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.
Razer Core
5.5 / 10 Expert Rating
Historically important as one of the first Thunderbolt 3 eGPU boxes, but long superseded by the quieter, more compatible Core V2 and Core X.
