Quadro K620 vs GeForce 840M specs and performance

For gaming, the Quadro K620 graphics card is better than the GeForce 840M in our tests.

The GeForce 840M 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 840M has a slightly lower TDP at 33 W when compared to the Quadro K620 at 45 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 K620 is faster than the GeForce 840M.
