Verdict
Blackmagic Design Blackmagic eGPU Pro
7 / 10 Expert Rating
The strongest official Mac eGPU of the Intel era, let down only by its high price and total discontinuation after Apple Silicon dropped eGPU support.
OWC Mercury Helios 3
6 / 10 Expert Rating
Solid basic Mac eGPU box, superseded by the Helios FX which OWC still actively sells.
