I frequently present game builds to clients in real time. Previously, if I needed to switch from my laptop’s integrated graphics to the eGPU, I had to shut down the system, connect the dock, and restart a process that took 3–5 minutes. During that time, I lost client trust and momentum. With the RTX 4070 eGPU dock’s Hot Swap feature, I can now plug in the Oculink cable while the laptop is running. The system detects the GPU within 5 seconds, and I can launch the game or application immediately. Real-World Workflow Example I was demoing a new indie game at a trade show in Munich. The game ran poorly on my laptop’s integrated GPU, so I needed the eGPU. I was mid-presentation when the client asked to see a high-fidelity version. I unplugged the Oculink cable from the dock, connected it to my ThinkBook, and within 8 seconds, the game launched with full ray tracing enabled. The client was impressed and I didn’t miss a beat. How Hot Swap Works No Reboot Required: The system recognizes the GPU without restarting. Driver Auto-Load: NVIDIA drivers are pre-installed and load automatically. Seamless Transition: Applications continue running; only the GPU output changes.
