ROG XG Mobile: Take Your Laptop’s Graphics to the Next Level
An external GPU (or eGPU) can increase your device’s graphical capabilities in a similar way to how an external hard drive can increase its storage. In addition to powering your computer, the ROG XG Mobile line of external graphics cards is small enough to carry around with you, allowing you to continue playing games while on the road.
If your laptop has a Thunderbolt 5, Thunderbolt 4, or USB4 connector and is running Windows 11 24H2, you can use the 2025 ROG XG Mobile external graphics card to give your computer the power of a powerful, heavyweight NVIDIA 50 Series laptop GPU. The ROG XG Mobile external GPU is lightweight and around the size of a hardback book, in contrast to many eGPU enclosures that are large and made to be left on a desk all day. This implies that you can easily fit it in a backpack with your laptop. Furthermore, the XG Mobile will boost your computer regardless of whether you connect it to a desktop, a gaming laptop, or a regular laptop.
Maybe you desire additional graphical power to play the newest games on your incredibly light and thin ASUS Zenbook S16. No issue: simply connect in the ROG XG Mobile, and you’ll have a top-tier gaming device. This configuration gives you a very versatile big-screen gaming setup when paired with a monitor. Multi-monitor setups are a breeze with the ROG XG Mobile’s amazing bandwidth, which allows it to support up to three 4K displays at 144Hz and support 8K video.
With up to an NVIDIA GeForce RTX 5090 Laptop GPU available in this year’s 2025 ROG XG Mobile options, you can instantly transform your current laptop into a powerful gaming device. Additionally, the Blackwell architecture of the 50 Series GPUs offers you a host of advanced, AI-powered advantages. DLSS 4 with Multi Frame Generation, up to 75% latency reduction with NVIDIA Reflex 2, next-level graphical fidelity with NVIDIA RTX Neural Shaders, and more are all available to you. You can play the newest games for years to come with enhanced framerates, better graphics, and more with these technologies that let your GPU perform above its weight class.
What can you upgrade on a gaming laptop?
The age-old argument between portability and performance still exists between gaming laptops and desktop computers. ROG is dedicated to delivering the advantages of desktop PC gaming to the portable laptop form factor in order to close this gap. All of gaming laptops have upgradeable storage because of this. Since the size of games is increasing daily, make it simple to upgrade your collection when it exceeds its maximum. To upgrade your ROG Zephyrus laptop, ROG Strix laptop, or ROG Flow Z13 laptop, simply take out your screwdriver and follow instructions.
The aggressive upgradeability efforts are best exemplified by ROG Strix notebooks, which support both RAM and storage upgrades. In recent years, the RAM needs for AAA games have increased from 8GB to 16GB and now to about 32GB. For this reason, it guarantee that you may add more RAM to your current ROG Strix laptop anytime necessary.
Many Strix machines can be completed with just a screwdriver (as seen in the tutorial mentioned above), but 2025 Intel-based Strix SCAR and Strix G are really unique since they have a whole new tool-less design. This implies that you may easily increase your laptop’s RAM and storage by flipping a switch to remove the bottom panel. It Q-latch technology allows you to secure the SSD without ever using a screwdriver.
Beyond ROG XG Mobile
The XG Mobile is a remarkably small device that is about the size of a hardback book and combines the capabilities of an external GPU with the expandability of a Thunderbolt Dock. With a maximum GPU capacity of NVIDIA GeForce RTX 5090, this portable powerhouse is built to play games at the highest levels.
In addition to improving your gaming experience, the XG Mobile uses Thunderbolt 5’s amazing bandwidth to provide a variety of connectivity options, such as wired Ethernet and fast USB ports, all in a small package. The ROG XG Mobile is now available for producers who require flagship rendering capabilities from a single Thunderbolt connection or gamers who require significant power without compromising the portability of their system.
COMPATABILITY
Thunderbolt 5
Thunderbolt 5 debuted with the 2025 ROG XG Mobile. The XG Mobile supports three 4K screens at 144Hz and 120Gbps, double Thunderbolt 4’s bandwidth. It also allows for high-speed data transmission as a USB hub and supports 8K video for artists.
PERFORMANCE
CUTTING-EDGE GRAPHICS
The amazing performance of an NVIDIA GeForce RTX 5090 laptop GPU is available to both makers and gamers. With a maximum TGP of 150W and up to 24GB of GDDR7 VRAM, the XG Mobile is the ideal partner for creators who need to carry the power of a top-tier editing machine with them wherever they go or for gamers who need the greatest performance possible in AAA games.
- Up to NVIDIA GeForce RTX 5090 Laptop GPU
- Up to 24GB GDDR7 VRAM
- Up to 150W Max TGP
DESIGN
Smaller and lighter
ROG consistently built the XG Mobile to be around the size and weight of a typical hardback novel because traditional external graphics cards require bulky desktop enclosures. In contrast to the previous generation, we took things a step further this year by making the device lighter and smaller overall. With a weight of less than 1 kilogram, the 2025 ROG XG Mobile is lightweight enough to be transported anywhere you need to go without hesitation. It will also fit neatly into even the tiniest bags and backpacks.
- 25.4% Smaller
Cutting-edge MOSFETs
By regulating power delivery using brand-new active bridge rectifier MOSFETs rather than conventional diodes, the 2025 ROG XG Mobile maintains a 330W power profile while reducing size and weight. This enabled us to reduce the power board’s weight by 150g while simultaneously improving power efficiency. The XG Mobile offers dependable performance in any situation with these MOSFETs, which are particularly helpful in lowering voltage drop in high-current applications.
LEAN IN
For 2025, the XG Mobile has a new hinge that is significantly lower profile and takes up less desk space. The distinctive ROG Slash design language is hinted at on the stand. If you like that appearance, we’ve also included a stand in the box that enables the gadget to stand upright.
See the power
Its wanted to showcase the 2025 XG Mobile’s components to the world since we are so proud of them. A peek inside this engineering marvel is provided by an off-black semi-transparent chassis, which displays its sturdy power delivery modules and other surface-mounted components on the mainboard together with a completely RGB
THERMAL
With this much power, especially in such a compact package, a state-of-the-art cooling solution is needed. The 2025 ROG XG Mobile boasts the most sophisticated cooling system ever with a new vapor chamber, a lighter fan shroud, an integrated dust filter, and a redesigned fan positioning.
Brand New Vapor Chamber
Compared to a conventional heatpipe system, a copper vapor chamber increases cooling efficiency without adding bulk by allowing for greater surface contact with heat-generating components. With 50% thicker capillary structures and a brand-new copper vapor chamber, the 2025 XG Mobile maintains thermal performance while lowering weight by 30%.
Ultra-thin Fins
Ultra-thin fins contribute to weight reduction without compromising cooling effectiveness.
Dust Filter
To ensure that the fans continue to breathe clean air, the 2025 XG Mobile has a dust filter to keep dust and other particulate matter out of the system.
Quieter Vent Layout
The 2025 ROG XG Mobile reduces noise by 3dB by positioning the fan assembly as far away from the user as feasible.
IO PORTS
Numerous connectivity possibilities are readily supported by the XG Mobile. The XG Mobile has many next-generation connectivity options, including a 5Gbps Ethernet port, HDMI 2.1, and DisplayPort 2.1.
