ASUS Republic of Gamers has announced the ROG XG Station 3, an open-frame external graphics dock that connects to a laptop over Thunderbolt 5 and takes a desktop graphics card from NVIDIA, AMD or Intel. In its press release dated November 3, ASUS lists GeForce RTX 50 Series, RTX PRO 6000 Series, Radeon RX 9000 Series and Intel Arc cards as supported.
Thunderbolt 5 carries up to 80Gbps each way, or 120Gbps with Bandwidth Boost for video
ASUS puts the dock’s link at up to 80Gbps of bidirectional bandwidth, twice what it says Thunderbolt 4 offers, and up to 120Gbps with Thunderbolt 5 Bandwidth Boost for high-volume video traffic. The same upstream port delivers up to 140 watts of USB Power Delivery, enough in ASUS’s words to fully power a wide range of laptops through one cable. A second Thunderbolt 5 port faces downstream: it can daisy-chain USB-C monitors for up to three 4K displays and supply 36 watts to peripherals, which ASUS notes is a feature graphics cards do not typically offer. Two USB 10Gbps Type-C ports on the front complete the I/O hub.
A GC-HPWR slot lets BTF 2.5 cards draw power through the dock instead of a visible PCIe cable
The dock is open-frame so the card sits in view with unobstructed cooling, and a standard card would leave its PCIe power cable showing. The XG Station 3 therefore includes a GC-HPWR slot for BTF 2.5 cards, which ASUS says can draw power without a visible cable. It lists the TUF Gaming GeForce RTX 5080 BTF OC Edition and the ROG Astral GeForce RTX 5090 BTF Edition. Aura Sync lighting is supported.
The release gives no price, release date, power supply rating or frame rates
ASUS says the dock lets compatible laptops reach desktop-caliber gaming performance and cites the ROG Zephyrus G14 as an example of a compact machine that could use one, but the release carries no frame rates, no comparison with the same card in a desktop, and no price or release date. It also cites the ROG Astral RTX 5090 without saying what power supply the dock contains, which may leave open whether it can run a card of that class at full load. A buyer weighing the dock against a gaming desktop has nothing in the announcement to compare yet.
