Key Considerations for CAD Graphics Cards

1. VRAM
   More VRAM is critical for large-scale CAD projects, especially for 3D work. Cards with 16GB or more VRAM, such as the NVIDIA RTX 6000 Ada Generation, are preferred for advanced CAD tasks.
2. Compatibility
   Check the compatibility of the GPU with your primary CAD software, as some applications like Autodesk AutoCAD and SolidWorks are optimized for specific NVIDIA or AMD cards.
3. Ray Tracing & AI Acceleration
   Advanced ray-tracing and AI tools help improve render quality and speed. NVIDIA’s Ada architecture cards, for example, offer powerful AI-based tools that enhance workflow efficiency.
