Frequently Asked Questions

Q: What laptops are compatible with the TH3P4 Lite GPU Dock?

A: The TH3P4 Lite GPU Dock is compatible with any laptop that features a Thunderbolt 3 or Thunderbolt 4 port. Simply connect using the included Thunderbolt data cable to get started — no additional adapters required.

Q: What PCIe devices can I use with this GPU Dock?

A: The dock supports any PCIe-interface card — including compute cards, capture cards, and similar devices — as long as they operate within the 75W power envelope. Both full-height and half-height cards are supported thanks to the included bracket set.

Q: What makes the JHL7440 chip better than older Thunderbolt controllers?

A: The JHL7440 chip overcomes the bandwidth limitations found in both the JHL6xxx series (capped at 22 Gbps) and the PCIe restrictions of the JHL8xxx series. It achieves a true 32 Gbps PCI-E 3.0 x4 transfer speed, unlocking significantly faster data throughput for external graphics and compute tasks.

Q: Does the TH3P4 Lite GPU Dock support daisy-chaining or USB hub functions?

A: No — the TH3P4 Lite is purpose-built for maximum PCIe bandwidth. Daisy-chaining, USB hub functionality, and PD charging are not supported on this model, keeping the focus on delivering the fastest possible external GPU connection.
