Quadro K620 vs Quadro P1000 comparison

For gaming, the Quadro P1000 graphics card is better than the Quadro K620 in our tests.

The Quadro P1000 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 P1000 also has a slightly higher boost clock speed. This is a frequency that can be reached if the GPU is cooled sufficiently and has enough power.

Next up, in terms of GPU memory, the Quadro P1000 has significantly more memory with 4 GiB of memory compared to 2 GiB. Lots of memory is good when playing at high resolutions or with many monitors.

In addition, the Quadro K620 has a slightly lower TDP at 45 W when compared to the Quadro P1000 at 47 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 P1000 over the Quadro K620.
