Introduction

In a bold move, Asus has just released what it claims to be the world’s first Thunderbolt 5 external graphics card, the 2025 Asus XG Mobile. This revolutionary device, showcased in a sleek smoky black translucent design, serves not merely as a gaming PC but as a potential powerhouse in the realm of portable docking stations.

Key Features and Specs

When connected to your laptop or handheld device, the XG Mobile promises to unlock the incredible capabilities of Nvidia's top-performing GeForce RTX 5090 mobile chip, alongside delivering up to 140 watts of power, the ability to support two monitors, and act as a USB and SD card hub, all while providing 5Gbps ethernet connectivity.

This unprecedented development utilizes the latest Thunderbolt 5 technology, boasting bidirectional speeds of up to 80 gigabits per second. This means users can achieve more with a single cable than previously imaginable, paving the way for seamless high-performance graphics and extensive connectivity.

Comparison with Previous Generation

Interestingly, while Asus’s previous generation XG Mobile topped out at an Nvidia 4090, that model was limited to a proprietary port exclusive to select Asus devices. In contrast, the new Thunderbolt 5 dock opens a realm of possibilities for broader compatibility, supporting a range of devices beyond Asus’s ecosystem.

Performance and Design

Currently, performance metrics for the XG Mobile remain under wraps, so it’s unclear if it will dethrone other eGPUs in raw power. However, it does promise up to 64Gbps of bandwidth, closely matching that of Oculink, and significantly surpassing USB4. What’s more, Asus has accomplished the feat of incorporating a 350W power supply into a lightweight design weighing less than 2.2 pounds, complete with a convenient fold-out kickstand.

Comparatively, the XG Mobile is 25% lighter and 18% smaller than its predecessor, showcasing Asus's commitment to compact design without sacrificing functionality. The device features HDMI 2.1 and DisplayPort 2.1 outputs, along with two 10Gbps USB-A ports for maximum versatility.

Pricing and Availability

Set to launch later in Q1, the pricing is indeed premium. The high-end model featuring the RTX 5090 will retail for $2,199.99, a steep investment for sure. For those seeking a more budget-friendly option, Asus will also offer a version equipped with the RTX 5070 Ti for $1,199.99. It’s essential to note that while these devices deliver remarkable power, users seeking ultimate performance for their bucks may find greater value in building a traditional desktop setup.

Compatibility

Compatibility doesn’t seem to be an issue as the XG Mobile will work with Thunderbolt 4 or USB4 laptops and handhelds, including Asus's ROG Ally X. However, to fully leverage the capabilities of the GPU, opting for a Thunderbolt 5 device is highly recommended.

Conclusion

As technology continues to evolve, especially with the emergence of thinner, lightweight laptops in 2025, the landscape may shift, bringing more options for users eager to double their laptops' capabilities while on the go.

Will This New eGPU Redefine Mobile Gaming?

The potential of Thunderbolt 5 applications is vast, and as we await further details on this device's performance, it seems the battle for mobile gaming supremacy has just begun. Stay tuned for more updates as we continue to follow this exciting development in the tech landscape!
