With triple-width GPU support, ultra-quiet operation, and upgrade flexibility, Breakaway Box 850 T5 is built for serious work — and serious play.

Transform Your Windows Laptop or Small Form Factor Computer Into a Near-desktop Graphics Workstation 

Are you a video pro? Many of the applications you use — whether to edit, render, color grade, animate, or create special effects — require the processing power of desktop or workstation graphics (GPU) cards to efficiently and quickly handle the demanding data processing needs. Because many popular laptops come with either integrated graphics or low-power discrete GPUs, their performance can be severely limited for these tasks. The good news? There’s an easy solution for boosting your productivity — just add a Sonnet Breakaway Box 850 T5 Thunderbolt 5 eGPU to connect your high-performance GPU card to your computer through a single Thunderbolt 5 cable and significantly enhance its graphics performance.

Local AI for Faster Processing and Enhanced Privacy 

So, you’ve purchased a laptop or SFF computer loaded with RAM; a super-fast, high-capacity SSD; and a high-end CPU, but you’re not sure what it can do using the onboard graphics processor. For AI related tasks, maybe not as much as you want it to do. But, when you connect Breakaway Box 850 T5 and install one of the latest GPU cards, you can run local AI apps to perform the tasks you need — with immediate results — without paying for a subscription or per transaction fees.

LLM Libraries

Run Large Language Model (LLM) apps such as LM Studio Ollama, and GPT4ALL without needing to be online, and keep your data local.

Graphics

Edit and generate images with applications like Stable Diffusion and Flux.1.

Audio

You can also auto-generate text to speech, reduce noise, repair distorted audio, and even generate music using applications such as VoiceCraft, Krisp, and Ace-Step.

Graphic-Intensive Gaming 

You don’t need to drag around a gaming laptop to enjoy high-performance gaming. Just connect Breakaway Box 850 T5 with your graphics card installed to instantly add the GPU power you need, when you need it. This solution will boost graphics performance on laptops and small form factor computers that may otherwise fall short for demanding games. You can output the enhanced graphics to four monitors — or even your laptop’s built-in display. Best of all, the GPU you install is upgradeable, so you can easily stay current with the latest generation high-performance graphics tech — something gaming laptops can’t offer.

Thunderbolt 5: Tomorrow’s Performance. Today.

Breakaway Box 850 T5 features the performance and qualities you expect from a Thunderbolt 5 eGPU plus the added connectivity and functionality you need. Transform a single cable connection from your computer into a powerful graphics and processing upgrade with a built-in Thunderbolt 5 dock. With up to 80 Gbps of bi-directional data speed — twice as fast as Thunderbolt 4 — you'll revolutionize your productivity.

Broad GPU Card Compatibility with Power to Spare for Future Graphic Cards

Built to handle the most power-hungry triple-width GPUs, Breakaway Box 850T5 is a plug-and-play upgrade that boosts performance for video production, demanding games, and AI workloads. It supports Thunderbolt-compatible GPUs — including triple-wide NVIDIA GeForce RTX 50, 40, or 30 series; or AMD Radeon RX 9000, 7000, or 6000 series GPU cards. Each GPU generation brings more compute power — with higher Watt power needs. With its robust 850W power supply, the Breakaway Box 850 T5 easily supports today’s top-tier GPUs and is ready for tomorrow’s even more demanding cards.
