Quadro K4000 vs Quadro P400 comparison

For gaming, the Quadro K4000 graphics card is better than the Quadro P400 in our tests.

As stated by the manufacturer, the Quadro K4000 has significantly more memory with 3 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 P400 has a significantly lower TDP at 30 W when compared to the Quadro K4000 at 80 W. Heat output doesn't match power consumption directly but, it's a good estimate.

In conclusion, all specs and GPU benchmarks considered, will recommend the Quadro K4000 over the Quadro P400.
