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 MAINGEAR documentation, which lists 2 × TB5, together with the configuration details shown above.
Compare Thunderbolt 5, Thunderbolt 4 and USB4What 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.

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.
