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.
GIGABYTE RX 580 Gaming Box
6 / 10 Expert Rating
A dated but genuinely plug-and-play option for 1080p eGPU gaming, now most sensible as a budget used-market pickup rather than a current recommendation.
