Connect a High-Performance Graphics Card or Other Bandwidth-Hungry PCIe Card to a Thunderbolt 3 Equipped Computer

Sonnet's eGFX Breakaway Box Thunderbolt 3 to PCIe card expansion systems are designed specifically for GPU-intensive graphics cards. Functioning as a simple plug-in upgrade, a Breakaway Box boosts performance by connecting a high-performance desktop GPU card to a Thunderbolt 3-equipped computer. All models provide GPU support for computationally-intensive applications, supporting all Thunderbolt-compatible cards with popular GPU chipsetssuch as AMD Radeon, Radeon Pro and VEGA; NVIDIA Geoforce, TITAN X, and Quadro cards.

Graphic Intensive Gaming
Gamer with eGFX Breakaway BoxTheres no need to carry a heavy and expensive gaming laptop to have a great gaming experiencejust 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 notebooks 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 cardnobody should have to replace their computer just to keep up with the latest in GPU technology.

Ready for Work, Coolest and 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 widthits single x16 PCIe 3.0 slot easily accommodates full-length cards such as the RED Rocket-X or AVID Pro Tools|HDX.(4)

The Breakaway Boxs 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 marketwith 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.

Liquid Coolers Supported
The eGFX Breakaway Box supports 120mm x 1, single fan radiators. Water block coolers run quieter than active fans; plus water block coolers enable higher overclocking.

For Media Professionals
In todays 4K workflows, harnessing the computational engine in todays 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 youre 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.
