Quadro K2000 vs Quadro K620 benchmarks

According to the hardwareDB Benchmark, the Quadro K620 GPU is faster than the Quadro K2000 in gaming.

Our database shows that the Quadro K620 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.

As stated by the manufacturer, they both have the same amount of memory at 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 slightly lower TDP at 45 W when compared to the Quadro K2000 at 51 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 Quadro K2000.
