Quadro K420 vs Quadro P4000 specs and performance

According to the hardwareDB Benchmark, the Quadro P4000 GPU is faster than the Quadro K420 in gaming.

The Quadro P4000 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 P4000 has significantly more memory with 8 GiB of memory compared to 1 GiB. Lots of memory is good when playing at high resolutions or with many monitors.

In addition, the Quadro K420 has a significantly lower TDP at 41 W when compared to the Quadro P4000 at 105 W. TDP (Thermal Design Power) measures total heat output from the chip.

In conclusion, all specs and GPU benchmarks considered, will recommend the Quadro P4000 over the Quadro K420.
