Radeon RX 460 vs Quadro K620 benchmarks

According to the hardwareDB Benchmark, the Radeon RX 460 GPU is faster than the Quadro K620 in gaming.

The Radeon RX 460 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 460 also has a slightly higher boost clock speed. This is a frequency that can be reached if the GPU is cooled sufficiently and has enough power.

Next up, in terms of GPU memory, the Radeon RX 460 has significantly more memory with 4 GiB of memory compared to 2 GiB. Memory size doesn't directly affect performance, but too little memory will certainly degrade gaming performance.

In addition, the Quadro K620 has a significantly lower TDP at 45 W when compared to the Radeon RX 460 at 75 W. Heat output doesn't match power consumption directly but, it's a good estimate.

In terms of raw gaming performance in our GPU benchmark, the Radeon RX 460 is better than the Quadro K620.
