GeForce GTX 960M vs Quadro K620 benchmarks

For gaming, the GeForce GTX 960M graphics card is better than the Quadro K620 in our tests.

Our database shows that the GeForce GTX 960M 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 GeForce GTX 960M 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.

As stated by the manufacturer, the GeForce GTX 960M 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 GeForce GTX 960M 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.

According to the results of the hardwareDB benchmark utility, the GeForce GTX 960M is faster than the Quadro K620.
