Quadro P4000 vs Quadro P620 benchmarks

For gaming, the Quadro P4000 graphics card is better than the Quadro P620 in our tests.

Our database shows that 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. Despite this, the Quadro P4000 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 the Quadro P4000 has significantly more memory with 8 GiB of memory compared to 2 GiB. Memory size doesn't directly affect performance, but too little memory will certainly degrade gaming performance.

In addition, the Quadro P620 has a significantly lower TDP at 40 W when compared to the Quadro P4000 at 105 W. TDP (Thermal Design Power) measures total heat output from the chip.

In conclusion, all specs and GPU benchmarks considered, will recommend the Quadro P4000 over the Quadro P620.
