Quadro K620 vs GeForce RTX 3080 Laptop benchmarks

For gaming, the GeForce RTX 3080 Laptop graphics card is better than the Quadro K620 in our tests.

In our comparison, the GeForce RTX 3080 Laptop 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 GeForce RTX 3080 Laptop also has a slightly higher boost clock speed. The boost clock speed is the frequency that the GPU core can reach if the temperature is low enough. The allows for higher performance in certain scenarios.

In addition, the Quadro K620 has a significantly lower TDP at 45 W when compared to the GeForce RTX 3080 Laptop at 115 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 GeForce RTX 3080 Laptop is better than the Quadro K620.
