Quadro P400 vs Quadro P620 comparison

According to the hardwareDB Benchmark, the Quadro P620 GPU is faster than the Quadro P400 in gaming.

In our comparison, the Quadro P620 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. In addition, the Quadro P620 also has a slightly higher boost clock speed: the maximum frequency the chip can reach if power delivery and thermals allow.

As stated by the manufacturer, they both have the same amount of memory at 2 GiB. Lots of memory is good when playing at high resolutions or with many monitors.

In addition, the Quadro P400 has a slightly lower TDP at 30 W when compared to the Quadro P620 at 40 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 P620 is faster than the Quadro P400.
