DuoModo eGPU Module

Thunderbolt to eGPU Card Expansion Module

Graphics Workstation Power
If your workflow includes video 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 processors or low-power discrete GPUs that provide less than ideal performance. Happily, there’s a simple path to greater productivity—add a Sonnet external GPU (eGPU). The DuoModo eGPU Module Thunderbolt to GPU PCIe Card Expansion System boosts your eGPU-compatible computer’s graphics performance by connecting a high-performance desktop or workstation GPU card to your computer via a single cable.
Built for GPU Power
  • Provides robust and well-regulated power for current and future GPU cards
  • AMD approved for the air-cooled editions of the AMD Radeon™ RX Vega 64, Radeon Pro WX 8200, and WX 9100
  • Designed to also support overclocked NVIDIA® cards with high peak power requirements
DuoModo eGPU Module Interior
  1. Dual Temperature-controlled Noctua Fans – Provides cooling for the installed GPU card (sold separately), and the module's supporting Thunderbolt and power circuitry
  2. Auxiliary Power Connectors – Includes two 8-pin (6+2 pin) auxiliary power connectors
  3. 800W Power Supply – Supports cards requiring up to 750W, with power to spare to support future generation GPU cards with higher power requirements
Expansive GPU Card Compatibility
The DuoModo eGPU Module is designed to accommodate the most power-hungry (up to) 2.5-slot width GPU cards. It supports Thunderbolt-compatible cards(1) with popular GPU chipsets—such as AMD Radeon RX series (including VEGA GPUs); and NVIDIA GeForce® series and TITAN GPUs. Even 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.

Demanding 4K to 8K Worflows? Double Your DuoModos.
Many task times on supported applications—such as Adobe® Premiere® Pro, DaVinci Resolve™, and Maxon Cinema4D™, to name a few—can be cut significantly with one eGPU connected. But, for computers with Intel processors and multiple Thunderbolt ports, times can be slashed when two DuoModo eGPU Modules are employed. Connecting two eGPUs can multiply your computer’s graphics processing power, enabling it to handle today's demanding 4K, 5K, 6K, and 8K workflows more efficiently. Plus, a computer’s onboard discrete GPU can also significantly contribute to the aggregate performance.
