Verdict

The NVIDIA Quadro P620 is a professional, low-profile graphics card built on the Pascal architecture featuring 512 CUDA cores, 2GB of GDDR5 memory with an 80 GB/s bandwidth, and a 128-bit memory interface. Its main characteristics include a power-efficient 40W TDP that requires no external power connectors and a single-slot design equipped with four mini-DisplayPort 1.4 outputs capable of driving four 4K displays at 60Hz. The primary pros are its ISV certifications for stable performance in CAD and 3D modeling software, its compact form factor for small systems, and high-quality video encoding/decoding engines. However, its main cons are the limited 2GB VRAM which struggles with complex high-polygon scenes and its overall low raw compute power compared to modern consumer or high-end workstation alternatives.

What customers like about NVIDIA Quadro P620?

  • Excellent for Small Form Factor (SFF) builds due to its low-profile, single-slot design.
  • Very low power consumption (40W TDP), requiring no additional PCIe power connectors.
  • Supports up to four 4K displays at 60Hz via four Mini DisplayPort outputs.
  • Highly stable and reliable for professional entry-level CAD, 3D modeling, and BIM software.
  • Includes hardware video encoding (NVENC) and decoding engines, useful for media server tasks like Plex.
  • Operates quietly and stays relatively cool under standard professional workloads.

What customers dislike about NVIDIA Quadro P620?

  • Limited 2GB GDDR5 VRAM is insufficient for modern high-poly scenes or 4K texture work.
  • Poor value for gaming; significantly outperformed by consumer cards like the GTX 1650 at similar prices.
  • Lacks advanced features like dedicated ray tracing (RT) cores or Tensor cores found in newer series.
  • Official NVENC limits concurrent sessions to two streams out of the box.
  • Expensive when purchased brand new compared to its raw performance benchmarks.
  • Uses Mini DisplayPort connectors, which often require additional adapters for standard HDMI/DP monitors.
