Professional GPU buying guide for CAD, rendering, video and medical imaging
How to size a workstation GPU by application: VRAM, single vs multi-GPU, display outputs, power and chassis fit, with recommended NVIDIA RTX PRO / Ada models for each use case.
Match the card to the application
| Use case | What matters | Recommended |
|---|---|---|
| 2D/3D CAD (AutoCAD, SolidWorks, Inventor, Revit) | Certified drivers, 8-16 GB VRAM, high clock | RTX A1000 / RTX 2000 Ada / RTX PRO 2000 |
| Large assemblies, BIM coordination, point clouds | 16-24 GB VRAM, more CUDA cores | RTX 4000 Ada / RTX PRO 4000 Blackwell |
| Rendering (V-Ray, Arnold, Blender, Enscape, Twinmotion) | CUDA/RT cores, VRAM for scenes, multi-GPU scaling | RTX 4500 Ada, RTX 5000 Ada, RTX PRO 5000 |
| Video (DaVinci Resolve, Premiere) 8K / HDR | NVENC/NVDEC engines, 24 GB+, 10-bit outputs | RTX 5000 Ada / RTX PRO 5000 |
| Simulation, CFD, AI development | FP32/FP16/FP8, 48-96 GB, ECC | RTX 6000 Ada / RTX PRO 6000 Blackwell |
| Medical imaging, GIS, control rooms | Certified, Mosaic multi-display, long lifecycle | RTX A4000 / RTX 4000 SFF Ada |
| Virtual workstations (VDI) | vGPU licensing, server form factor | L40S / RTX PRO 6000 Server Edition |
Checklist before you order
- VRAM first: a scene or dataset that does not fit in VRAM runs 10x slower. Add 30% headroom.
- Chassis and power: full-height dual-slot cards need 300-600 W PCIe power and 2-slot clearance; small-form-factor workstations need the SFF Ada / low-profile versions (RTX 2000 Ada SFF, RTX 4000 SFF Ada, 70 W).
- Displays: count outputs and resolution; DP 2.1 for 8K or 4K 240 Hz medical/colour monitors.
- Driver certification: check the ISV certification page for your exact application version.
- Warranty: 3-year manufacturer warranty on all professional cards we sell; registered in your company name.
Tell us the software, model size and monitors you use - we quote the right RTX PRO card or a complete workstation from HP, Dell or Lenovo.
پرسشهای متداول
How much VRAM do I need for Revit or SolidWorks?
8 GB is enough for typical models; 16 GB for large assemblies, point clouds or realistic rendering in the same session.
Can I put two professional GPUs in one workstation?
Yes, if the chassis, power supply and motherboard have the slots and 1,000 W+ PSU. Rendering and AI scale well; CAD viewports use only one GPU.
