Radeon RX 580 vs Quadro K620 benchmarks

According to the hardwareDB Benchmark, the Radeon RX 580 GPU is faster than the Quadro K620 in gaming.

Our database shows that the Radeon RX 580 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 Radeon RX 580 also has a slightly higher boost clock speed. The boost clock speed is the frequency that the GPU core can reach if the temperature is low enough. The allows for higher performance in certain scenarios.

Furthermore, the spec sheet for both these GPUs show that the Radeon RX 580 has significantly more memory with 8 GiB of memory compared to 2 GiB. Lots of memory is good when playing at high resolutions or with many monitors.

In addition, the Quadro K620 has a significantly lower TDP at 45 W when compared to the Radeon RX 580 at 185 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 Radeon RX 580 over the Quadro K620.
