Quadro K620 vs GeForce RTX 4070 specs and performance

For gaming, the GeForce RTX 4070 graphics card is better than the Quadro K620 in our tests.

In our comparison, the GeForce RTX 4070 has a significantly 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 GeForce RTX 4070 also has a significantly 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 RTX 4070 has significantly more memory with 12 GiB of memory compared to 2 GiB. Memory size doesn't directly affect performance, but too little memory will certainly degrade gaming performance.

In addition, the Quadro K620 has a significantly lower TDP at 45 W when compared to the GeForce RTX 4070 at 300 W. Heat output doesn't match power consumption directly but, it's a good estimate.

In conclusion, all specs and GPU benchmarks considered, will recommend the GeForce RTX 4070 over the Quadro K620.
