Quadro K420 vs Quadro P400 specs and performance

For gaming, the Quadro P400 graphics card is better than the Quadro K420 in our tests.

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.

Next up, in terms of GPU memory, the Quadro P400 has significantly more memory with 2 GiB of memory compared to 1 GiB. Lots of memory is good when playing at high resolutions or with many monitors.

In addition, the Quadro P400 has a slightly lower TDP at 30 W when compared to the Quadro K420 at 41 W. Heat output doesn't match power consumption directly but, it's a good estimate.

According to the results of the hardwareDB benchmark utility, the Quadro P400 is faster than the Quadro K420.
