Quadro K620 vs Quadro T1000 Max-Q benchmarks

In our benchmarks, the Quadro T1000 Max-Q beats the Quadro K620 in gaming performance.

The Quadro K620 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. Despite this, the Quadro T1000 Max-Q has a slightly higher boost clock speed: the maximum frequency the chip can reach if power delivery and thermals allow.

In addition, the Quadro K620 has a slightly lower TDP at 45 W when compared to the Quadro T1000 Max-Q at 50 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 Quadro T1000 Max-Q over the Quadro K620.
