Verdict

Lenovo ThinkPad Thunderbolt 3 Graphics Dock

4.5 / 10 Expert Rating

A promising idea — dock plus eGPU in one — undermined by well-documented compatibility and reliability issues at launch.

Plugable Thunderbolt 5 AI eGPU Enclosure & Dock

7 / 10 Expert Rating

A genuinely differentiated, well-specced Thunderbolt 5 eGPU box for local-AI GPU hosting, but it's brand new, Windows-only, and still awaiting independent benchmarking — treat the manufacturer's numbers as a starting point, not a verified ceiling.
