HP NVIDIA Quadro P620 2 GB GDDR5 - Workstation Graphics Card

In this review the HP NVIDIA Quadro P620 is examined as a compact workstation graphics card aimed at professionals who need reliable display outputs and modest GPU acceleration. The bottom line: this card is best for CAD, 2D/entry 3D workflows and multi-monitor setups where stability and certified drivers matter more than raw gaming performance. Our review finds the Quadro P620 delivers consistent behavior in supported HP workstations and offers four Mini DisplayPort outputs in a low-profile PCIe 3.0 x16 form factor, making it a sensible upgrade for the specified Z-series systems.

Key Features

• 2 GB GDDR5 memory: Provides dedicated framebuffer capacity suitable for 2D drafting and light 3D models without using system RAM.
• PCIe 3.0 x16 interface: Ensures compatibility with modern workstation motherboards and delivers sufficient bandwidth for typical professional workloads.
• Four Mini DisplayPort outputs: Lets users drive multiple high-resolution displays for large desktop real estate or presentation setups.
• Workstation compatibility: Designed to fit and be supported in HP Z4 G4, Z6 G4, and Z8 G4 workstations for a plug-and-play upgrade path.
• Low-profile design: Occupies minimal internal space, helping maintain airflow and fit in compact workstation chassis.

Who It's For

The Quadro P620 is aimed at professionals who run CAD, GIS, architectural drafting, or content creation workflows that require stable, driver-certified graphics and multi-monitor support rather than raw shader throughput. It is a sensible choice for users of HP Z4 G4, Z6 G4, and Z8 G4 systems who want a tested upgrade without changing the platform.

Users who need heavy GPU compute, large models or modern games at high settings should look elsewhere for GPUs with larger memory and higher shader counts. Similarly, those who require VR or intensive GPU rendering will find the P620 underpowered for those tasks.

Pros & Cons

Pros

• Certified driver support for professional applications provides predictable stability in workstation environments.
• Four Mini DisplayPort connectors make it easy to run multiple monitors for improved productivity.
• Compact PCIe 3.0 x16 card fits nicely into HP Z-series workstations with minimal cooling impact.
• Low power draw compared with higher-end workstation cards, reducing thermal stress on the system.

Cons

• With only 2 GB of GDDR5 memory, it is limited for large datasets, very high-resolution textures, or heavy GPU compute tasks.
• Not intended for high-end 3D rendering or modern gaming where more memory and compute performance are required.

Frequently Asked Questions

Will this card fit my HP Z4 G4 workstation?
Yes, the Quadro P620 is listed as compatible with HP Z4 G4 systems and uses a standard PCIe 3.0 x16 slot.

How many monitors can I connect?
The card provides four Mini DisplayPort outputs, allowing up to four independent displays with appropriate adapters or cables.

Is 2 GB of memory enough for CAD work?
For 2D CAD and light 3D models it is usually sufficient, but larger models and complex renderings will benefit from more GPU memory.
