Radeon RX 6500 XT vs Quadro K420 comparison

In our benchmarks, the Radeon RX 6500 XT beats the Quadro K420 in gaming performance.

In our comparison, the Radeon RX 6500 XT has a significantly 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.

Furthermore, the spec sheet for both these GPUs show that the Radeon RX 6500 XT has significantly more memory with 4 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 significantly lower TDP at 41 W when compared to the Radeon RX 6500 XT at 107 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 Radeon RX 6500 XT is better than the Quadro K420.
