GeForce GTX 645 vs Quadro K620 benchmarks

For gaming, the Quadro K620 graphics card is better than the GeForce GTX 645 in our tests.

Furthermore, the spec sheet for both these GPUs show that the Quadro K620 has significantly more memory with 2 GiB of memory compared to 1 GiB. Memory size doesn't directly affect performance, but too little memory will certainly degrade gaming performance.

In addition, the Quadro K620 has a slightly lower TDP at 45 W when compared to the GeForce GTX 645 at 64 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 Quadro K620 over the GeForce GTX 645.
