Radeon RX 580 vs Quadro K420 benchmarks

In our benchmarks, the Radeon RX 580 beats the Quadro K420 in gaming performance.

The Radeon RX 580 has a significantly 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 Radeon RX 580 has significantly more memory with 8 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 significantly lower TDP at 41 W when compared to the Radeon RX 580 at 185 W. Heat output doesn't match power consumption directly but, it's a good estimate.

According to the results of the hardwareDB benchmark utility, the Radeon RX 580 is faster than the Quadro K420.
