Quadro K620 vs Quadro RTX 4000 benchmarks

For gaming, the Quadro RTX 4000 graphics card is better than the Quadro K620 in our tests.

The Quadro RTX 4000 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 RTX 4000 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.

As stated by the manufacturer, the Quadro RTX 4000 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 Quadro RTX 4000 at 160 W. This is not a measure of performance, but rather the amount of heat generated by the chip when running at its highest speed.

According to the results of the hardwareDB benchmark utility, the Quadro RTX 4000 is faster than the Quadro K620.
