3-GPU Workstation: AI, CAD, Blender, Video Editing and Even Gaming Tested
In this video, we build a multi-GPU workstation with three NVIDIA GPUs based on the Supermicro H13SSL-i motherboard and the AMD EPYC platform, and test how the system performs in real-world workloads.
With a total of 72 GB of GPU VRAM, this configuration is designed for local AI inference (llama.cpp), heavy video editing in DaVinci Resolve, and professional workloads such as CAD, Blender, V-Ray, and other production environments.
The topic of workstation PCs and multi-GPU systems is still poorly covered, so at ServerFlow we decided to show what really happens when three GPUs are installed in a single system: how it behaves under load, what to expect in terms of compatibility, cooling, and overall stability.
And to make things even more interesting, we also test an unusual scenario for a professional workstation - Battlefield 6, to see how a “workstation PC” handles gaming.
If you’re interested in GPU-based server platforms, AI workstations, rendering, and video editing builds, this video is definitely worth watching.
