Quadro K420 vs GeForce 830M benchmarks

In our benchmarks, the GeForce 830M beats the Quadro K420 in gaming performance.

In our comparison, the GeForce 830M 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 GeForce 830M has a slightly lower TDP at 33 W when compared to the Quadro K420 at 41 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 GeForce 830M is better than the Quadro K420.
