Radeon R5 340 vs Quadro K620 benchmarks

In our benchmarks, the Quadro K620 beats the Radeon R5 340 in gaming performance.

Our database shows that the Quadro K620 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 Quadro K620 also has a significantly higher boost clock speed: the maximum frequency the chip can reach if power delivery and thermals allow.

In addition, the Quadro K620 has a significantly lower TDP at 45 W when compared to the Radeon R5 340 at 65 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 Quadro K620 is better than the Radeon R5 340.
