Connect a High-Performance Graphics Card or Other Bandwidth-Hungry PCIe Card to a Thunderbolt™ 3 Equipped Computer
Sonnet’s eGFX Breakaway Box, a Thunderbolt 3 to PCIe card expansion solution, supports any Thunderbolt compatible PCIe card, but is designed specifically for bandwidth-intensive video graphic cards. The Breakaway Box enables all the popular GPU cards that support connecting to a computer over Thunderbolt such as AMD Radeon® R9 and RX and NVIDIA® GeForce® GTX7, 9 and 10 series, providing GPU support for computationally-intensive applications and games.
Supports AMD XCONNECT Technology
Graphic Intensive Gaming
There’s no need to carry a heavy and expensive gaming laptop to have a great gaming experience—just plug in a Breakaway Box and add the GPU power you want when you need it! By delivering much higher frame rates for smooth game play, the Breakaway Box is ideal for enabling graphic-intensive gaming on computers (such as thin/light notebooks) that otherwise would not be able to produce an acceptable gaming experience. When used with computers that properly support eGPUs, accelerated graphics can either be displayed on your notebook’s own display panel or on external monitors. And, unlike with gaming laptops, when the next generation of GPUs rolls around and you are ready for another performance boost, simply upgrade the GPU card—nobody should have to replace their computer just to keep up with the latest in GPU technology.
Ready for Work, Coolest & Quietest eGFX Graphics Card Box on the Market
In addition to eGPU cards, the Breakaway Box supports every other Thunderbolt-compatible PCIe card, regardless of the card's length or width—its single x16 PCIe 3.0 slot easily accommodates full-length cards such as the RED Rocket-X or AVID Pro Tools|HDX. The Breakaway Box’s single-port 40Gbps Thunderbolt 3 interface ensures the full 2750 MB/s of PCIe bandwidth(1) is dedicated to the installed card.
The Sonnet eGFX Breakaway Box is the coolest and quietest eGFX box on the market—with its large variable-speed, temperature-controlled fan that quietly and effectively cools the installed card, the Breakaway Box can be comfortably used in noise-sensitive working environments.
For Media Professionals
In today’s 4K workflows, harnessing the computational engine in today’s GPU cards is essential to keeping up with on-set and post production timelines. The eGFX Breakaway Box is ideal for supporting the acceleration of special effects, animation, color grading, rendering, and editing.
40Gbps Thunderbolt 3 Performance
Thunderbolt 3 is a leap forward in every way. Whether you’re editing 4K video at high frame rates or blasting aliens out of the sky, you can now transform your notebook into a true desktop experience. With up to 2750 MB/s available bandwidth(1), the Breakaway Box exploits its 40Gbps Thunderbolt 3 interface to offer the best-possible eGPU experience, or handle the most demanding, highest performance PCIe cards.
All models include a 0.5-meter Thunderbolt 3 (40Gbps) cable to connect the box to your computer. Whichever model you choose, the Breakaway Box is Thunderbolt Certified for Mac and Windows.

GPU card use see tech note 2
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. Find more computer information here. 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.
Other than macOS High Sierra Developer Beta, macOS does not yet support connection of GPU cards over Thunderbolt and GPU card drivers are not yet officially Thunderbolt compatible for macOS.
Choose eGFX Breakaway Box model that supports the power requirement of the chosen card.
