Verdict
OWC Mercury Helios 3
6 / 10 Expert Rating
Solid basic Mac eGPU box, superseded by the Helios FX which OWC still actively sells.
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Historically important as one of the first Thunderbolt 3 eGPU boxes, but long superseded by the quieter, more compatible Core V2 and Core X.
