Who each one is for
Buy the Razer Core X for shoppers hunting the enclosure on the used/discounted market, though it is not built for anyone wanting the fastest Thunderbolt 5 bandwidth available today and Apple Silicon Mac owners needing official eGPU support. The same goes for buyers who want Core X Chroma capacity without paying for RGB lighting. The Sonnet eGFX Breakaway Box 650 is the one to take for RTX 3060/3070-class double-wide card builds on Thunderbolt 3. It is equally the pick for Mac users wanting official Apple eGPU certification on a mid-tier budget. It is not the one for RTX 3080 Ti/3090 or RTX 40-series cards that want more PSU headroom. Our rating of the Razer Core X (7.5/10): A no-frills, high-value Thunderbolt 3 enclosure that remains one of the best-regarded budget eGPU boxes even years after launch. Our rating of the Sonnet eGFX Breakaway Box 650 (7/10): the right-sized Sonnet box for mid-range Thunderbolt 3 cards, officially Mac-certified.
