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 Dell documentation, which lists 2 × TB5 + 2 × TB4, together with the configuration details shown above.

Compare Thunderbolt 5, Thunderbolt 4 and USB4

What it changes for workstation use

Thunderbolt 5 can connect a workstation to compatible docks, displays, external storage and specialized peripherals. The standard alone does not tell you how many displays the laptop supports or whether a dock can power it. Check the specifications for the exact laptop and accessory before planning the setup.

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.
