    Technical Notes

    • eGPU Breakaway Box models support up to a standard full-height, full-length, double-width card. Cards with three power connectors are not supported.
    • While each eGPU Breakaway Box 750 model 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. eGPU Breakaway Box 750ex divides bandwidth between the installed GPU card and connected peripherals when connected peripherals are operating.
    • 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.
    • 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 10.14.6, a Mac mini is compatible with a Breakaway Box with Vega 56, Vega 64, WX 8200, and WX 9100. A Mac mini with a Breakaway Box with an RX 560/570/580/590 must be booted with a monitor connected to the Mac mini’s HDMI port. The monitor may be moved to the GPU after booting. This anomaly is fixed in macOS 10.15.7+.
    • 8K displays require a GPU card that supports 8K displays.
    • For example, the AMD Radeon Pro W5700 has a USB-C Alt-Mode DisplayPort output.
