Quadro K620 vs Quadro P620 comparison

For gaming, the Quadro P620 graphics card is better than the Quadro K620 in our tests.

The Quadro P620 has a slightly higher core clock speed. The core clock speed (or base speed) is the frequency at which the GPU core runs. This metric makes sense when comparing GPUs of a similar architecture or generation. In addition, the Quadro P620 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.

Furthermore, the spec sheet for both these GPUs show that 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 P620 has a slightly lower TDP at 40 W when compared to the Quadro K620 at 45 W. TDP (Thermal Design Power) measures total heat output from the chip.

In conclusion, all specs and GPU benchmarks considered, will recommend the Quadro P620 over the Quadro K620.
