eGPU

An eGPU is primarily designed to allow smaller notebook computers to benefit from the power of a full-sized graphics card via a high speed bandwidth connection.

Apple officially rolled out eGPU support in macOS with the release of macOS 10.13.4. eGPUs require a Thunderbolt 3 connection to work with Macs, meaning only Thunderbolt 3-enabled Macs are eligible.

macOS only supports AMD GPUs, like the AMD Radeon RX Vega 64. Several eGPU chassis/card combinations are officially recommended by Apple, including Sonnet’s eGFX Breakaway Box 650W.
