Verdict
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Historically important as one of the first Thunderbolt 3 eGPU boxes, but long superseded by the quieter, more compatible Core V2 and Core X.
Sonnet eGFX Breakaway Box 350
6 / 10 Expert Rating
A niche but well-executed pick for single-slot cards and quiet operation, not for gaming-class GPUs.
