Quadro K620 vs Quadro P400 specs and performance

According to the hardwareDB Benchmark, the Quadro K620 GPU is faster than the Quadro P400 in gaming.

In our comparison, the Quadro P400 has a slightly higher core clock speed. This is the frequency at which the graphics core is running at. While not necessarily an indicator of overall performance, this metric can be useful when comparing two GPUs based on the same architecture. In addition, the Quadro P400 also has a slightly higher boost clock speed. The boost clock speed is the frequency that the GPU core can reach if the temperature is low enough. The allows for higher performance in certain scenarios.

Next up, in terms of GPU memory, they both have the same amount of memory at 2 GiB. If you're planning at playing games at high resolutions with high-quality textures, you will need a lot of memory.

In addition, the Quadro P400 has a significantly lower TDP at 30 W when compared to the Quadro K620 at 45 W. Heat output doesn't match power consumption directly but, it's a good estimate.

In terms of raw gaming performance in our GPU benchmark, the Quadro K620 is better than the Quadro P400.
