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 Thunderbolt 3 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. 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 3 interface ensures the full 2750 MB/s of PCIe bandwidth is dedicated to the installed card. Why Sonnet?
