ROG Strix G18 (2025)

Configuration-dependent. Thunderbolt 5 is SKU-dependent on the 2025 ROG Strix G18. ASUS lists two TB5 ports on three specific US configurations and TB4 on its other listed G815 versions.

One of those TB5 identifiers, G815LW-G18.U95080, has a complete retail record with an RTX 5080, 32GB of memory and a 2TB SSD. The other two identifiers remain family documentation until their complete specs are tied to one SKU.

Reading the guide

What these details mean

The connector, Thunderbolt version and retail code answer different questions.

The connector does not identify the standard

Thunderbolt 5, Thunderbolt 4 and USB4 can all use a USB-C connector. A port photo cannot tell you which standard is present. For this family, rely on the ASUS documentation, which lists 2 × TB5 on three listed US SKUs, together with the configuration details shown above.

What it changes in a gaming setup

Thunderbolt 5 affects external connections, not the speed of the laptop's built-in CPU or GPU. Its practical role is to connect compatible docks, displays, storage and other peripherals. Display modes, charging behavior and device performance still depend on both the laptop and the accessory.

Complete cards and partial records

This guide has two levels of detail. The exact cards above tie a retail identifier to CPU, GPU, memory and storage. The additional manufacturer records omit at least one of those details, so use them to understand the family, not as a substitute for a complete SKU at checkout.
