GeForce GTX 750 vs Quadro K420 comparison

For gaming, the GeForce GTX 750 graphics card is better than the Quadro K420 in our tests.

The GeForce GTX 750 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.

As stated by the manufacturer, the GeForce GTX 750 has significantly more memory with 2 GiB of memory compared to 1 GiB. Memory size doesn't directly affect performance, but too little memory will certainly degrade gaming performance.

In addition, the Quadro K420 has a slightly lower TDP at 41 W when compared to the GeForce GTX 750 at 55 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 conclusion, all specs and GPU benchmarks considered, will recommend the GeForce GTX 750 over the Quadro K420.
