Connect a High-Performance Graphics 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 graphic video cards. The Breakaway Box enables all the popular GPU cards that support connecting to a computer over Thunderbolt such as AMD Radeon® and Radeon Pro; NVIDIA® GeForce®, TITAN X, and Quadro® cards, providing GPU support for computationally-intensive applications.

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 upgradable 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 3 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. The Breakaway Box’s single-port 40Gbps Thunderbolt 3 interface ensures the full 2750 MB/s of PCIe bandwidth is dedicated to the installed card.
