Pro Power Graphics Add a High-performance Video Card to Create Your Own Personal eGPU Workstation

Transform Your Thunderbolt Computer Into a Graphics Workstation 

Whether you’re editing, rendering, color grading, animating or creating special effects, many of the pro applications you use rely on desktop and workstation graphics (GPU) cards to do the heavy lifting in processing data. Unfortunately, many popular computers are equipped only with integrated graphics or low-power discrete GPUs that bottleneck performance when performing these tasks. Happily, there’s a simple path to greater productivity—add a Sonnet external GPU (eGPU). The eGPU Breakaway™ Box 750 and 750ex Thunderbolt™ to GPU PCIe card expansion systems boost your eGPU-compatible computer’s graphics performance by connecting a high-performance GPU card to your computer via a single cable.

Future-proof Upgrade

With each new generation of GPU cards, users can look forward to a step (or leap) forward in performance. Less predictable is how much power they will require to operate—better performance frequently requires increased power. For eGPU users, power consumption can be a concern. Don’t limit your future video graphics card choices—choose a Sonnet eGPU Breakaway Box 750 or 750ex. Equipped with 750W power supplies, these Sonnet chassis easily support the highest power demands of latest GPUs and have plenty of extra power to support GPU cards from generations to come.

Three Models. Your Choice:

All eGPU Breakaway Box models are Thunderbolt Certified and include a Thunderbolt cable to connect the system to your computer. The 750 offers basic eGPU functionality. The 750ex provides a handy connection hub for USB devices and Ethernet connectivity, while the 750ex with AMD Radeon RX 6900 XT includes one of the most powerful GPU cards ever.

No Compromise GPU Card Choice

eGPU Breakaway Box 750 systems are designed specifically to accommodate the most power-hungry double-width GPU cards. They support Thunderbolt-compatible cards(1) with popular GPU chipsets—such as AMD Radeon™ RX series GPUs, and NVIDIA® GeForce® series and TITAN GPUs. Even the latest pro cards—AMD Radeon Pro and NVIDIA Quadro® GPUs—are supported! (Note that macOS® supports only AMD GPU cards in eGPU systems, while Windows® supports AMD and NVIDIA cards.) With a GPU card installed, a Breakaway Box functions as a simple plug-in upgrade to significantly accelerate the demanding needs of your video production workflow.

Performance Comparisons With eGPU vs Without Application eGPU Performance Examples Connecting a desktop or workstation GPU card delivers a significant graphics processing boost to the top video editing, visual effects, and modeling applications, cutting rendering times and enhancing VFX and color correction workflows. These performance comparisons illustrate potential advantages with popular eGPU cards and applications.
GPU vs GPU Radeon Pro WX 9100 vs Radeon RX 580 Installed in an eGPU Breakaway Box 750, the AMD Radeon Pro WX 9100 offers outstanding performance. The graphs below compare the WX 9100 against the RX 580 (as featured in the custom-designed, all-in-one Blackmagic eGPU). While delivering good performance, the RX580 is greatly outclassed by the WX 9100 for pro-graphics acceleration.

4K to 8K Workflows –
Connect Two or More Breakaway Boxes

Many task times on supported applications—such as Adobe® Premiere® Pro, DaVinci Resolve™, and Maxon Cinema 4D™, to name a few—can be cut significantly with one eGPU Breakaway Box connected. But, for computers with multiple Thunderbolt ports, times can be slashed when two, three, or four Breakaway Boxes are employed. Connecting one or more eGPUs can multiply your computer’s graphics processing power, enabling it to handle 4K, 5K, 6K, and 8K workflows more efficiently. Plus, a computer’s onboard discrete GPU also contributes to the aggregate performance.

More Ports, Additional Functionality: eGPU Breakaway Box 750ex

Is your computer short on ports for basic connectivity? Step up to the eGPU Breakaway Box 750ex to add four 5Gb/s USB 3.2 Gen 1 Type A ports to connect peripherals, plus an RJ45 Gigabit Ethernet port for a wired network connection. The 750ex features a dual Thunderbolt controller design, enabling it to support both peripherals and GPU card through the single Thunderbolt connection to your computer.

Designed for GPU Cards, Also Supports Other Demanding PCIe Cards

The Breakaway Box’s single x16 PCIe 3.0 slot accommodates full-length, double-width cards, and its 750W power supply supports trouble-free operation. Its single-port 40Gbps Thunderbolt interface ensures the full 2750 MB/s of PCIe bandwidth(2) is dedicated to the installed card.

Coolest & Quietest Add-your-own-card eGPU System Available

With its large variable-speed temperature-controlled fan that quietly and effectively cools the installed card, the eGPU Breakaway Box can be comfortably used in noise-sensitive working environments.

Graphic-Intensive Gaming Support

There’s no need for you to carry a heavy, loud, and hot-running 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! A Breakaway Box is ideal for empowering graphic-intensive gaming on an Intel® processor-based MacBook Air® or 13-inch MacBook Pro®, Ultrabook™ and other thin/light notebook computers that otherwise would deliver a poor gaming experience. Accelerated graphics can either be displayed on one, two, or more external monitors, or on your notebook’s own display panel(4). Best of all, you can upgrade the GPU card in the Box to keep up with the latest in GPU technology (unlike with gaming laptops).

Compatible with Thunderbolt 4 Computers

The eGPU Breakaway Box 750 and 750ex are fully compatible with Thunderbolt 4 computers and were purposely designed with a Thunderbolt 3 controller and its four lanes of PCIe (not available in a Thunderbolt 4 peripheral) to achieve maximum performance. Learn more about the performance benefits of Thunderbolt 3 over Thunderbolt 4.
