Quadro K620 vs T400 4GB comparison

For gaming, the T400 4GB graphics card is better than the Quadro K620 in our tests.

The Quadro K620 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. Despite this, the T400 4GB has a slightly higher boost clock speed. This is a frequency that can be reached if the GPU is cooled sufficiently and has enough power.

In addition, the T400 4GB has a significantly lower TDP at 30 W when compared to the Quadro K620 at 45 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 conclusion, all specs and GPU benchmarks considered, will recommend the T400 4GB over the Quadro K620.
