GeForce GTX 1080 vs Quadro K620 benchmarks

In our benchmarks, the GeForce GTX 1080 beats the Quadro K620 in gaming performance.

In our comparison, the GeForce GTX 1080 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. In addition, the GeForce GTX 1080 also has a significantly higher boost clock speed: the maximum frequency the chip can reach if power delivery and thermals allow.

As stated by the manufacturer, the GeForce GTX 1080 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 GeForce GTX 1080 at 180 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 GeForce GTX 1080 over the Quadro K620.
