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.

PELADN Link S-3

6 / 10 Expert Rating

An interesting, genuinely cheaper-to-build Thunderbolt 5 eGPU option for people who already have a spare ATX/SFX PSU, but inconsistent regional pricing and near-zero independent review coverage mean it's a bigger gamble than the budget framing suggests.
