Radeon RX 560 vs Quadro K620 comparison

According to the hardwareDB Benchmark, the Radeon RX 560 GPU is faster than the Quadro K620 in gaming.

The Radeon RX 560 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. In addition, the Radeon RX 560 also has a slightly higher boost clock speed: the maximum frequency the chip can reach if power delivery and thermals allow.

Furthermore, the spec sheet for both these GPUs show that the Radeon RX 560 has significantly more memory with 4 GiB of memory compared to 2 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 K620 has a significantly lower TDP at 45 W when compared to the Radeon RX 560 at 80 W. Heat output doesn't match power consumption directly but, it's a good estimate.

In conclusion, all specs and GPU benchmarks considered, will recommend the Radeon RX 560 over the Quadro K620.
