Quadro K2000 vs Quadro K420 specs and performance

For gaming, the Quadro K2000 graphics card is better than the Quadro K420 in our tests.

The Quadro K2000 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 K2000 has significantly more memory with 2 GiB of memory compared to 1 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 K420 has a slightly lower TDP at 41 W when compared to the Quadro K2000 at 51 W. This is not a measure of performance, but rather the amount of heat generated by the chip when running at its highest speed.

In terms of raw gaming performance in our GPU benchmark, the Quadro K2000 is better than the Quadro K420.
