GeForce GTX 750 Ti vs Quadro K620 specs and performance

For gaming, the GeForce GTX 750 Ti graphics card is better than the Quadro K620 in our tests.

Our database shows that the GeForce GTX 750 Ti 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 K620 has a slightly higher boost clock speed: the maximum frequency the chip can reach if power delivery and thermals allow.

Furthermore, the spec sheet for both these GPUs show that the GeForce GTX 750 Ti has significantly more memory with 4 GiB of memory compared to 2 GiB. Lots of memory is good when playing at high resolutions or with many monitors.

In addition, the Quadro K620 has a slightly lower TDP at 45 W when compared to the GeForce GTX 750 Ti at 60 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 GeForce GTX 750 Ti over the Quadro K620.
