NVIDIA Quadro P620 Low Profile, Low Power Graphics Card Review


NVIDIA Quadro P620 Power Consumption

For our power testing, we used AIDA64 to stress the GPU, then HWiNFO to monitor power use and temperatures.

After the stress test has ramped up the NVIDIA Quadro P620 we see it tops out at 34 Watts under full load and 6Watts at idle. It is very close to the AMD Radeon PRO WX 4100. The card is 40W maximum in its specifications but we did not hit that value. This is one of the key advantages of a low power GPU like the P620. Its low power operation means that it can fit in deployments higher-end GPUs simply cannot.

Cooling Performance

A key reason that we started this series was to answer the cooling question.

Temperatures for the Quadro P620 run at 70C which gets warm when under full load. At idle we saw only 29C. While power use between the NVIDIA Quadro P620 and AMD Radeon PRO WX 4100 are close to equal, the P620 runs considerably cooler.


The NVIDIA Quadro P620 is another several-year-old graphics card that just keeps on plugging away due to its small form factor, low-power use, and cool running. Like the AMD Radeon PRO WX 4100, another big feature is its 4x Mini-DisplayPorts that allow one to set up 4x 4K displays. This is useful for HFT users, digital signage, office dashboards, and others that require a number of displays to monitor various tasks. The GPUs also have NVENC support for two streams and are often used for media-transcode workloads. The NVIDIA Quadro P620 works very well for it’s is designed for, low-power, low-heat, SFF use cases.


  1. Well, that isn’t very powerful is it. Maybe that’s the point? That 4 miniDP is why we use them in Xeon E-2100 systems to power dashboards. Onboard video sucks because you’ve got different connectors. When you’re powering four displays it’s nice to have one cable.

  2. @brianmc that’s exactly the point, we recently did a build with a pair of p600’s(the immediate predecessor to this card less shaders slightly higher clock) because it needed to power 8 4k displays. Nothing fancy just plating video on it we just needed as small as possible(we used a 2u server case inside a 4u mobile rack with cables and such in the other 2u) and 8 displays. These were chosen over other options(like the 4100) due to our own bias and already having a p600

  3. the p620 can handle 3-4 HD stream for home media server like plex ?
    for now the best solution for home is the p2000 but it’s expensive for only homing use

  4. @Daniel Smith thanks now i think to buy a p2000 with unraid i dont want to buy a 1050ti or 1060 and the fix stop to work and waste my money because a need 3-4 stream for home server

  5. I too have used this Graphics card for a while and I am perfectly satisfied with the card as it is Low Profile, Low Power Graphics that is perfectly good going for me. If someone is looking for something for a small purpose and I would highly suggest them.

  6. Using this card for video decoding of multiple streams to offload the cpu in a SFF pc. Old i7 intel went from 100% consumption to 30% and the p620 runs around 50% on decode consumption.

  7. I use Quadro P620 on my SFF case and quite often I do 4K video encoding which pushes the temperature somewhere between 65-70 degree celsius and it gets little toasty. The ideal use case for these cards are mostly for multi display support unless you have a very good case with good cooling system. It’s a great card for any non-gaming machine.

  8. p620 same price as wx4100, which one should i chose?
    i using autocad and intericad – 2d and 3d rendering.
