Quadro K1000M vs Quadro K420 comparison

According to the hardwareDB Benchmark, the Quadro K420 GPU is faster than the Quadro K1000M in gaming.

In our comparison, the Quadro K1000M 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, the Quadro K1000M 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 K420 has a slightly lower TDP at 41 W when compared to the Quadro K1000M at 45 W. TDP (Thermal Design Power) measures total heat output from the chip.

According to the results of the hardwareDB benchmark utility, the Quadro K420 is faster than the Quadro K1000M.
