Quadro K4000 vs RTX A4000 benchmarks

For gaming, the RTX A4000 graphics card is better than the Quadro K4000 in our tests.

As stated by the manufacturer, the RTX A4000 has significantly more memory with 16 GiB of memory compared to 3 GiB. Memory size doesn't directly affect performance, but too little memory will certainly degrade gaming performance.

In addition, the Quadro K4000 has a significantly lower TDP at 80 W when compared to the RTX A4000 at 140 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 RTX A4000 is better than the Quadro K4000.
