the GeForce RTX 5090 variant. Both reviewers commend the performance uplift that the ROG XG Mobile (2025) offers for AAA gaming titles. Likewise, the RTX 5090 version shows impressive results in 3DMark Steel Nomad and 3DMark TimeSpy, closely trailing similar high-end gaming laptops.

The eGPU significantly enhances Geekbench 6 OpenCL scores by over three times when compared to the Radeon 890M iGPU found in a ROG Xbox Ally X. That said, gaming handhelds are restricted to USB4 or Thunderbolt 4 ports, meaning they can’t currently utilize the full potential of the eGPU’s Thunderbolt 5 bandwidth.
