    Technical Notes

    • eGFX Breakaway Box models support up to a standard full-height, full-length, double-width card. Cards with three power connectors are not supported.
    • While the eGFX Breakaway box features a 40Gbps Thunderbolt 3 interface, some computers equipped with Thunderbolt 3 use an x2 PCIe lane implementation of Thunderbolt 3 technology that limits PCIe performance to 20Gbps. Full performance also requires the use of the included Thunderbolt 3 (40Gbps) cable, or other Thunderbolt 3 (40Gbps) cables; look for the Thunderbolt icon AND the number 3 on the connector housings to identify these cables.
    • A few professional applications (such as DaVinci Resolve or Cinema 4D) have menu options to use the external GPU even if the app is run on the internal monitor. Final Cut Pro requires 10.14.1+ for external GPU acceleration.
    • Ultimate gaming performance is attained by using a display attached to eGPU.
    • See Using eGPU with Parallels Desktop for Mac.
    • Not compatible with VIVE Wireless Adapter.
    • Neither Apple, nor AMD, nor Sonnet support eGPUs on Thunderbolt 2 or Thunderbolt  Macs. There is a method to support Thunderbolt 2 and Thunderbolt Macs from Purge-Wrangler. Not every Mac is supported. If your Mac has a discrete NVIDIA eGPU, this method will not work. If you have any trouble, our support teams cannot assist you.
    • Power adapter cable for Avid Pro Tools | HDX card sold separately.
    • Plus power delivery to laptop, if activated.
    • Under macOS 10.15.1, a 2018 to current Mac mini is compatible with a Breakaway Box with a Vega 56, Vega 64, WX 8200, WX 9100, Radeon 5700, or Radeon 5700 XT. A 2018 to current Mac mini with a Breakaway Box with an RX560/570/580/590 must be booted with a monitor connected to the Mac mini’s HDMI port. The monitor may be moved to the GPU after booting.
