Quadro K420 vs Quadro P1000 benchmarks

For gaming, the Quadro P1000 graphics card is better than the Quadro K420 in our tests.

Our database shows that the Quadro P1000 has a significantly higher core clock speed. This is the frequency at which the graphics core is running at. While not necessarily an indicator of overall performance, this metric can be useful when comparing two GPUs based on the same architecture.

Furthermore, the spec sheet for both these GPUs show that the Quadro P1000 has significantly more memory with 4 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 K420 has a slightly lower TDP at 41 W when compared to the Quadro P1000 at 47 W. TDP (Thermal Design Power) measures total heat output from the chip.

According to the results of the hardwareDB benchmark utility, the Quadro P1000 is faster than the Quadro K420.
